CHAPTER 5: TROUBLESHOOTING

72

When troubleshooting your computer, remember the following safety guidelines:

Before touching any of the computer’s internal components, touch an unpainted

portion of the chassis. Doing so will safely discharge any static electricity, which could
damage your computer.
Turn off your computer and any connected peripherals.

Disconnect any peripherals from your computer.

Things to check:

Ensure that the AC adapter cable is properly connected between your computer and a

grounded, three-prong power outlet. Ensure that the power outlet is working.
Ensure the UPS or power strip is turned on (if applicable).

If your peripheral devices (e.g. keyboard, mouse, printer, etc.) are not working, ensure

that all connections are secure.
If any computer components were added or removed before the problem began, check

to see if you performed the installation or removal procedures properly.
If an error message appears on the screen, write down the exact error message prior to

calling Alienware Technical Support to aid in diagnosing and resolving your issue.
If an error occurs in a specific program, see the program’s documentation.
