Laptop, are you using it? That you use the laptop batteries has mastered how much? Long-term use to connect the power of books-how to keep the battery good books do? Seem less important issue, in fact affecting the battery books life, want to use books longer so? then let us learn what battery to use bar!
1, the battery use of the program
Most notebooks have the automatic down-conversion function, so that the benefits of the books is to maximize battery charger battery life. Many people who use the Celeron may have questions about books, our books do not have this feature, is not naturally less power out? CPU is only one part of the cost of electricity, in fact, the order should be like electricity: LCD> CPU (speed) “graphics” Wireless LAN> CPU fan. In other words, in addition to CPU, we can also start from other areas, the maximum reduction in power consumption.
In the Windows XP Control Panel, there is a power management option, the “power scheme”, the set up LCD screen is idle about 10 minutes off the most reasonable, while the hard disk will have to set more than 15 minutes more appropriate. The hard disk to start the moment requires a certain power did not say, frequent start and stop the damage to the hard drive is quite big. Of course, you can also manually turn off the screen, most of the books through fn function key + F3 to achieve.
Set LCD, hard drive shut down time, if you want to further conserve Dell Inspiron 1501 battery power, but also need to adjust the operation of the system state, it is not a Windows XP can do. With Thinkpad, for example, most of the books have a built-in battery management software, general books will provide eight screen brightness adjustment, although the brightest state of access to the best visual effects, but it is very, very power-hungry, so , edit a document or some other general applications to adjust the screen brightness to a lower 6 or 7 the most appropriate. At the same time, CPU can also set the best Dell Inspiron 1520 battery performance, CPU fan running status set to “balanced” more reasonable.
Some low-priced books there is no battery management software (because there is no built-in power management chip), but you can use a common battery monitoring software to manage the battery.
Sample used in the T43, is running at full speed when playing DVD discs, the battery usage time is only 2 hours 37 minutes, while the optimized program can be achieved when using a long 3 hours 17 minutes or so, raise obvious. Set the screen brightness, CPU speed, fan speed.
2, the correct charging method
Many people use books the hp pavilion battery , I saw that the power began to charge less than 100%, but this would accelerate the reduction of the total capacity of lithium battery power for a long time go, battery life much shorter time, but also greatly shortened life expectancy . It is therefore recommended to limit the charge less than 10% re-charge, and be mindful not to set too low, such as the use to only about 3% charge left, which is not enough science. Power shortages must be set up when the alarm is generally less than 10% of the police as well, less than 3% of the serious alarm means that the battery has been insufficient to support the boot into the system the next time. A lot of battery management software is less than 96% of the default start charging, so charge will damage the battery, so be sure to change this setting. In addition, it is best off charge, so you can play a role in conservation of the battery.
3, discharge necessary?
If the books for a very long battery power considerably reduced, the depth of discharge can try to “save” it. This is a “dead horse like a living horse medicine” approach, less than a last resort, better not to do so. Discharge The easiest way is to constantly run the program, less than 3% in electricity to restart the books into the BIOS to run the vacancy until the automatic power-off date. Then the depth of charge, charging time to reach eight hours, but not more than 12 hours, which would allow Li-ion battery to restore some power.
