Note CAUTION Traveling with Your Computer Using Battery Power To respond to a low-battery warning The computer automatically alerts you when the battery power drops to a critically low level. If you do not restore power within a short time, the computer then goes into Hibernate mode. Once the computer enters Hibernate mode, 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. • Install a charged secondary battery in one of the expansion base's plug-in module bays-see "To add additional batteries" on page 55. 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. • To recharge the main battery, plug the AC adapter into the computer, or dock the computer and plug the AC adapter into the dock. • To recharge a secondary battery, plug the AC adapter into the expansion base and insert the battery. Batteries charge in this order: main battery, secondary battery in the left module bay, secondary battery in the right module bay. 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 2 hours. You can continue working while the battery charges. A fully charged battery can operate the computer for up to approximately 3 hours, depending on your computer's model, power management settings, and level of use. 54 Corporate Evaluator's Guide
