Troubleshooting the Keyboard and Mouse
If the system reports an error message that includes misc/kbd
or misc/mouse, the problem is in the keyboard, mouse,
keyboard-mouse cable, or system module. Troubleshoot these
items as follows:
1.
Make sure that the keyboard and mouse are attached
correctly to the keyboard-mouse cable and that the
keyboard-mouse cable is attached correctly to the system
unit.
2.
Repeat the power-up self-test by turning the system unit
power off and then on again.
3.
If the power-up self-test still returns the error message
misc/kbd or misc/mouse, replace the keyboard or the
mouse.
If the error message is misc/kbd, replace the keyboard.
If the error message is misc/mouse, replace the mouse.
4.
If the power-up self-test still returns the error message
misc/kbd or misc/mouse after you replace the problem
item, replace the keyboard-mouse cable. Then repeat the
power-up self-test.
5.
If the power-up self-test returns message code misc/kbd
or misc/mouse after you replace the keyboard, mouse, and
keyboard-mouse cable, replace the system module and
chassis. Refer to ‘‘Replacing a System Module and Chassis’’
earlier in this chapter for directions.
