• 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 minutes 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.
CAUTION:
Unplug the HP All-in-One from the power outlet and contact HP. Go to:
support. If prompted, choose your country/region, and then click Contact HP for information
on calling for technical support.
