@johnspc,

 

Thank you for posting on HP Support Forums. It is a great place to find the help you need, from other users, HP experts, and other support personnel. I see from your post that you are having issues with the display on your HP all in one PC. Don't worry we'll work together to help you find a solution.

 

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

Have you checked if the issue persists in the Bios?

Did you try to run a system diagnostics test from F2?

 

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

 

Perform a Hard reset on the notebook

 

Many startup errors and other problems can be resolved by decreasing the amount of power stored in hardware components. Decreasing stored power is sometimes referred to as a "Hard Reset". Use the following steps to perform a hard reset on a computer:

1. If Windows is open, click Start and then Shutdown.

If Windows is not open and the computer has power, press and hold the power button on the computer until the computer shuts off.

2. With the power off, disconnect the power cord from the back of the computer.

3. With the power off and the power cord disconnected, press the power button on the computer for 5 seconds. The power light indicator on or near the power button might turn on briefly but then go out.

4. Reconnect the power cord and turn on the power.

 

Next thing, I would suggest here is to uninstall the display drivers from device manager:

Right-Click on start button> click device manager> expand display adapters>then select the display drivers that are listed and right-click on it and uninstall the drivers.

Check the box that states delete the software for this device.

Now restart the computer and then update the Bios, Chipset and graphics card drivers on your PC from our HP support website, using this link.

 

Also, download and install HP support assistant on your PC. It should automatically download and install the latest updates and drivers for your PC.

Refer this link to know how to use HP support assistant.

 

Alternatively, I would suggest here is to follow the steps suggested in the support document for - HP PCs - Sleep and Hibernate Issues (Windows 10, 😎

 

Please let me know if this resolves the issue, or if you require further assistance!

Eagerly waiting for your response!

that said, If the information I've provided was helpful, 

give us some reinforcement by clicking the solution and kudos buttons, 

that'll help us and others see that we've got the answers!

Good Luck.
