Battery Packs

■Discharge sequence:

1—Battery pack in the right MultiBay of the optional Mobile Expansion Unit

2—Battery pack in the left MultiBay of the optional Mobile Expansion Unit

3—Optional computer external battery pack 4—Computer battery bay

✎A battery pack inserted into the MultiBay of the optional docking base can be charged but cannot be used to provide battery power to the system.

Using a New Battery Pack

Charge the battery pack in the computer’s battery bay while connected to an external power source or while attached to the Mobile Expansion Unit.

A new battery pack should be fully charged before it is used for the first time. The battery pack will work without being fully charged, but the battery gauge will not show an accurate charge until the battery pack receives its first full charge.
