Apple PowerBook G3 - Manual (Page 90)

90 Appendix
Caution
m If you have a problem with your computer and nothing in the computer manual solves
the problem, take the computer to your Apple-authorized dealer or service provider.
Attempting to repair the computer yourself may void the limited warranty.
m Do not move the computer when you can hear its hard disk spinning. When you put the
computer to sleep, wait until the screen is blank before moving the computer.
m Never force a connector into a port. Make sure that the connector matches the port and
that it’s right side up. If the connector and port do not join easily, they do not match.
m Do not use the computer in wet or dusty environments.
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,
unplug it, and remove the expansion bay modules 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.
m When using your PowerBook or when charging the battery, it is normal for the bottom of
the case to get warm. The bottom of the PowerBook case functions as a cooling surface
that transfers heat from inside the computer to the cooler air outside. The bottom of the
case is raised slightly to allow airflow that keeps the unit within normal operating
temperatures.
Important
m Use the computer only in environments where the temperature range is between
50°F/10°C and 95°F/35°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.
