Maintenance and Troubleshooting 4-3
Keyboard Cleaning
When necessary, inspect and clean the inside of the keyboard as follows:
1.
Remove the six screws holding the keyboard enclosure together.
NOTE:
The keyboard and cable together are con-
sidered a whole-unit, field-replaceable
assembly. Therefore, disassembly of the keyboard
is necessary only when cleaning the inside.
2.
Separate the two halves of the enclosure. Clean the enclosure and keys with a damp
cloth. A small, soft-bristle brush may be used to clean between the keys. Do not wet
or dampen the keyboard's printed circuit board (PCB). If the PCB
accidentally gets wet, thoroughly dry it before reattaching the keyboard to the system
unit.
Mouse Cleaning
Under normal conditions, the mouse has a self-cleaning mechanism that prevents a buildup of
dust or lint around the mouse ball and tracking mechanism. Periodically, however, the mouse
ball must be cleaned. Use the following procedure to clean the mouse.
1.
Unplug the mouse from the system.
2.
Turn the mouse upside down and locate the mouse ball cover (see
Figure Section 4-
1
).
3.
Turn the ball cover counterclockwise and remove the cover.
