Hi @Lindsey269,

Welcome to the HP Support Community.
 

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

If your HP Pavilion All-In-One PC is not turning on and is showing a message to check the HDMI cable, there are a few troubleshooting steps you can follow:
 

Check Power Supply:
 

• Ensure that the power cable is properly connected to the PC and the power outlet.
• Verify that the power outlet is working by connecting another device to it.

Check Power Button:
 

• Make sure the power button is not stuck and is functioning properly.

Perform a Power Reset:
 

• Disconnect the power cable from the back of the PC.
• Press and hold the power button for about 15 seconds to drain any residual power.
• Reconnect the power cable and try turning on the PC again.

Detach External Devices:
 

• Unplug any external devices connected to the PC (except the keyboard and mouse) and attempt to power it on.

Check for Status Lights:
 

• Look for any LED lights when you attempt to turn the PC on. This can give clues about the power status.
  
  I hope this helps.

Take care and have an amazing day!
