How To Prolong Laptop Battery Life Time Of Independence

Sun, 20 Jun 2010 08:02:34 +0000

How to prolong laptop battery life time of independence

Notebook greatest advantage is that we can place in the absence of AC power mobile workforce and notebook PC battery can support the machine known as continuous 2 to 4 hours, but despite the new battery is often also insist on 1.5 to 2 hours. The following to introduce a few can make a small laptop computer energy saving methods, so Dell Inspiron 6400 Battery our laptop batteries can be used independently longer.

Optimization of shutdown mode

If, within a few hours after shutdown does not require re-open the notebook, you can use the “off” mode Turn off the computer, because even if the notebook computer “Standby” will also be micro-power consumption; if the temporary closure of a moment but also the use, you can select “Standby “This saves re-boot the waiting time can also be reduced because of the hard disk boot a large number of visits to bring action to save power. In short, we should wake up interval in notebook computers, and to find a balance between power consumption.

Reduced peripheral

The use of battery-powered notebook computer work, to minimize the external USB or PCMCIA devices, in particular, external devices, the “big power”, such as: external hard drive or CD-ROM and so on.

Disable rarely use the equipment

Infrequently used built-in device can be disabled, so that the system will suspend the supply of these devices, for example, you can stop infrared, Bluetooth, LAN and other devices. Can be in the “Device Manager” and double-click the device you want to disable, and then “Properties” – “General” page will be “Equipment Usage” project the words “Do not use this Dell Inspiron 8600 Battery (disable).”

Through the discharge time of battery-powered

If the battery usage time is too long, power may be too short, we can be alone for the computer on battery power until the battery remaining 10%, then non-stop charging, so that alone can increase the battery life. Under normal circumstances would be to set up a laptop battery alarm and protection of the minimum value, this value is usually 5 to 10%, if the battery is lower than the value of this protection system will automatically shut down, so that the effective protection of the laptop computers and battery life.

Disable Screen Saver

If you use a more complex screen saver, in fact, than a normal laptop use more power. In the absence of necessary, to minimize the opening screen saver to extend battery life.

Appropriate down-conversion

When you need AC power supply situation in the absence of working long hours, but does not require a very high-performance notebook computers, you can use some down-conversion software, CPU to CPU temporary down-conversion in order to get more battery life time of independence. As we all know, CPU is the computer’s power-hungry, especially in its high-speed operation when the power is high, through the down-conversion, can reduce its electricity Acer Aspire 1410 Battery.

Power Management Mode

Whether in the long-distance journey, or during a power outage, or unexpected events, it is important to a laptop the way to pass the time, so laptop power to maintain filling of insurers. And often need to use the notebook computer’s friends to go to work, the most disturbing is the encounter laptop power ineffective, unable to breath the job done. Wanted laptop power, what recipe is nothing more than power of two parts: software and hardware. Here’s two-pronged, let me come for you 11.

With win2000 as an example (other systems and win2000 are similar) in the control panel there is a “Power Options” (as shown in Figure 1), open the “Power Options” a “Power Options” window (shown in Figure 2 shown), you can see the “Power Schemes” tab within the “Power Configuration” option, the “home / office-type”, “Portable / Laptop”, “demo”, “always open”, “Minimum Power Management “,” Max Battery “and other projects. When you select a different power configuration item, the bottom will display a different power configuration settings. To “close the Monitor / General Power / 10 minutes”, it represents is the “Connect the power supply situation in general, do not touch the keyboard or mouse will be closed 10 minutes after the monitor power,” so that we can achieve the purpose of saving . For example, when you use a computer when he suddenly received a telephone chat client for 10 minutes, the computer will automatically power off the display until you touch the computer again, it will re-open.

The so-called “system standby that is, when the computer after a period of stagnation, the system will be saved in the current working-memory, and peripherals (monitors, hard drives, etc.) the power off, but the power is still open (power indicator is still lit ), as long as you touch the mouse or keyboard, the computer will revert to your original working condition. As for the “System hibernates” malpractices in-memory data is stored to the hard disk, and the computer power off (power indicator goes out), At this point as long as the re-opened by pressing a key, the computer will revert to your original state of the work. WindowsXP the default is not open “system sleep” mode, you must be in the “Power Options” window to open the “dormant” label page, and “Enable Hibernation” check box is ticked, this way, we can in the “Power Schemes” tab to see “system sleep” setting. you want to quickly look at the current battery remaining amount, in addition to the Control Panel “Power Options” window, look at the battery meter “, you just in the” Power Options “window of the” Advanced “tab click on the” automatically displayed on the taskbar icon “, you can through the task bar on the battery (or power line) small icon, easy to look at the remaining battery power of the.

What is the run time of HP Compaq laptop battery

Sat, 19 Jun 2010 12:07:33 +0000

HP Compaq Laptop Battery have two main ratings on them: Volts and Amperes. Because size and weight of Laptop Battery is limited when compared to larger batteries such as car batteries, most companies show their ratings with Volts and Mill amperes. One thousand Mill amperes equals 1 Ampere. When buying a battery, select batteries with the most Mill amperes (or Ah). Batteries are also rated by Watt-Hours, perhaps the simplest rating of all. This is found by multiplying the Volts and the Amperes together. For example: 14.4 Volts, 4000mAh (Note: 4000mAh is equal to 4.0 Amperes). 14.4 x 4.0 = 57.60 Watt-Hours Watt-Hours signifies the energy needed to power one watt for one hour. This HP Compaq Laptop Battery can power 57.60 watts for one hour. If your laptop runs at 20.50 watts, as an example, this Laptop Battery could power your laptop for 2.8 hours.

133 Watt External Laptop Battery Charger Runtime Up to 10Hrs

Upgrade my HP Compaq Laptop Battery from Ni-MH to Li-ion

Ni-Cd, Ni-MH and Li-ion HP Compaq Laptop Battery are all fundamentally different from one another and cannot be substituted unless the laptop has been pre-configured from the manufacturer to accept more than one type of battery chemistry. Please refer to your manual to find out which rechargeable battery types the laptop device supports or use our HP Compaq Laptop Battery Finder above to find all the compatible Laptop Battery for your device. It will automatically list all of the battery chemistries supported by your specific device. If your device does allow you to upgrade the battery from Ni-MH to Li-ion, you will typically get longer run times.

For example, if your laptop uses a NI-MH battery that is 9.6 Volts, 4000mAh and the new Li-ion laptop battery is 14.4 Volt, 3600mAh, then you will obtain longer run time with the Li-ion battery.

Example. Li-ion: 14.4 Volts x 3.6 Amperes = 51.84 Watt Hours Ni-MH: 9.6 Volts x 4 Amperes = 38.4 Watt Hours The Li-ion is stronger and has longer run time.

Three Controversial Xiangjie Laptop Battery

Fri, 18 Jun 2010 18:13:39 +0000

Three controversial Xiangjie laptop battery

As the price of notebook batteries are expensive “consumables”, it triggered a lot of use of arguments.

With the increasing popularity of notebook computers, notebook computers on all aspects of the problems cropped up in various media on the largest number of arguments the proper use of laptop batteries, notebook batteries some articles say that the use of personal experience, while others claim expert guidance, all kinds of stories are, the argument

The author is also a regular laptop user, although not an expert, but with many years experience in the use of notebooks, the author through a friend recruited dozens of university students using a laptop, so that they talk about their experiences on the use of laptop batteries, coupled with its a little more experience, summed up what made available to everyone as a reference, hope to give everyone a little help.

Argument 1:

Activation of a new battery

Point 1: before buying a new battery inside, there will be more than 3% of electricity, more than the battery inside the power exhausted, until the shutdown, and then re-use an external power supply charge. Charging time must be more than 12 hours, repeated three times to do in order to activate the battery.

Point 2: No, the battery for 10 hours of rechargeable battery to activate the activity of the normal charge-discharge method for activation.

Survey Results: The author investigated and 24 college students laptop users, 18 is the second point of view, and that such manner and does not charge the battery for future use can hurt, of course, to exclude damage to the natural elements. The author himself is also the case when the normal use of a new battery for up to two and a half hours, now two years past, the status of the battery is still good, still can reach more than two hours, so I have been

The proposed method: I agree with the second view, based on available information indicates that the activation of cell work should be completed at the factory, and laptop battery factory with a capacity of some natural wear and tear in order to avoid damaging the battery. Activation of the battery should be in no circumstances to protect the circuit can be with its own lithium battery circuit protection circuit, the purpose of this piece of the circuit is to avoid excessive battery charge and discharge, generally filled with the battery after charging when the indicator light off , the battery can not be recharged into the electricity, and then you then plug the power plug to recharge the battery in the face of what use?

Available from the battery can be seen on the status of the battery have any charge, another teaches you a simple way to be able to determine whether there during the battery charging, battery charging, when the phenomenon will have a fever, when the battery is full after one hour (power plug does not pull), you go try the battery to see if the battery is still warm not hot?

The result is definitely cold, because the battery is not charging and discharging state certainly does not heat. Notebook makers at the factory will propose that a new battery for more than 10 hours. This sentence may be generated for some users the wrong point of view first, the author of this opinion, should be taken into account that some notebook manufacturers a new user in the new battery charge when not fully grasp the skills, simply so that they can charge directly 10 hours, so this should be the business of expediency.

Argument 2:

Whether an external power supply unplug the battery?

View 1: Use an external power supply when the battery removed.

Point 2: Use an external power supply is not required to remove the battery.

Survey Results: Most students in the use of an external power source, will the battery removed, only a few use an external power supply when the battery is placed above, that the few brands are used by students in several international brand.

The proposed method: In fact, if the battery is removed, the focused on the use of an external power supply when the battery is charging to the issue. We should know that the number of charging and discharging the battery life is directly related to the general lithium battery set the number of charging and discharging are fixed number of charge cycles only 400-600 times, specially modified products, but 800 times, once for each rechargeable batteries a step forward to retirement. The first argument is simply because they are afraid to use power, the battery will be conducted on the above charge, not only increase the number of charge cycles, but will also cause overcharge.

The second view is that the battery is full power on the computer in the use of an external power supply will not recharge. In fact, both views have their right side, but also the wrong place. Because it is only the views expressed by individuals is not very comprehensive, after I investigated, many notebook manufacturers are taking into account the vulnerability of the battery, and the product added to the battery protection technology, and thus the corresponding different brand laptop batteries Charging protection technology is different, like some large companies do very well in this regard, such as: IBM, Hewlett-Packard, Toshiba, Compaq, etc.. One of the most thoughtful consideration is that IBM, IBM’s notebook computers can detect the battery discharge situation, ThinkPad notebook battery only less than 95% of the time will automatically recharge.

This can play a good protective effect on the battery, and now many other manufacturers have followed suit. So, like the battery, you do not have the time to use pull down, because only when the capacity less than 95% of the time it would charge. But even so, if you are prolonged use of computers, or will the battery be removed to compare the good, because the long-running laptop heat generated when the battery will cause some damage. However, some other “little brand” laptop batteries, may not enjoy such treatment, because it has not done inside the battery protection technology.

I like to use a certain brand of notebook computers, if the fully charged battery on the above, when using an external power supply was confirmed when the first charge about electricity, because the battery storage, will have wear and tear, can not reach 100%, while not 100% as long as , power supply connected to the charge. Each access to external power Dell 1691P Battery is equivalent to charging the battery once, although only a small charge will be the time. Therefore propose that we use when the machine according to their own circumstances, look at the laptop manual, choose whether to use an external power supply when the battery removed.

Argument 3:

How to correctly charge?

Point 1: The battery power should always be all exhausted, so that consumption of notebook computers to automatically shut down and then recharge, each must be filled.

Point 2: when the battery is very deliberately not to pay attention to, and use when I wanted to charge to charge.

Survey Results: Most students said that, unnecessary to the first view, as used in automatic shutdown and then charge, but also like the second point of view, it is free of charge. Are generally used when the battery needs charging when the computer prompted further charge, of course, prompts the time can be set, the default is to 3%.

The proposed method: In this paper the proposed method with the majority of the students is the same. In fact, regardless of laptop use nickel-metal hydride or lithium batteries, these batteries are have a memory effect, and nickel-metal hydride batteries with HP pavilion dv6000 battery effect is very obvious, but equally there will be lithium memory effect, but its memory effect smaller than the nickel-metal hydride Bale . There is no memory effect on lithium to say, only exaggerated and irresponsible business conduct in advertising, is totally misleading.

Well, since the battery has a memory effect, it should be noted when charging point, as far as possible and then run out of charge, but do not have to deliberately say must use the computer to automatically shut down, so that although there is no harm in using them (because the laptop battery has a charge-discharge secure, laptop automatically shut down has not yet reached the standard battery discharge protection), but you do not feel so tired? In fact, less than 3% of the charge in this way is very good, memories will certainly be the effect, compared to natural wear and tear to said that it was nothing.

As for the second charge on the charge to the view, the author is completely disagree, and have already said, whether laptop battery nickel-metal hydride or lithium, which has a memory effect, if in this way then the battery life will be

Types Of Laptop Battery

Thu, 17 Jun 2010 02:25:22 +0000

Types of laptop battery

Battery refers to chemical energy, solar energy, nuclear and other forms of energy into electrical energy. It is divided into a battery (commonly known as Dell Inspiron 8600 Battery cells) and the secondary battery (rechargeable battery can be repeated), as technology advances and the development of the battery through the photovoltaic cells from the initial to the nickel-cadmium batteries, nickel hydrogen batteries, lithium batteries ( including lithium batteries and lithium polymer batteries) and is developing fuel cells. Each technological innovation not only makes the battery capacity, weight, ease of use have a major breakthrough, but also becoming more environmentally friendly.

Notebook battery types and characteristics:

Nickel-cadmium batteries (Ni-Cd): It is used in notebook batteries in the veteran, but because it has a serious memory effect and anode materials used in Nickel (Ni) of toxic and cause pollution to the environment, so it is hang on a laptop soon be replaced by a more excellent Ni-MH battery.

Ni-MH Battery (Ni-MH): Nickel-cadmium batteries with the same structural principle, but will be replaced by the cathode performance better, more environmentally friendly non-toxic nickel – metal hydride materials. Although only a small change, but it brought great performance to improve. It also has a hard act to make the advantages of nickel-cadmium battery memory effect is not obvious, so that so that we no longer need to worry that nasty memory effect and thus more convenient to use. Although the performance of NiMH batteries is very good, but as technology advances it is lighter, higher energy density lithium batteries are replaced, become the laptop battery in the history of deadwood.

Lithium battery: Many people said that lithium batteries that we are now commonly used in lithium polymer batteries, lithium batteries, including lithium ion batteries in fact (Li-MO2) and lithium-polymer battery (Li-ion) of two. Because Li-MO2 battery market in 1989, when a premature explosion fire, so it quickly disappeared from view, replaced by safer lithium-polymer battery. It is light weight, in the case with the capacity of its Ni-MH battery weighs only about 1 / 2, so it quickly for mobile portable device’s new darling, Pitaiduoshuo notebook Diannao Suo Shi Yong, yes Xianzai Biji Ben battery Zhong’s backbone.

Fuel cell (Fuel Cell): Fuel cells are the future of laptop IBM ThinkPad T60 battery star, it has many types, including proton exchange membrane fuel cell (PEM), alkaline fuel cell (AFC) and solid oxide fuel cell (SOFC) and other However, as the fuel cell start-up time and operating temperature and other factors actually used for notebook computers only proton exchange membrane fuel cell fuel cell (PEM). PEM fuel cell using the fuel is methanol, the positive and the negative electrode, it is the principle of generation of hydrogen through the reforming of methanol after the negative input, positive input of oxygen through the catalyst, hydrogen atoms into protons and electrons, by the different paths into the cathode, e-cycle to produce electricity through an internal, proton through the electrolyte to the anode, when combined with oxygen to produce water and electrical and thermal. The experts agreed that restricting the commercial application of fuel cells the most important factor is the fuel cell to use the metal platinum (Pt) or platinum as the catalyst to the production cost has been high, the current production costs of fuel cells in the 500 to 1,000 USD / kW. Studies have shown that only when the production costs of fuel cells down to 50 dollars / kW level around can really accepted by consumers. The main reason for the high cost of fuel cells is not mass production, Once in production, the fuel cell’s information will certainly be greatly reduced.

The biggest advantage is the laptop mobility, provide the basis for all this is the battery. In the energy-saving technology and battery technology for the time being when there is no breakthrough, the full optimization of the battery and have some relevant tips will be helpful. However, long laptop battery life, it is often sufficient dissatisfaction and even damage the battery, and therefore must pay special attention to a number of techniques used.

First, choose the best time to repair

Laptop battery aging phenomenon is inevitable, almost all of the repair methods are trial “deep charge deep-release” principle, in order to ease the battery memory effect. Undeniably, however, the depth of the charge and discharge operation will not be good for the laptop battery itself is a method may not be at it. If battery life is only to reduce the tens of minutes, IBM ThinkPad R50 battery care should be taken to that method of operation. In addition, battery manufacturers have been optimized, there is no self-depth again to upgrade the battery charge and discharge capacity of the argument. But how when you need it is difficult to grasp the depth of discharge, after all, every time the electricity consumed is not the same, therefore we recommend using BatteryMon this professional software.

BatteryMon is a specifically for the small laptop battery monitoring software, especially for those without built-in power management chips and software for the machine, it certainly helped a lot of great help. BatteryMon most salient feature is able to discharge curve, and the installation will run automatically. A good performance will have a very regular battery discharge curve, as shown, is basically a grid of time each fall about the same. If found to have a very unusual beat, then it is necessary to carry out the battery “full of deep dark place” repair.

Second, “full of deep dark place,” the basic method

Battery calibration is an effective way to deal with aging batteries, in general, each brand will have a dedicated laptop battery calibration software. For example, IBM’s ThinkPad series have a dedicated discharge software is recommended for all users to use IBM notebook. But the process need to be repeated three times to get the best results. Download the software and the implementation of discharge, the system will be prompted to create installation disks. Use the installation disk boot PCDOS, unplug the AC power supply prompted the discharge control software will automatically discharge. When all the notebook will automatically shut down after, and then we can connect the AC power source for charging, time control in 9 to 12 hours, repeatedly 2 ~ 3 times.

Laptop battery for activation, we find the right key to discharge the software. Unfortunately, if your laptop is not specialized discharge software, it can be shut down in the BIOS and Windows power management features, then do not run any programs in case the battery Dell INSPIRON 9400 Battery out, then recharge in the boot state to about 80% was repeated several times such as after manual “full of deep dark place.” In fact, this approach aims to enable the continuous low current discharge batteries, which discharge state in our daily use is unlikely to be achieved, the effect of discharge and those dedicated basically the same software.

Software products on the laptop will affect the battery life in battery mode, the time issue has been somewhat controversial, but the problem now appeared to have no suspense, not only because of Microsoft’s operating system through the previous “ACPI driver BUG power” to the dispute already have results, but with Microsoft’s Windows Vista operating system, a large area of popular software products can shorten battery life of notebook computers have irrefutable conclusions.

Recently, a foreign media reported that as the Windows Vista operating system during the course want to turn the Aero Glass 3D user interface, indirect Or directly increase the notebook’s power capacity, said plainly, that the use of procedures as Aero Glass needs continuous system work to reflect, and then to CPU, graphics and display units such as continued heavy load of work, thus allow laptops require more power to meet the needs, and if the battery-powered model in the most direct result is a significant the shortened battery life, Vista “beautiful price” so.

In fact, from deployment to Vista on the notebook the day, its high power consumption has always been a concern, but now that concern consumers have been upgraded from general to many notebook computer manufacturers, such as HP and Lenovo and other well-known notebook manufacturers on this rather unhappy, we can see in the future, we focus on hardware energy efficiency in notebooks, while they should be from Microsoft software on the laptop to stop “tapping” the.

Microsoft’s operating system is recognized as the first big power Acer Aspire 1680 Battery the notebook platform, the “proposal” to optimize the improvements Microsoft have the same time, a more direct question is in the future, the number of software products will be a notebook computer Battery “life killer” or energy-saving notebook on the road, “stumbling block”!

Understanding, Clever Use Of Laptop Battery

Wed, 16 Jun 2010 00:59:55 +0000

Understanding, clever use of laptop battery

Use rechargeable batteries for notebook computers advantages relative one desktop, it can greatly facilitate the environment in a variety of laptop use. Introduced the first battery is nickel-cadmium battery (NiCd), but this battery has a “memory effect”, each charge must be discharged before, very easy to use, soon to be nickel-metal DELL 451-10326 battery battery (NiMH) are replaced, NiMH is not only not “memory effect”, and the weight per unit can provide 10% more power. The most commonly used battery is lithium-ion battery (Li-Ion), it is no “memory effect” compared with NiMH, get more weight per unit of electricity prices twice as high than NiMH. Under the same weight, the three battery is 1:1.2:1.9 ratio.

Currently the batteries used in notebook computers are three main points: 1. Nickel-chromium batteries, 2. Ni-MH battery, 3. Lithium battery; they are generally expressed as: Nickel cadmium NI-CD, Ni-MH NI-MH, lithium LI.

Purchase or replace the battery when the laptop for many users, the “batteries” may be unfamiliar. At the outset, batteries and battery are two concepts. A battery is slightly larger number than the thumb, cylindrical, height of about 7,8 cm, voltage 3.6v small units. They are the batteries, like a small battery, in series combination, we see that the battery was. Then talk about how to judge the battery is the core of a few:

One way: unplug the battery number of contacts to see him, there is some core of a few. But it is the “minister” means. We take a look at “Cao Chong” is how “said elephant”: a look at how much of your battery v nominal, such as 14.4v, then divided by 3.6 by 4, then proved to be four batteries together in series. Then look at the capacity of the battery block, for example 3800mAh, then prove that the two groups mentioned above, the series battery, because the small battery capacity of 1500-2000mAh, or even more, to two groups to reach 3800mAh. According to the two judgments, then the battery is 4 × 2 = 8 cores.

The composition of laptop battery

Laptop batteries by the case, circuit boards and batteries, belonging to lithium-ion battery. Ordinary people talking about batteries means the number of DELL INSPIRON 5000 SERIES battery within the battery, mAh refers to the capacity of notebook batteries.

Mainly by the protection circuit board (or secondary protection), and the capacity indicator circuit composed of two parts, on the laptop battery charge and discharge and safety management.

Laptop battery standby time determined mainly by the mAh value. In general, the more the batteries, mAh greater the longer standby time. Notebook battery life mainly to measure the charge and discharge times, the quality of the products qualified for the 500-600 times normal. Therefore, the effective use of laptop battery within a period of 2 years, the battery will expire aging, the drastic drop in standby time of impact notebook mobility.

Notebook Battery Tips

In fact, how to make good use of laptop batteries battery, how to extend their use of time and the use of life issues, no doubt troubled by the majority of notebook users a heart problem, laptop computer batteries and use a variety of techniques, which requires us to usually use more learning and application.

(A) fast into hibernation

Temporarily using a laptop, in order to save battery power, we can set the power management program, allowing the system after a period of time to sleep, but shorter or longer will have to wait a few minutes, there is no way to make notebook computer system immediately enter the sleep state?

The notebook system quickly into hibernation a simple method is to directly turn off the display. Press the display is just little things, you can make notebook computers into hibernation immediately and effectively conserve battery energy. When you need to re-use it, simply open the display, the system will automatically return to operation as before.

(B) of the screen power-saving mode

TFT screen notebook computer power consumption is the largest Dell Latitude D610 Battery, in order to reduce its use of the battery when the power consumption, notebook manufacturers have different tactics, but in general are based on the lower screen brightness, or even turn off the screen method.

In some notebook power management settings can customize the brightness of the screen, most laptops can be adjusted by a specific shortcut screen brightness, generally 6 to 8 level brightness adjustment.

(C) energy-saving settings

Desktop using alternating current, most energy-saving features on computers may not be very great importance, but need to use battery-powered laptop computer for the use of energy-saving features should be taken seriously. How to design computer hardware more energy-saving, this is not a user problem to be solved. Users can do is set the computer to effectively use the energy saving option.

Energy-saving setting, there are two require the user to adjust: First, the computer BIOS Setup program settings on the energy saving mode; most important thing is there are many energy saving in the operating system setup and operation. Computer system in the actual implementation, Windows system should take precedence over energy-saving settings in the CMOS settings.

1. BIOS settings in the Energy

In the CMOS settings, has a large “Power Savings”, which can choose to “Maximum Battery Life” and “Maximum Performance” and other options. “Maximum Battery Life” is the default energy-saving mode setting. Laptop power saving mode in several states, such as the Idle Mode Idle mode, Standby Mode standby (wait) mode, Suspend Mode suspension (sleep) mode. Dell Inspiron 8000 battery computer these settings have been able to regulate power consumption, mainly in the computer into energy-saving state, the timely closure of the system without the use of equipment. If the wait state, close the display and hard drive; into hibernation, apart from off the display and hard drive, but also the contents of memory can be saved to the hard disk, the basic maintenance of the entire computer system shut down state, once activated, or restart the computer, desktop will accurately return to sleep as before. The energy-saving settings in the CMOS, mainly set by the Idle Mode to enter Standby Mode of the Standby Timeout time set by the Standby Mode to enter Suspend Mode of Suspend Timeout time. Phoenix BIOS notebooks are most common. Different energy-saving BIOS settings may be different, should carefully read the screen prompts.

2. Windows in the energy-saving settings

For general users, in the Windows system to operate a better understanding of energy management can be simpler. Windows Help file, in the “management hardware and software” entries, there are two notebook computers with energy-related elements: “Energy Management” and “use of portable machine” in the “management of portable computer power.” Windows energy saving settings before making should read the content.

In the Windows “Control Panel”, click “Power Management”, you can open the “Power Management Properties” dialog box. In the “Power Management Properties” dialog box, should be “power scheme” is set to “Portable / Laptop” and rationalize “the system to wait”, “close the Monitors”, “Turn off hard disks” and other options . Different computer can control the options have some differences, the new factory and the latest computer software will be more workable option, a detailed set of functions should be based on the computer itself and the Windows help file to be.

In addition, if your laptop built-in infrared port, not when Asus EEE PC battery ban it, can extend laptop battery life.

(4) alarm settings

Set the battery alarm in time to prompt the user to save the information. By clicking open the “Control Panel”, double-click “Power” menu, click on “Alert” menu bar “-battery alarm” bar Windows 98 default is 10%, “a serious shortage of battery alarm” bar Windows 98 default is 3% can make the appropriate modifications as needed. Click both the [alarm response] button, the “Sound Alarm” and “displays the message” is selected, the “power level” may from time to choose. Alarm limits so that when the battery is used, it will pop up a warning window, and the alarm buzzer sound to prompt the user to save information in a timely manner. Finally click [OK] button to exit the power management settings.

(E) open the energy-saving features

In the “extended laptop battery technology” section, we have introduced energy-saving feature is the use of a CPU technology, which allows play to give the performance of laptop battery time between its optimum balance.

Most new models of notebook computers are on the CPU in the BIOS in the energy-saving technologies to support, by default is turned on, if not open as long as the option to enter the BIOS will support the open on OK.

(F) the use of third-party software to monitor battery status

In addition to Windows built-in power management HP Pavilion ZV5000 Battery, there are many tools available to monitor program use state of the battery. For example, PowerCenter is a power monitoring tool available for free download (http://me MBers.xoom.com / TimothyBug / powercenter / index.htm). Only 800KB, is a notebook computer services for the software. PowerCenter also shows the percentage of battery capacity, but also to display the actual time and hours of time available.

PowerCenter total of three kinds of display.

(1) FullDisplay: In the open window shows detailed information, including the use of battery or AC power, the percentage of battery remaining and available time.

(2) CompactDisplay: in use are always in the top of the window display.

(3) MinimizeDisplay: to PowerCenter down to Windows task bar, the information displayed is relatively simple.

PowerCenter is also attached to a control center, made up of 6 warning. When the battery – down to a certain level, a warning to the user in a timely manner to preserve the documents being processed. In order not to waste electricity and CPU resources, PowerCenter automatically detect the battery status changes.

(G) intentionally used up battery

Run out of battery on a regular basis to ensure a full charge. If you need to completely run out of battery power in the specific practice: the Power Management dialog box, select the Battery Drain power of this particular model to all three Running on Batteries options are set to Never, this notebook is the computer on will continue to run. Select the mode, and then enter the Alarms tab, remove the Low Battery and Critical Battery Warning check box in the check mark (so that when the battery power is low, the machine will not enter ASUS A3 SERIES Battery suspended state). Next, let the computer run the CPU-time tasks, such as the computer automatically runs some of the computational complexity of the 3D demo program, it will soon run out of battery power remaining, of course, these disposal not forget to unplug the AC plug.

Researchers step closer to stopping laptop battery fires

Cambridge researchers have uncovered a way to “see” inside lithium batteries to help prevent them from catching fire.

Lithium-ion batteries are frequently used in gadgets including laptops, but are known to sometimes overheat and catch fire. Packard Bell last year recalled laptops over battery problems, as have Acer, Lenovo and others.

This is because tiny fibres – called dendrites – form in the batteries when they’re charged to quickly or frequently, causing short circuits, overheating and even fires.

Professor Clare Grey of the Cambridge Department of Chemistry said: “These dead lithium fibres have been a significant impediment to the commercialisation of new generations of higher capacity batteries that use lithium metal as the anode instead of the carbons used today.”

Until now, it’s been difficult to study the phenomenon. But Grey and her fellow researchers at the University of Cambridge have started using Nuclear Magnetic Resonance to look inside the batteries and watch the “chemistry in action.”

“Now that we can monitor dendrite formation inside intact batteries, we can identify when they are formed and under what conditions,” Grey said in a statement. “Our new method should allow researchers to identify which conditions lead to dendrite formation and to rapidly screen potential fixes to prevent the problem.”

That could lead to such batteries being used in battery powered cars, she noted. “Fire safety is a major problem that must be solved before we can get to the next generation of lithium-ion batteries and before we can safely use these batteries in a wider range of transportation applications.”

Universal Laptop Battery Purchasing Guide

Mon, 14 Jun 2010 13:31:09 +0000

Most people own more than one laptop unit and of different brands. Owning a universal laptop battery seems to be the most convenient way to have when you travel as it allows you to use it with any laptop computer unit when your power supply is running out.

It is true that taking care of your laptop battery is a priority as your mobile computer will be useless with a defective battery on it. There is a need to ensure that it works properly in order not to hamper your convenient usage of your notebook. Proper care of your laptop requires its storage in moderate temperature which is neither too cold not too hot. Your laptop battery will be short of power once it is cold and it will not discharge fast when it is hot. You need to frequently charge your battery to ensure it to be fully functioning well.

Going for a universal battery for laptops allows it to work on different models, brand, and units. There are varieties of choices available in most computer shops and online stores. But do know what type of universal battery to buy for your laptop?

One issue with laptop batteries is the danger of explosion. It may rarely happen but it does happen and anyone could be at risk when using poor quality battery for their laptops. Take note that lithium ion laptop batteries, which are commonly used in the market could explode owing to its cobalt oxide content.

Consideration may be directed also by choosing a laptop that is smaller in size such as ultra portable or light weight laptops. They have smaller LCD and it uses less power. It has a hard drive that runs only about 4200 rpm which uses less power than those than run at 5400 rpm. This makes your laptop battery drain less quickly.

Universal batteries for laptop use are available in different types according to the size of your laptop. A friend bought a nickel metal laptop battery which is suitable for her small size notebook. I want to buy one myself however I was advised it is not suitable for my laptop which is 16 inches. The most suitable one is the ED369 battery which is best for laptops that are 13 inches or more in size and when one uses a lot of external devices that requires more battery power. This battery provides 2 to 3 hours of power supply in normal conditions. Simply plug it into the AC adapter of the laptop and it is ready to use.

When buying a battery for your laptop always consider the size of your computer and the average consumption of power. You can choose from variable output voltage. Voltage of 16 and 19 v DC are enough to supply most laptops.
