To Respond to a Low-Battery Warning

The notebook automatically alerts you when the battery power drops to a critically low level. The notebook first emits a high-pitched beep or displays a warning message. Then, if you do not restore power within a short time, the notebook goes into Hibernation.

After the notebook enters Hibernation in this way, you will not be able to turn it on again until you restore power by using one of the following procedures:

■Replace the battery pack with a charged one.

■Plug in the AC adapter.

✎If you plug in the AC adapter, you can continue to work while your battery pack recharges.

To Recharge the Battery Pack

ÄCAUTION: The AC adapter is normally warm when plugged into an AC outlet. The notebook is normally warm while recharging. Do not recharge the notebook in a briefcase or other confined space, or the battery pack could overheat.

»Plug the AC adapter into the notebook.

Charging can take several hours. If you continue working while the battery pack charges, the charging time may increase.

The operating time for a fully charged battery pack depends on the notebook model, power management settings, and level of use.
