Charging Battery Packs

The computer supports up to two battery packs: a primary battery pack located in the battery bay, and an optional external battery pack that can be attached to the computer.

When the computer is attached to an optional Mobile Expansion Unit (MEU), the system supports up to four battery packs: the primary and optional external battery packs on the computer and one battery pack in each of the MultiBays on the MEU.

If the computer and MEU are docked in an optional docking base, the system supports up to five battery packs: the primary and optional external battery packs on the computer, one battery pack in each of the MultiBays on the MEU, and one battery pack in the MultiBay on the docking base.

Multiple battery packs in the system charge and discharge in a preset sequence determined by location.

Charge sequence: 1—Computer battery bay

2—Optional computer external battery pack

3—Battery pack in the MultiBay of the optional docking base

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

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