Notebook Battery Tips

this paragraph] The composition of laptop battery
Laptop batteries by the case,.Acer aspire 5520 Battery circuit boards and batteries, belonging to lithium-ion battery. Ordinary people talking about batteries means the number of batteries 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

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
For the time being not to use laptop computers, to save battery power, we can by setting the power management program, the system Zai entered hibernation period of time, or long or short Douyao Danzhe such Shang a few minutes, there any way the notebook computer system immediately enter the sleep state? the notebook into hibernation system a quick and easy way 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 is the largest notebook computer power components, 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, it is not 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-saving settings in the CMOS, has a large "Power Savings", which can choose to "Maximum Battery Life" and "Maximum Performance" and other options. "Maximum Battery Life" energy-saving mode is the default 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. These settings on the laptop, was 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" entry under the two energy-related with the contents of laptops:Acer aspire 5920 Battery "Energy Management" and "use 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.Acer as07b31 Battery 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" option, etc. . Different computer can control the options have some differences, the new factory and the latest computer software would be more workable option, detailed settings should be based on the functions of the computer itself and the Windows Help file for. In addition, if your laptop built-in infrared port, not when the 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% be appropriate changes 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, a CPU energy saving feature is the use of technology, it can make the performance of laptop battery life to play with the best balance between the time to achieve. Most new models of notebook computers are on the CPU in the BIOS in the energy-saving technologies to support, is enabled by default, 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 features, 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, the taskbar to show the information 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, save the file 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 the suspended state). Next, let the computer run 时间 CPU intensive tasks, such as the computer automatically run a number of Jisuanfuza's 3D demo program, so Henkuai will run out of battery power remaining, of course, for Zhexiechuzhi not forget to unplug the AC plug.
(8) the first activation of laptop battery
Most notebook computer manufacturers in the product when leaving the plant are said to buy a new notebook computer should be in full discharge of the case, repeated three times on the battery fully charge / discharge, charge, preferably more than 14 hours. Is so short, so that the notebook computer users had a wrong view. In fact, the notebook computer products at the factory before the battery will activate, in order to avoid wear and tear affect battery performance, with a small amount of electrical energy will be. Since the completion of a laptop battery is fully charged, it will automatically stop working, there is no need to maintain the charge time to 12 hours. All in all, buy a new laptop just follow the normal charge / discharge can be activated manner.
[Edit this paragraph] method of repair laptop battery
(A) causes damage to the battery
Notebook computer battery a long time, I am often dissatisfied with electricity charge, and even the battery is damaged, the specific performance is larger resistance, the voltage across the charging up faster. This easy to charge control circuit judge to have full capacity also falls. As the larger battery internal resistance, discharge voltage drop when a large, fast, so the system is easy to mistakenly believe that voltage is not enough power is low. Comparison of the discovery of short battery life, should take corresponding measures.
(B) of the battery refresh program to restore the battery's discharge time
Big brand laptop has a battery refresh program, we can use it to repair the battery. For example: a IBMThinkpad390/262650 based laptop, the distribution for the nickel-metal hydride battery (Ni-Mh) batteries, as usual discharge properly, leading to the battery discharge time is short, only less than 5 minutes, if bring laptop to work, then it is very inconvenient, what can it restore the battery's discharge time? for the above, we can use IBM in its battery refresh program to refresh the battery put it back in discharge time, specific methods are as follows . (1) the use of AC power to the laptop, the first to ftp://fip. pc. ibm. com / pub / pccbbs / mobiles / isbr01ww. exe download the IBM provided TP390/390e/390x series laptop battery refresh program. (2) Restart your computer, press F8 to enter boot menu and select safe DOS mode. (3) just download the files into the directory, the implementation of the battery refresh program isbr0lww, exe, reading the warning message, insert the floppy disk as required, and then press the Enter key to the implementation of the self-extracting operation. (4) boot floppy disk with this computer, the screen appears StartingPC-DOS. . . Message. (5) prompted unplug the AC power, the program will automatically be on the Ni-Mh battery discharge, discharge is completed, the system will automatically shut down. (6) The battery temperature is high at this time, should not immediately start, after the battery cool for a while, plug the AC power. (7) boot the computer with a floppy disk, the Autoexec. bat file will automatically run the refresh program, and ask the user whether to proceed. Select yes, press the Enter key. (8) At this point, refresh process began to refresh the battery, the process soon, when the return to DOS prompt A:> when that refresh is complete. (9) Shut down the computer, and charge the battery until the light turns green so far. (10) The above procedure is repeated three times to get the best results. In addition, many lithium battery pack failure is the result of a failure of energy-saving core, this phenomenon can not be avoided. Because each cell batteries can not be completely consistent with the nature, quality and use for a long time some little worse after the beginning of aging, and damaged the whole (in series) if the discharge curve. Interest and ability of the reader can try to open the battery pack, the multimeter's help, you can quickly find the damaged batteries (abnormal voltage). If conditions allow, according to the corresponding parameters of batteries can replace the qualified product.
[Edit this paragraph] laptop battery maintenance
1. When no external power supply situation, if the working conditions at the time being less than PCMCIA card slot, it is recommended to remove the card first to extend battery life. 2. Room temperature (20-30 degrees) for the best of the battery temperature, the temperature is too high or too low, the operating environment will reduce battery life. 3. Can provide a stable power supply in an environment using a laptop computer, remove the battery to extend battery life by not correct. On the ASUS laptop, when the full battery charge, the battery charging circuit will automatically shut down, Sony vgp-bps2a Battery



so the phenomenon of overcharging does not occur. 4. Proposal to conduct a three-month average battery power correction action. 5. To minimize the number of battery charge and discharge the battery life is directly related to the number of every single charge, the battery on a step forward to retirement. Suggest that you use an external power supply, 6. Use an external power supply should the battery removed. Some users often plug in the power supply several times a day, and notebook computers with batteries, do more damage to the battery. Because each time access is equivalent to an external power supply to charge the battery once the battery life shortened by a naturally. 7. Electricity charge and avoid exhaustion after the long charging time regardless of your notebook to use nickel-metal hydride or lithium electricity,Sony vgp-bps2b Battery to power must be exhausted after the full (capacity less than 1%), it is best to avoid the memory effect Methods. Lithium also have memory effect, but it is the memory effect than Ni-MH smaller Bale. 8. Caution normally used in peacetime to prevent exposure to prevent damp to prevent the erosion of chemical liquids, avoid contact with the metal battery contacts, etc. happen.
[Edit this section] the core notebook batteries
The current laptop battery is divided into 3 core, 4 core, 6 core, 8 core, 9 core, 12 cores. In brief, 4-cell battery life 2 hours, 6 core was 3 hours, and so on. Of course, the greater the number of cores, the longer the life, Hp dv4000 Battery of course, the higher the price, but stability will be less than the batteries to almost. Recommend the use of ordinary home users with their computer comes standard with the core number, such as 3-core, 4 core, because the main is in the home, a stable power supplySony vgp-bps2 Battery . Recommend the use of general office users 6 core and 8-cell battery, because the relatively long standby time point, make your office more convenient. If there is a higher mobile office requirements, we can consider 9-cell and 12 cell battery, this battery is not easy to carry too heavy, not 6 core and 8 core stability. In fact, core 6 core and 8 is sufficient, because the 6-core and 8 cores in your normal office use is up to 3 hours or more, if playing a game on the other.
