Apple Macintosh PowerBook 190 Series - Manual (Page 13)

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 or with a Macintosh PowerBook 5300 series computer.
Adapters for other electronic devices (including other Macintosh
PowerBook models and other portable computers) may look similar, but
they may damage your computer.
