The HP All-in-One will not turn on

•If you are using a power strip, make sure the power strip is on. Or, try plugging the HP All- in-One directly into a power outlet.

•Test the power outlet to make sure it is working. Plug in an appliance that you know works, and see if the appliance has power. If not, then there might be a problem with the power outlet.

•If you plugged the HP All-in-One into a switched outlet, make sure the switch is on. If it is switched to on but still does not work, then there might be a problem with the power outlet.

Cause: You pressed the On button too quickly.

Solution: The HP All-in-One might not respond if you press the On button too quickly. Press the On button once. It might take a few seconds for the HP All-in-One to turn on. If you press the On button again during this time, you might turn the device off.
