Repair Issues
Prevent Cosmetic Damage
The outside plastics of the PowerBook G3 Series computers
are vulnerable to scratches and finger marks from skin oil.
To prevent cosmetic damage to a customer’s PowerBook, do
not wear jewelry when handling the computer, and wear
gloves if you have them available. Wipe fingerprints from
the outside plastics with a damp cloth.
Install Microprocessor Board Securely
The microprocessor board can be partially inserted and the
computer will still function. However, over time, heat will
cause the microprocessor board to lose contact and can cause
the system to have intermittent problems such as no booting.
