Charging a Battery Pack

A battery pack can be recharged wherever external power is available. These locations include the computer battery bay, MultiBay, an optional Battery Charger, and the docking base.

NOTE: Charging may be delayed if a battery pack is new, has not been used for two weeks or more, or is much warmer or cooler than a comfortable room temperature.

If you are charging the battery pack in the computer

External power can be supplied to the computer through the AC adapter, an optional docking base, or an optional Automobile Power Adapter/Charger.

NOTE: An optional Aircraft Power Adapter cannot be used to charge a battery pack.

The battery light, shown below, turns on while the battery pack is charging and turns off when the battery pack is fully charged.

To increase the accuracy of all battery charge displays

Allow a battery pack to discharge to the low-battery level through normal use before charging it.

When you charge a battery pack, charge it fully.

Before charging a new battery pack or a battery pack that has not been used for two weeks or more, calibrate the new battery pack or check the calibration on the unused battery pack.
