Removing the Main Battery
One or two plug-in modules can be inserted in the module bays in the expansion base. The computer
itself has no module bays.
Slide the battery's release latch, then lift the battery out of its compartment.
Insert the front end of the battery into the battery compartment, then press the back end in until it
clicks into place.
