Plugging in the computer
Plugging in the power adapter recharges the computer’s batteries. You should
plug in the power adapter in case the battery has drained during shipping or
storage.
When you are ready to begin:
1Plug one end of the power cord into the power adapter and the other end into a three-
hole grounded outlet or power strip.
WARNING
This equipment is intended to be electrically grounded. Your
Macintosh PowerBook is equipped with a three-wire grounding plug—
a plug that has a third (grounding) pin. This plug will fit only a
grounded AC outlet. This is a safety feature. If you are unable to insert
the plug into the outlet, contact a licensed electrician to replace the
outlet with a properly grounded outlet. Do not defeat the purpose of the
grounding plug!
WARNING
Use only the power adapter that came with your Macintosh
PowerBook. Adapters for other electronic devices (including other
portable computers) may look similar, but they may damage your
computer.
