My All-in-One PC does not open. Whenever i plug it the port smells burnt, where is the damage? Is the PC broken or the charger? No power comes through the PC. Thank you

Hi @dree4,

Welcome to the HP Support Community.
 

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

If your HP All-in-One PC emits a burnt smell when plugged in, and no power reaches the system, this is a serious hardware issue. Here's how to assess the situation:

Possible Causes

1. Burnt Power Adapter (Charger)
   • If the burnt smell is coming from the adapter or plug, the charger may have shorted or failed.
   • Try using a different compatible HP charger (if available) to test.
      
2. Damaged Power Port or Motherboard
   • If the smell is from the PC itself, especially near the power port, it could indicate:
     • A burnt power input circuit
     • A shorted motherboard component
     • Internal power surge damage
        
3. No Power at All
   • If the PC shows no lights, no fan movement, and no display, it’s likely a hardware-level failure.

What You Should Do Next:

• Do not plug it in again until it’s inspected—continuing to use it could cause further damage or pose a fire risk.
• Check the charger separately:
  • Smell the adapter and cable ends.
  • Look for melted plastic or discoloration.

I hope this helps.

Take care and have a good day.
