Batteries and Power Management

Using Battery Power

54 Corporate Evaluator’s Guide

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 21.

• Plug in the AC adapter. See “Step 2: Connect AC power” on page 23.

• Install a charged secondary battery in the plug-in module bay. See “To use additional

batteries” on page 55.

Note

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

To recharge the battery

CAUTION

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.

• To recharge the main battery, plug the AC adapter into the computer.

• To recharge a secondary battery, plug the AC adapter into the computer and insert the

battery into the module bay.

The main battery will recharge first, then the secondary battery will recharge.

To get the longest operating time, wait until the battery’s charge is below 50% before

recharging, then charge it fully (100%). Charging can take up to approximately 3 hours.

You can continue working while the battery charges.

A fully charged battery can operate the computer for up to 4 hours, depending on your

computer’s model, power management settings, and level of use.
