● 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 grounded 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.
