Hi @Julissaxoxo,

Thank you for visiting the HP Forums! A great place where you can find solutions for your issues with help from the community! I came across your post and wanted to assist you. I understand you are having issues booting your HP All in one PC. Don't worry we'll work together to find a solution for you.

To provide you with an accurate solution, I'll need a few more details:

Have you recently made any software or hardware changes on the PC before the issue started?

Did this happen after a power surge or power outage?

In the meantime, let's try these steps here:

Perform a Hard reset on the PC: 

Completely resetting the computer can resolve many issues that cause a blank screen. Follow these steps to perform a hard reset:

1. Turn off the computer.

2. Disconnect all peripheral devices and remove all USB devices and media cards.

3. Disconnect the AC power adapter.

4. Press and hold the power button for at least 15 seconds.

5. Reconnect the AC power adapter.

6. Turn on the computer.

   If the blank screen issue is resolved, you are done.

   If the screen is still blank, continue with the next step to listen for computer beeps and look at the lights.

Attempt a BIOS recovery > All in one

If the above steps work and the display turns on: Perform a hardware test to be on a safer side.

Hello ive tried what you suggested me to do and none of it works even with the links provided. I have not made any software or hardware changes I was playing an online game and when I turned off my computer and tried to turn it back on again it was just a black screen

My pc has been off for a couple days and yesterday I tried turning it on and it turned on again and at night I put it on sleep instead of shut down so I could be able to use it the following day and I have used it today and when I tried putting it back on sleep mode I came back later on and it was a black screen.

It looks like you were interacting with @Jeet_singh, but he is out for the day & I'll be glad to help you out, 

I'm the Riddle_Decipher & I'm at your service. 

If the computer is booting into windows when restarted, did you attempt to update the BIOS?

Did you ensure the hybrid sleep or hibernation is turned off?

Please check with the power options and ensure it's turned off under advanced options, that said, if the computer isn't turning on anymore or has a black screen on display even after a restart, please check with if there are lights on the device and if they are blinking (capture the blink codes), also check if the computer is powered on, if not check with an alternate power cord and another monitor to identify the issue accordingly.

Follow the below steps for more instructions:

Step 1: Enabling the Keyboard in Windows 

Skip this step if the computer does not enter sleep mode or if the computer wakes unexpectedly. 

Follow these steps to enable your keyboard to wake your computer from sleep mode: 

1. In Windows, search for and open the Device Manager. 

2. Click the arrow next to Keyboards and double-click the name of your keyboard. 

3. If the Power Management tab is available, proceed to the next step. 

If the Power Management tab is not available, click the Change Settings button if it appears below the Device status box. The same Keyboard Properties window opens with the Power Management tab available. 

If you are prompted for an Administrator password or confirmation, type the password or provide confirmation. 

1. Click the Power Management tab and make sure that the box next to Allow this device to wake the computer is checked. 

2. Click OK, and then test to make sure that the keyboard can now wake the computer. If the computer still cannot wake from sleep mode, continue using these steps. 

3. For instructions on how to update the BIOS of your computer, see one of the following HP support documents: Updating the BIOS (Notebooks)

My pc still has a blank screen when I try to turn it on so I don't see how the steps provided can help me. The light behind the screen does turn on when I try to turn on my computer and I can hear it turn on it's just a black screen

Thank you for replying with this detailed response 😉 

I appreciate your time and efforts,

It seems like the LCD may have an issue, I recommend you check with an external/alternate monitor connected to your device,

If there's no display on the other monitor (or you don't have another monitor) as well, check if it works on BIOS (by tapping F10 during restart) and then on safemode to reinstall the graphics card drivers, however, If the other monitor works or has a display, it would confirm an LCD failure and I suggest you Contact HP to have it either repaired/replaced:

HP Technical Support can be reached by clicking on the following link: http://h22207.www2.hp.com/us-en/?openCLC=true

(1) Once the support page opens please select the country in which you're located. Next, enter your HP model number on the right.

(2) Next, choose the 'Contact Support' tab at the top and scroll down to the bottom of the 'HP Support- Contact' page to fill out the form provided with your contact information.

(3) Once completed click the 'Show Options' icon on the bottom right.

(4) Lastly, scroll down to the bottom of the page and select 'Get the phone number.' A case number and phone number will now populate for you.

They will be happy to assist you immediately. 

If the unit is under warranty repair services under the manufacturer's warranty will be free of charge.

If I have helped you resolve the issue,
