Can you use the laptop battery correctly?
Are you using laptop? how many using ways do you have? How should we save the battery from Long-term using? It is less important in surface, but it does affect the Battery's life. Do you want to extend it? follow me and let us learn how to use the battery!
1, how to use the battery
Most laptops are equipped with automatic functions of reduced frequency, this maximizes the battery's life. People who use the Celeron may have questions, "my laptop does not have this feature, does it can't save power? In fact, CPU power consumption is only a part of the whole consumption, the consumption order should be : LCD> CPU > Graphics> Wireless LAN> CPU fan. In other words, we can start from the other side to minimizing the electricity consumption.
There is a power management option in Windows XP Control Panel, at the "power scheme", it is the most reasonable to set the LCD screen about 10 minutes. As for the hard disk, it will be more than 15 minutes. Instant startup need a certain power much less to frequently start and stop on the hard disk, which damages a lot. Of course, you can also turn off the screen manually, most of the books can achieve that by fn + F3 function key.
If you want to further save power, you need to adjust the running system, a Windows XP can't do this. With Thinkpad, for example, most of the books have built-in battery management software, general books will provide eight screen brightness adjustment, although the state can get the brightest best visual effect, but it is extremely power-consumption, so the brightness with the lower six or seven when edit a document or some other common application is ok. At the same time, CPU can be set to the best battery performance, and CPU fan running status be set to "balanced" is more reasonable.
Second, the correct charging method
when people use the battery, many of them start charging when the power capacity is below 100%. however, that would have the power Zong Jiasuxiangdi lithium capacity, long down, the short battery life on a lot, but also greatly Suduan Shouming . Therefore, the proposal will be limited to less than 10% of the charge re-charge, should also be careful not to set too low, such as the use to only about 3% charge left, this is not scientific. Insufficient power to set the alarm must be generally less than 10% of the alarm as well, less than 3% of the serious alarm means that the battery is insufficient to support the boot into the system the next time. Many battery management software is less than 96% of the default start charging, it will damage the battery charge, so be sure to change this setting. In addition, the best off charging the battery so you can play the role of conservation.
Third, discharge necessary?
If the books of the battery for a long time to reduce power consumption significantly, the depth of discharge can try to "save" it. This is a "dead horse a living horse doctors" approach, not a last resort, better not to do so. Discharge the simplest way is to constantly run the program, less than 3% of electricity to restart the books after running into the BIOS vacant until the automatic power-off date. Then the depth of charge, charging time to reach eight hours, but not more than 12 hours, so you can restore some power to lithium batteries.
