Faulty power cords and connections are an uncommon but possible cause of a printer not turning on. Before suspecting a cord failure, ensure that there is power to the wall outlet and there are no conditions preventing the printer from turning on. Testing by substitution can confirm if a cord connection is the problem.
Turn the printer off then back on. If the issue persists, turn the printer off, unplug the power cord and then wait at least three minutes before plugging the power cord back in and turning the printer back on. If the issue persists, ensure the product is running the latest firmware available from HP.com.
Printer sleep mode

Check that the printer does not have sleep mode enabled: Go to Control Panel > Devices and Printers. Right-click the printer in question, then select Printer Preferences. Look for an option to disable sleep or time-out mode.

Battery Troubles:

If your HP laptop has a removable battery, remove it and reinsert it after a few seconds. Sometimes, a faulty connection can cause the power light to blink. If you can access a spare battery, try swapping it to see if the issue persists.

A blinking Power light might indicate a `Fatal Error,” that requires a printer reset. Follow these steps to reset the printer. Without turning off the printer, disconnect the power cord from the rear of the printer. Wait 30 seconds, and then reconnect the power cord to the rear of the printer.

ANSWER : I’ve gone out on service calls with this problem. One had a breaker popped. The other was an engineering firm. If it was plugged in and they said “We’re engineers”.

Printer will not power up
ANSWER : The switch is actually just a plastic piece that moves a metal rod that actuates the real switch in the back. I’ve seen where the rod pops out. Can you hear a click when you rock the switch back and forth? Otherwise, it would be a bad controller board. That is the large board at the bottom of the printer. Never seen one do that in that model.
