74 Appendix B Safety, Use, and Care Information
When using your PowerBook or when charging the battery, it is normal for the bottom
of the case to get warm. For prolonged use, place your PowerBook on a flat, stable
surface. 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. In addition, the computer vents warm air from the back of the case.
Carrying Your PowerBook
If you carry your PowerBook in a bag or briefcase, make sure that there are no loose
items (such as paper clips or coins) that could accidentally get inside the computer
through an opening such as the optical drive slot.
Storing Your PowerBook
If you are going to store your PowerBook for an extended period of time, do one of the
following to prevent your PowerBook battery from becoming completely depleted:
ÂKeep the power adapter connected.
ÂFully charge your PowerBook battery before storing the computer.
ÂFully charge and then remove your PowerBook battery when storing your computer
(especially important when storing your computer for longer than 5 months).
Cleaning Your PowerBook
Follow these general rules when cleaning the outside of your computer and its
components:
ÂShut down your PowerBook and remove the battery.
ÂUse a damp, soft, lint-free cloth to clean the computer’s exterior. Avoid getting
moisture in any openings. Do not spray liquid directly on the computer.
ÂDon’t use aerosol sprays, solvents, or abrasives.
Cleaning Your PowerBook Display
To clean your PowerBook screen, do the following:
ÂShut down your PowerBook and remove the battery.
ÂDampen a clean, soft, lint-free cloth or paper with water only and wipe the screen.
Do not spray liquid directly on the screen.
Warning: Do not place your PowerBook on a pillow or other soft material when it is
on, as the material may block the airflow vents, in particular the rear vents, and cause
the computer to overheat. Never place anything over your keyboard before closing
the display. This can cause your computer to cycle on and off which may create
excessive heat and drain your battery. Never turn on your computer unless all of its
internal and external parts are in place. Operating the computer when it is open or
missing parts can be dangerous and can damage your computer.
