Troubleshooting guidelines

As you troubleshoot your system, keep the following guidelines in mind:
Never remove the chassis cover while the computer is turned on.
Do not attempt to open the monitor. Even if the monitor power is
disconnected, stored energy within the monitor components can cause
bodily injury.
If a peripheral, such as the keyboard, mouse, drive, or printer does not
appear to work, verify that all connections are secure.
If an error message displays on the screen, write it down, word for word.
You may be asked about it when calling technical support.
Only qualified personnel should open the system for maintenance.
If you feel you are qualified to maintain the system yourself, make sure
you are properly grounded before opening the system chassis. Observe
the "Static electricity precautions" on page 13.
