CHAPTER 5: TROUBLESHOOTING
74
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.
