Maintaining the System
This chapter describes cleaning the system, replacing system parts, and
reprogramming the flash EPROM with a new Basic Input/Output System
(BIOS).
Cleaning the System
Follow these guidelines for cleaning the workstation.
CAUTION
Power off the workstation before cleaning the exterior surfaces, mouse,
and keyboard. Do not clean the CD-ROM drive.
Exterior Surfaces
Use a mild cleaning detergent and a clean cloth to clean the monitor screen
and the exterior surfaces of the base unit.
Mouse
On the bottom of the mouse, a retaining ring holds the tracking ball in place.
To clean the mouse, remove the retaining ring and turn the mouse over; the
tracking ball will fall out. Blow gently into the opening. Clean the tracking
ball and rollers with a cotton swab and alcohol. Replace the tracking ball
and the retaining ring.
Keyboard
Dust the keyboard with a dry cloth. Aerosol cleaners are commercially
available to remove the dust between the keys of the keyboard. Never allow
moisture on the keyboard or the surface beneath the keys.
