m Keep dirt and liquids away from the ports on the back panel, the keyboard,
and the trackpad. If you spill any food or liquid onto the computer, shut it
down immediately and unplug it before cleaning up the spill. Depending
on what you spilled and how much got into the computer, you may have to
bring the computer to an Apple-authorized service provider for cleaning.
m Do not touch the screen with any sharp or pointed objects.
m Use only the battery supplied with your computer, or an identical model.
Batteries designed for other portable computers may look similar, but they
may not work with your computer and may damage it.
m Use only the power adapter supplied with your computer, or an identical
model. Adapters designed for other electronic devices may not work with
your equipment and may damage it.
Important
m Use the computer only in environments where the temperature range is
between 50°F/10°C and 104°F/40°C.
m Do not expose the computer to very low (less than –13°F/–25°C) or very
high (more than 140°F/60°C) temperatures.
m If the computer has been in a cold place for several hours, let it warm up to
room temperature before you use it.
m Clean the computer’s outside surfaces with a damp (not wet) cloth. Clean
the screen with soft, lint-free paper or cloth and a mild glass cleaner. Do
not spray the glass cleaner directly onto the screen.
Caring for batteries
Always handle batteries carefully.
m Always put the battery cap on the battery when the battery is out of the
Macintosh PowerBook. The battery contacts should not be exposed when
the battery is out of the computer.
m Never get batteries wet.
m Do not short-circuit the battery terminals (that is, do not touch both
terminals with a metal object). Doing so may cause an explosion or a fire.
