will not close properly.
NOTE: The side of the battery opposite the warning label contains
a heat sensor that stops the flow of electricity if the battery
overheats.

opposite the AC adapter receptacle. Close and latch the cover. If
necessary, gently push the cover latch towards the AC adapter
receptacle until it latches.
