Apple PowerBook (5300 Series) - Manual (Page 14)

Plugging in the computer
Plugging in the power adapter recharges the computer’s battery. You should
plug in the power adapter in case the battery has drained during shipping or
storage.
When you are ready to begin, follow these steps:
1 Plug 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. The
power adapter that came with 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 computer. Adapters for other electronic devices (including
other Macintosh PowerBook models and other portable computers) may
look similar, but they may damage your computer.
