•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,
•Ensure the UPS or power strip is turned on (if applicable).
•If your peripheral devices (for example keyboard, mouse, printer, and so on) 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.
