Write down the computer serial number, product ID number, and monitor serial number before calling.

Spend time troubleshooting the problem with the service technician.

Remove any hardware that was recently added to your system.

Remove any software that was recently installed.

Restore the system from the Recovery Disc Set that you created or restore the system to its original factory condition in System Software Requirement Disks (SSRD).

CAUTION: Restoring the system will erase all data on the hard drive. Be sure to back up all data files before running the restore process.

NOTE: For sales information and warranty upgrades (Care Packs), call your local authorized service provider or dealer.

Helpful Hints

If you encounter problems with the computer, monitor, or software, see the following list of general suggestions before taking further action:

Check that the computer and monitor are plugged into a working electrical outlet.

Check that the voltage select switch (some models) is set to the appropriate voltage for your region (115V or 230V).

Check that the computer is turned on and the green power light is on.

Check that the monitor is turned on and the green monitor light is on.

Check the Power LED on the front of the computer to see if it is flashing red. The flashing lights are error codes that will help you diagnose the problem. Refer to Appendix A, POST Error Messages on page 127 for more information.

Turn up the brightness and contrast controls of the monitor if the monitor is dim.

Press and hold any key. If the system beeps, then the keyboard should be operating correctly.

Check all cable connections for loose connections or incorrect connections.
