My desktop won't turn on

[Shelbycobra14]

I can't turn my computer on. I changed outlets and still not working. Light isn't on to indicate it's willing to turn on

@Shelbycobra14, Welcome to HP Support Community,

Thank you for posting your query; I’m here to help by guiding you through steps to resolve this issue

1. Check the Power Cable and Connections:

• Ensure that the power cable is securely connected to both the power supply and the computer.
• Check for any visible damage to the power cable, like fraying or cuts. If you see any damage, try using a different power cable (if you have one).
• If the power supply has a power switch, make sure it's turned on.

2. Try a Different Power Outlet:

• Even though you’ve tried a different outlet, it might help to test in a known, working outlet like one that powers other devices.
• If you’re using a power strip or surge protector, try plugging the computer directly into the wall to rule out a faulty power strip.

3. Inspect the Power Button:

• Make sure you're pressing the power button correctly and that there’s no debris or blockage around it. Try pressing and holding the power button for at least 10 seconds.

4. Check for LED Lights or Sounds:

• Some HP All-in-One PCs have a small LED light near the power button or elsewhere on the system. Look for any faint lights that might indicate power.
• Listen for any sounds (like a fan starting or hard drive spinning) that could show the computer is trying to power up but not display anything on screen.

5. Perform a Hard Reset:

• Unplug the power cord from the wall and remove any attached peripherals (USB drives, external speakers, etc.).
• Press and hold the power button for 30 seconds to discharge any residual power.
• Plug the power cord back into the computer and try turning it on again.

6. Check the Power Supply:

• If the computer still doesn't turn on, the power supply might be the issue. HP desktops often use external power adapters (in the form of bricks). Ensure the power supply unit is not damaged.
• If you're unsure whether the power supply is working, you can test it with a multimeter or check with a known working power supply of the same type (if available).

7. Check for Faulty Hardware (if possible):

• If you are comfortable opening the back panel (and your warranty allows), check for any loose or disconnected cables inside, especially the connection between the motherboard and power supply.
• Look for signs of overheating or physical damage, such as burn marks or unusual smells.

8. Test with External Monitor (if screen issue is suspected):

• It's worth confirming that the issue is not with the display. If you have an external monitor available, try connecting it to the computer. If the external monitor works, the issue may be with the screen itself.

9. Check for Any Error Codes or Lights:

• Some HP computers have diagnostic LEDs or display error codes to indicate problems. Check for any blinking lights or unusual patterns that could point to a specific issue (consult the manual for your model if necessary).
