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

I understand your HP All-in-One - 20-c416il is not powering on, and you suspect a power button issue. Let's go through a few steps to help diagnose and potentially resolve the issue.

Check Power Source and Cable

• Ensure the power cable is securely connected to both the PC and a working wall outlet.
• Try a different wall outlet to rule out power supply issues.
• If available, test with another compatible power adapter.

Perform a Hard Reset

This helps drain residual electrical charge that might be preventing startup:

• Disconnect the power cord from the PC.
• Press and hold the power button for 15 seconds.
• Reconnect the power cord and try turning the PC on again.

Inspect the Power Button

• Press the power button and observe if there's any tactile feedback or if it feels stuck.
• If the button feels jammed or unresponsive, it may be a hardware issue requiring service.

Check for LED or Fan Activity

• When you press the power button, do any lights turn on or fans spin?
  • No lights or sounds: Likely a power supply or motherboard issue.
  • Lights blink or fans spin briefly: Could indicate a startup or hardware fault.

Try a BIOS Recovery (if applicable)

If the PC shows signs of life but doesn’t boot:

• Turn off the PC.
• Press and hold the Windows + B keys, then press and hold the power button for 2-3 seconds.
• Release the power button but continue holding Windows + B until you hear beeps or see the BIOS recovery screen.

I hope this helps. 

Take care and have a good day.
