The HP All-in-One will not turn on
Cause: The HP All-in-One is not properly connected to a power supply.
Solution:
• Make sure the power cord is firmly connected to both the HP All-in-One and the
power source. Plug the power cord into a grounded power outlet, surge protector,
or power strip.
1 Power connection
2 Grounded power outlet
• 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.
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
