Plug in the power adapter or use the recharger.

locking device and security cable. See your authorized Apple

Service and support
If the PowerBook malfunctions or is damaged
If your computer is malfunctioning but does not appear to be
physically damaged, shut it down (and leave the power adapter

If you know or suspect that your computer is physically damaged,
disconnect the power adapter, remove the battery, and do not use
