When the battery is running out of power, both the battery and power indicators blink.
Keep the battery pack in the computer while it is directly connected to AC power. The battery pack continues to charge while you are using the
computer.
If the battery level falls to below 10%, you should either attach the AC adapter to recharge the battery or shut down your computer and insert a fully
charged battery.
You can extend battery life by changing the power management modes in the PowerPanel utility.
The battery pack supplied with your computer is a lithium ion battery and can be recharged 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 the battery life is nearly depleted, the battery indicator starts
flashing.

To remove the battery pack, proceed as follows:
1 Turn off the computer and close the cover.
2 Slide the lock lever (1) to the Unlock position.
3 Slide the release lever (2) to the Unlock position and slide the battery away from the computer.
You can remove the battery pack without turning off the computer when it is connected to the mains voltage (AC adapter).
Close the cover before you remove the battery pack.
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.
