To respond to a low-battery warning

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

Once the computer enters Hibernate mode in this way, you won’t be able to turn it on again until you restore power by doing one of the following:

•Replace the battery with a charged one—see “Step 1: Install the battery” on page 17.

•Plug in the AC adapter—see “Step 2: Connect AC power” on page 19.

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

To recharge the battery

The AC adapter is normally warm whenever plugged into an AC outlet. The computer is normally warm while recharging. Don’t recharge the computer in a briefcase or other confined space, or its battery could overheat.

•Plug the AC adapter into the computer.

To get the longest operating time, wait until the battery’s charge is below 50% before recharging, and then charge it fully (100%). Charging can take up to approximately 2 hours. If you continue working while the battery charges, the charging time may increase to 3 hours.

The operating time for a fully charged battery depends on your computer’s model, power management settings, and level of use.
