Troubleshooting Procedures
1. Press the power button to turn the computer off.
Make sure the power cord is not damaged and is the correct type for your geographical area.
Make sure it is plugged in firmly on both ends. If there is a problem with the cord, correct it and
go to "Procedure #3: Powerup/Reset." If the computer comes up correctly, your problem is fixed.
2. Check the electrical source by plugging something else into the outlet, such as a lamp. If there is
a problem with the outlet, correct it and go to "Procedure #3: Powerup/Reset." If the computer
comes up correctly, your problem is fixed.
3. Check to make sure your computer is configured for the proper input voltage by checking to see
the voltage setting is correct on the voltage switch on the back panel of your computer.
Caution: If you have operated the computer with the improper input voltage, you may
have damaged the computer.
If your computer is configured incorrectly, change the voltage switch to the proper setting, and
perform "Procedure #3: Powerup/Reset" only ONCE. If the computer does not come up
correctly, shut off the power and contact your VAR for help; stop. If it does, your problem is
fixed.
If your computer is configured correctly, proceed:
4. If the voltage configuration is correct, and the power cord is OK and in place correctly, but the
power light is still not on, call your VAR for help. Stop.
B. OK, the power light is on. Is the run light on? If so, skip to Step C.
1. If the run light is off, then perform "Procedure #2: Check the System Status Codes." If the
procedure does not find and correct any problems, proceed.
2. Perform "Procedure #3: Powerup/Reset," ONCE. If that procedure does not correct the problem,
proceed.
3. Perform "Procedure #5: Self Test." Call your VAR with the results of your self test and ask for
help. Stop.
C. The power light and the run light are both on. Check the front panel display, after booting
successfully the status LED will display a 0 and the run light should be on. If a status code appears
on the front panel display and the computer does not boot, compare the status code with the status
codes shown in Procedure #2.
1. Note: If the memory light is on more than once in a great while, contact your VAR—you
probably have memory problems.
The memory light is actually a "1" in front of the two-digit status code on the front panel. When
you see a 1 in this position, it indicates a parity error condition.
If the memory light is on, perform "Procedure #3: Powerup/Reset" ONCE. If that procedure does
not clear the memory light, proceed.
2. Perform "Procedure #5: Self Test." Call your VAR with the results of the self test and ask for
help. Stop.
