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
