Laptop Battery Maintenance Guide
The battery is a consumable and has a limited life span, most manufacturers F2299A warranty for the laptop battery time ranging from three months to one year, Dell is to follow industry standards to provide one-year limited warranty. For the battery, the correct use and proper storage, is the ability to significantly extend the battery life of notebook computers.
1, the battery used in a few attention points.
1. Why use an external power supply, you can win without the battery?
(1) The motherboard has a chip to prevent overcharging. When the battery charge to 100%, the charge control chips (FET) will stop charging the F3172A battery. We do not have to worry about damage to the battery.
(2) The battery connections to avoid the BIOS information is lost.
(3) to prevent a sudden power loss of data.
2. To prevent exposure to prevent damp to prevent the erosion of chemical liquids, avoid contact with metal objects touch the battery short-circuit, etc. happen.
3. A long time without notebook computers, how to preserve the battery?
We will face a period of time does not use a notebook, the battery should be full of electricity saved, or the need to put end to save electricity?
Optical long-term preservation Pavilion ZT1000 would put batteries lose their activity, and even lead to the control circuit protection self-locking can not re-use, full of electricity will bring long-term preservation security risks, the best preservation method is to use to about 40% of capacity and then save the in a cool dry place, about 20 degrees Celsius is the ideal storage temperature. Of course, best to take the battery out every month to use them once, both to ensure the battery a good state of preservation, but also alienating the loss of damage to the battery power completely.
How do I see Dell battery power consumption? (In D610 battery as an example)
Remove the battery, according to the battery symbol, you can see five of the battery status light. Two consecutive bright, representing 40% of the Pavilion XZ200 electricity. On behalf of the whole light power is sufficient, if the 135 bright, that is, the battery is damaged.
Second, how to extend laptop battery as much as possible working time?
(1) reduce the screen brightness. How to adjust the brightness of the use of laptop batteries, boot press F2, enter BIOS to adjust the Video in the Brightness item.
Or use fn + down / up key combination to Pavilion ZT1100 quickly adjust the brightness.
Specific old BIOS please refer to:

(2) Open the CPU speedstep feature, you can significantly extend battery run-time; Cpu's speedstep function of BIOS is enabled by default. When using batteries, cpu will automatically down-to use, in order to achieve energy-saving purposes. If not enabled, please switch on press F2, enter BIOS found in Performance, is set Speedstep Enable to Enabled. (Old BIOS is the Alt + P to the sixth page, modify the intel speedstep)
(3) The use of standby, sleep and other functions. As a long time without a computer, allowing notebook standby or hibernate, saving electricity Omnibook XT1000 also extended the life of notebook computers. (Tips: Make sure video card drivers installed successfully, the power management options can be set.)
In the WINDOWS proceedings against power management settings, we generally can be set to "Portable / Laptop" (Portable / Laptop).
At the same time suggest that you will use the notebook computer batteries, turn off the monitor wait time is set to 5 minutes, so that when we do not operate within a certain period of time laptops, it will direct black state, so other than the screen saver is running to be more provinces electricity.
(4) When using the laptop battery as far as possible off the Omnibook XT1500 wireless, Bluetooth and infrared terminal
