My HP Pavilion 23 All in One wont power on

[Arobe44]

I have had my HP Pavilion 23 touch screeen all in one for about 7 months and when I went to turn it on the other day it wouldnt come on. No fans, no lights, no nothing. All that happens in the led light above the power button flashes once and then stops. I am a college student so I desperately need my PC. Help! I have unplugged and plugged back in, plugged into wall instead of surge protector, tried a hard reset and still nothing.

Hi @Arobe44,

Welcome to the HP Support Forums 🙂

I would like to take a moment and thank you for using this forum, it is a great place to find answers. For you to have the best experience on the HP forum, you could also visit our HP Forums Guide for First Time Here? Learn How to Post and More.

As I understand the computer is not turning on or is displaying only a black screen and the battery isn't charging either,

Don't worry as I have a few steps which should help to resolve the issue:

If the computer does not start, the LED lights do not glow, and the display is black, you can perform one or more of the following actions to resolve the no power issue:

(Click on the blue letters to get more details about each step)

1. Examine the adapter and power cord for physical damage

2. Test the power from the AC wall outlet to the notebook connector

3. Start computer using the battery only

4. Check that the lid switch moves freely

5. When you have completed the troubleshooting steps, there should be power available to the computer. When you press the power button, the LEDs should glow, and you should hear the sounds of the fan and the hard drive spinning.

* If the battery does not accept the charge or the notebook does not turn on without the AC adapter, contact HP to order a replacement battery.

* If the LEDs do not glow, and there are no other indicators of power being available to the computer, contact HP for technical assistance in troubleshooting a potential problem with the AC power connection or the system board.

* If the LEDs blink or the computer beeps, but it does not start, go to HP Notebook PCs - Troubleshooting LED Blink Codes or Beep Codes During Startup or Boot.

* If the LEDs glow but the computer does not start on either battery or AC power, go to Troubleshooting Black Screen Displays with No Error Messages During Startup or Boot.

Eager to help,

I hope you have a good day ahead,

And Feel free to ask your queries as this forum has some of the best people in the world available and ready to help.

This is an all in one desktop not a laptop so the above doesn't apply as there is no battery to run it off of
