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 4 hours,
depending on your computer's model, power management settings, and level of use.
