Hi @Togs1,

Welcome to The HP Support Community.  

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

I understand the power LED on your HP DeskJet Ink Advantage Ultra 4729 is not lit and other LEDs are glowing steadily, it could indicate a power supply or internal issue. 

Here’s what you can try to troubleshoot the problem:

Check the Power Connection:

• Ensure the power cable is securely connected to both the printer and the power outlet.
• Try plugging the printer into a different power outlet.

Inspect the Power Cable:

• Check the power cable for any visible damage. If you see any fraying or cuts, you may need to replace the cable.

Perform a Hard Reset:

• Disconnect the power cable from the printer and wait for at least 60 seconds.
• Plug the power cable back in and try turning the printer on again.

Check for Electrical Issues:

• If other devices work when plugged into the same outlet, the issue is likely with the printer. If the outlet is faulty, try a different one.

Look for Error Messages:

• If other LEDs are on, check if they are flashing in a particular pattern. Refer to the printer’s manual or HP's support website for what the LED patterns mean.

Check for Internal Issues:

• If possible, check inside the printer for any obvious signs of damage or obstruction. However, avoid opening the printer if it's under warranty or if you're unsure.
