CHAPTER 5: TROUBLESHOOTING

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 o your computer and any connected peripherals. •

Disconnect any peripherals from your computer. •

ings 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 specic program, see the program’s documentation. •
