The battery pack supplied with your computer is a lithium ion battery and can be recharged
at any time. Charging a partially discharged battery does not affect battery life.
The battery indicator light is on while you use the battery pack as a power source. When
battery life is nearly depleted, the battery indicator starts flashing.
For some software applications and some peripheral devices, your computer may not enter
System Hibernation mode when the battery life is low. To avoid loss of data when using
battery power, you should save your data frequently and manually activate a power
management mode, such as System Suspend or System Hibernation.
✍
You may lose data if you remove the battery pack while the computer is on and not
connected to the AC adapter or if you remove the battery while the computer is in System
Suspend mode.
You can remove the battery pack without turning the off the computer when your computer
is connected to the AC adapter. Before inserting or removing the battery pack, close the
cover.
