Troubleshooting
If you encounter a hardware problem, we recommend that you
review the following suggestions before calling for service:
General failure
Are all cables securely plugged?
Are all system components and peripherals turned on?
Is the system main power switch on?
Is the power outlet burned out? You may check this by
plugging in and turning on some other piece of
equipment.
Are any cables damaged? Are they properly routed and
coiled? Entwined cables may cause signal interference.
Front panel light doesn't work
After turning off the computer, check inside the system
unit and make sure that the front panel LED connector
for the LED that is not working is correctly plugged.
Refer to "Jumpers and Connectors" on page 27 to identify
the proper LED connector.
"Garbage" or nothing appears on the screen
Is the monitor turned on? Is the screen brightness
adjusted properly?
Warning! Never open the monitor case. The CRT monitor retains very high
voltage levels even after the power is turned off. Refer all monitor service to
qualified service technicians.
Keyboard is dead
Is the keyboard cable plugged in? Turn off the system
and plug in the keyboard.
Caution: Do not plug or unplug the keyboard while the power is on.
