Printer won't turn on, tried unplugging and plugging into a different working outlet and still no power. Maybe need a new power cord? Printer completely broken?

Hi @Stattb,

Welcome to The HP Support Community.  

Thank you for posting your query, I will be glad to help you.

I understand you are facing an issue with your HP Officejet 4635 e-All-in-One Printer won’t turn on at all, follow these steps to troubleshoot the issue:

1. Check the Power Source

• Try plugging the printer into a different wall outlet that you know is working.
• Avoid using power strips or surge protectors; plug directly into the wall.
• Test another device (like a lamp or phone charger) in the same outlet to ensure it’s working.

2. Inspect the Power Cord & Adapter

• Check for damage: Look for any frayed wires, kinks, or cuts in the power cord.
• Ensure a secure connection: Firmly plug the power cord into both the printer and the wall outlet.
• If you have another compatible HP power adapter, try using it.

3. Perform a Power Reset

1. Unplug the power cord from the printer and the wall outlet.
2. Wait at least 60 seconds.
3. Press and hold the printer’s power button for 15 seconds (if applicable).
4. Plug the power cord back into the wall outlet first, then into the printer.
5. Try turning the printer on.

4. Check for a Faulty Power Module (Brick)

• If your printer has a power module (a brick in the middle of the cord), check if the LED indicator light on it is lit when plugged in.
• If there’s no light, the power supply might be faulty, and you may need a replacement.

5. Try a Different Power Cord

• The HP Officejet 4635 typically uses a 32V power adapter (check your power supply label).
• If you have another HP printer with the same power cord, try swapping it to see if the printer turns on.

6. Check for Internal Hardware Issues

• If none of the above steps work, the printer’s internal power supply or mainboard could be damaged.
• Unfortunately, repair costs might exceed the value of replacing the printer.

I hope this helps. 

Take care and have a good day.
