Diagnosing and recovering from problems 

Solving hardware and software problems

If the problem is:

Here's what to do:

Screen is black (no error 
code); beep during power 
on self-test (POST).

If you installed memory modules or adapter cards, make 
sure you installed them correctly. For instructions on 
installing memory modules on your system board, see 
“Installing memory modules” on page 9-9. For instructions 
on installing adapter cards in your system unit, see “Adding 
and removing adapter cards” on page 8-4. 

Error code (and 
description), more than 
one beep in self-test, or 
continuous beep occurs

If an error code or message appears, refer to the section 
“Error codes and messages” on page 10-17.

Computer turns off without 
warning

1. If mouse movement wakes the monitor, your monitor 

was in standby.

2. If computer power on light is blinking, your system is in 

Standby mode. Press the power on button to take the 
system out of Standby mode.

3. Make sure that the system unit and monitor power 

cords are securely plugged into electrical outlets.

4. Make sure that the cables are correctly and securely 

connected to the system unit.

5. Check for a blown fuse, tripped circuit breaker, or 

power failure.

6. Unplug the system unit power cord from the electrical 

outlet, wait 10 seconds, and then plug the power cord 
back into the electrical outlet. If the computer does not 
start immediately, push the power button on the 
system unit.

7. If you have added hardware inside the system unit, 

make sure the power cable connectors are securely 
attached.

Note: If any of these problems continue after taking the actions listed, see “Chapter 2. 
HelpWare support and services”  for information on obtaining service.
