Hi @Dylan76 ,

Welcome to the HP Support Community.  

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

If your HP 22-df0003w All-in-One PC is receiving power but not turning on properly, there are several troubleshooting steps you can take to identify and potentially resolve the issue. Here are steps you can follow:

Check Power Connections:

• Make sure that the power cable is securely connected to both the wall outlet and the power input on the back of the computer.
• Verify that the power outlet is working by testing it with another device.

External Peripherals:

• Disconnect all external devices and peripherals, including printers, external drives, and USB devices.
• Try turning on the computer without any external devices connected.

Hard Reset:

• Perform a hard reset by shutting down the computer and unplugging the power cable.
• Press and hold the power button for about 15 seconds to discharge residual electrical charge.
• Reconnect the power cable and try turning on the computer.

Display Issues:

• Check if the display brightness is set too low. Press the brightness adjustment keys on your keyboard.
• Connect an external monitor to your All-in-One PC to check if the issue is with the display. If the external monitor works, the problem may be with the built-in display.

BIOS/UEFI Update:

• Check if there are any available BIOS/UEFI updates for your computer on the HP support website.

Memory and Hardware Checks:

• Reseat the RAM modules. Turn off the computer, disconnect the power, and reseat the RAM modules in their slots.
• Ensure that all internal hardware components are properly connected.

Diagnostic LEDs:

• Some All-in-One PCs have diagnostic LEDs on the back or bottom. Check if any of these LEDs provide information about the status of the system.

I hope this helps. 

Take care and have a good day.-
