My HP Pavilion Laptop 15-cs3xxx laptop screen intermittently goes black

[billfee]

I am using the HP trouble shooting tools in HP Support Assistant.

Everything looks good.

How can I trouble shoot this problem?

Haas this happened to other people.

Are there any HP troubleshooting tools I can run to check what is wrong?

Hello @billfee 

(1) Double check with external monitor connected via vga/hdmi cable. Can you see the boot screen/Windows on the external monitor?

- Shutdown notebook

- Power off external monitor

- Connect vga/hdmi cable

- Power on external monitor

- Power on notebook

(2) Please report your results

I am not using an external monitor.

It is my laptop display that is having the problem.

Hello @billfee 

The external monitor test will show if GPU or internal screen is affected.

Kind regards

I have got exactly the same problem. The screen goes black or staerrts flashing. I do not believe it is a hardware problem. If I start up with BIOS settings, I have not got this problem. When I return to Windows from the BIOS settings menu the problem has dissapeared.

For me it seems to be a Windows 11 or a driver problem. Did anyone else investigate any further?

I reset my PC to Windows 11 version 22621.674 and the problem went away!
