Hi @Vijay0074,

Welcome to HP Support Community.

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

If your HP All-in-One Desktop PC has completely switched off and won't power back on, here are some troubleshooting steps you can try.

Check Power Supply:

• Ensure the power cable is securely connected to both the PC and the wall outlet.
• Try plugging the PC into a different outlet or using a different power cord if available.

Perform a Hard Reset:

• Disconnect the power cable from the desktop.
• Press and hold the power button for 15-20 seconds to discharge any residual power.
• Reconnect the power cable and try turning on the desktop again.

Check for Power Indicator Lights:

• Look for any lights on the power button, back of the PC, or inside near the power supply to see if it's receiving power.

Test with Minimal Setup:

• Disconnect all peripherals (printers, USB devices, external hard drives, etc.) and try to power on the PC.
• If you have access to another power adapter (if it's removable), you can try using that as well.

Inspect for Damage or Overheating:

• Check for any physical damage to the power supply or the PC.
• Ensure the vents are not blocked, and the PC has not overheated (overheating can cause an automatic shutdown).

Try BIOS Recovery:

• If your PC shows no signs of life but the power indicator flashes, it could be a BIOS issue. 

I hope this helps.

Take care and have a good day.
