Power Issue With Hp Pavilion Desktop 580-139

[Nibbles96]

My nephew has an HP Pavilion Power Desktop 580-139, product #2HJ 54AA #ABL which is 6 years old. Yesterday, he powered it on and it ran as usual for roughly 20 minutes, then it shut itself off. He powered it back on but after only 5 seconds it again shut down. Now it will not power on at all. He unplugged it from his surge protector then plugged it directly into the wall receptor but still nothing. He checked the power cable, making sure that is was still tight and also turned the power button off then on but still nothing. He said the fans were running as per usual so I don't suspect that the motherboard was overheating. Iv"e never had this issue myself but figure it has something to do with an internal power connection or module? Any and all solutions to this issue would be greatly appreciated. Thanks.

Hi @Nibbles96,

Welcome to the HP Support Community. 

I'd be happy to help you! 

I understand that you are facing issues with your PC not powering on.

This could be a hardware issue or a power supply.

To troubleshoot your HP Pavilion Power Desktop 580-139 that is not powering on, follow these steps:

Check Power Supply:

• Ensure the power cable is securely plugged into the wall outlet and the back of the computer.
• Test the power outlet by plugging in another device to confirm it’s working.
• If you have a spare power cable, try using it to rule out a faulty cable.

Inspect the Power Button:

• Press the power button firmly.
• Look for any lights or listen for any sounds (fans spinning, beeps) when attempting to power on.

Check for Loose Connections:

• Open the computer case (if you're comfortable doing so) and check all internal power connections. Ensure that all cables are firmly connected to the motherboard and other components.

Power Supply Unit (PSU) Test:

• If you have access to another PSU, try connecting it to your desktop to see if the original PSU is faulty.

Perform a Hard Reset:

• Unplug the power cord from the desktop.
• Press and hold the power button for about 15 seconds to discharge any residual power.
• Reconnect the power cord and try powering on the computer again.

Check for Power Supply Voltage Switch:

• If your PSU has a voltage switch (110V/220V), ensure it is set to the correct voltage for your region.

Remove External Devices:

• Disconnect all external devices (USB drives, printers, external hard drives) except the keyboard, mouse, and monitor.
• Try powering on the desktop again.

Reseat RAM and Other Components:

• Reseat the RAM modules and other components (such as the graphics card) to ensure they are properly seated in their slots.

Check for Diagnostic LEDs or Beeps:

• Some motherboards have diagnostic LEDs or beep codes that indicate specific issues. Refer to your motherboard's manual to interpret these codes if they are present.

If none of the above steps work, there might be a more serious hardware issue. Contact HP Support for further assistance.

Hope this helps! Keep me posted for further assistance.
