Charging Laptop Battery
When you connect the computer with the battery installed to an electrical
outlet, the computer checks the battery charge and temperature. If
necessary, the AC adapter charges the battery and maintains the battery
charge.
NOTE:
The AC adapter charges the battery even when the computer
is turned off. The internal circuitry of the battery prevents the battery
from overcharging.
If the battery is hot from being used in your computer or being in a
hot environment, the battery may not charge when you connect the
computer to an electrical outlet.
NOTE:
You can operate your computer while the battery is charging.

Improving the Battery Performance
The operating time of a battery, which is the time the battery can hold a
charge, varies depending on how you use your laptop computer.
The operating time of your battery significantly reduces if you use:
• Optical drives.
• Wireless communications devices, ExpressCards, media cards, or USB
devices.
• High-brightness display settings, 3D screen savers, or other
power-intensive programs like complex 3D graphics applications
and games.
You can improve the battery performance by:
• Operating the computer on AC power when possible. Battery life
reduces with the number of times the battery is discharged and
recharged.
• Configuring the power management settings using Microsoft Windows
Power Options to optimize your computer’s power usage (see
Power
Management )
.
• Enabling the Sleep/Standby and Hibernation features of your
computer.
NOTE: The life of the battery decreases over time depending on how
often the battery is used and the conditions under which it is used.
