Laptop battery using secret tips
Computer battery is the basis for mobile applications, but also a kind of consumables. Many users claim that their VGP-BPS9 VGP-BPL8 batteries for six months on the charge could not afford electricity, but actually, if you pay attention to the daily use of maintenance battery, maintenance can significantly extend their useful life.
First, the establishment of appropriate solution for energy management.
1. The establishment of the appropriate solution for energy management not only to meet the needs of daily use, but also extend battery life. New program to power management, solutions management first plant to be named, to facilitate future management and switching. And then need to set the processor speed and brightness of the LCD, so the extra system resources, not much lower frequency of the processor can be used to reduce power consumption and improve battery life. Powered by battery, it can appropriately reduce the brightness of the LCD to save power. Then go with the hardware (disk drives, LCD screens, etc.) and the system hang time. Here there is no fixed model set-up time should be based on their actual needs.
To support the effective management of power solutions for battery management, it should be enough power to set the alarm time. Because the characteristics of lithium-ion batteries to extend battery life, the remaining capacity may be less than 5%, or go a long battery life will be significantly reduced. It is preferable to set the battery discharge to 6% to 7% of the alarm, the alarm can be set to the text, it will not affect others. Alarm after the system response can be configured in standby or hibernation, the system shutdown after the timely replacement of batteries or recharge the battery, to avoid excessive discharge and shorten battery life.

2, set the threshold of perception
With the increasing number of charge cycles, battery capacity would be gradually reduced until the end of life, giving reasonable cost thresholds may actually prolong the life of the battery. Many laptop manufacturers to develop third party software power management function is provided for adjusting the threshold of support. The so-called threshold value is a charge to allow battery charging power range, usually a percentage of unit power from the battery.
Threshold settings of care in general there are three options: Always load, the load is automatically set thresholds and custom. Has always been as long as the battery charge is below the battery Jiugei is suitable for users who often use battery-powered, if you do not use batteries do not choose, otherwise it will shorten the life of battery. Load threshold is set automatically by the software power management, according to the actual capacity of the battery charge a reasonable calculation of the threshold level is not high for laptops with a friend. Customized by the user to define load levels, suitable for notebook users who are more familiar. Function using the author’s experience, the battery “health” of the case, the load threshold is set at 30% ~ 80% is appropriate (that is, less than 30 % of charge remaining capacity, remaining capacity is greater than 80% free) in the case of aging and the battery is charging threshold set at 40% ~ 70% is appropriate.

3, the calibration of the battery
Some software power management feature provides a calibration of the battery, calibrate the battery on a regular basis can make the chip Battery Management registered in battery capacity closer to actual capacity achieve the goal of extending the battery life. Before the battery in the calibration must be closed other applications and documents, and an AC power adapter externally. And then open the calibration function of the battery, the software will do the depth of battery discharge and then full power (some laptop batteries included in the calibration procedures of the BIOS, the need for setting implement the BIOS).
Without calibration function of the battery for laptops, we can manually correct the battery. In the case of full power, first close all applications, disable the screen saver and hibernation system, function monitoring. Then close the LCD screen and optical drive, disable the wireless adapter, then unplug the power adapter. Do nothing until the 367759-001 F2024A laptop automatically closed. And then re-external AC adapter until the battery is fully charged the battery after completion of the operation manual calibration.
The already significant degradation of the battery must also take corrective action if the battery capacity decreased after adjustment, we can not continue to be calibrated the battery. A significant deterioration of the battery frequent calibration will significantly shorten the battery life of the battery or even a direct consequence of scrap battery. For normal use the batteries, a battery can be adjusted up to three months, otherwise, would damage the battery.
4, the battery not use should be maintenance
Most of the time many users are using the AC power supply to their books, very few used batteries. Some users may think that does not use batteries, the batteries’ longevity. In fact, battery production will begin after the aging, the battery capacity remaining is too high and long term does not discharge the battery life will be shortened. Which are not commonly used in batteries, can charge its battery to 30% ~ 60%, then the battery with waterproof waxed paper wrapped and placed in direct sunlight can be ventilated and cool. And every six months is also required for battery charging and discharging time, which can protect A1185 A1045 battery life.
