Laptop display starts turning on & off suddenly & especially while playing games

[alapan17]

My laptop display starts tuning on & off suddenly. It happens more frequently when I starts playing a game.
When the display starts flickering also the keyboard back lights flickers at the same time.
I have also checked the display by connecting to an external display, it also flickers there.
Could this be a hardware issue?

For your reference, I will be attaching a link of the video that demonstrates the problem

Welcome to the HP Forum.

Your PC might be blue screening. The blue screen error code can sometimes help to find the cause.

Enter Advanced System Properties in search. Select the result.

Select Settings in Startup and Recovery which is located in the Advanced tab.

Uncheck automatically restart and click okay. Click okay again.

The PC should blue screen the next time it does a restart.

Get back to the Forum with any blue screen errors you encounter.

Hi,
I have updated the video reference link in the post. Now you can see the issue more clearly. As you will see in the video, my pc does not restart. It just flickers the display.

UPDATE

If I connect my laptop with external keyboard, mouse and external monitor, Sometimes the laptop original screen and the keyboard does not work at all. But when it does not work, I can use may laptop perfectly fine using the external monitor and keyboard. As if when the original screen and keyboard does not work, the display flickering issue also does not happen.
It may sound confusing, but this is what I have seen.

Thanks for the video.

Is your PC in warranty? Your PC specs Here look fairly new.

I would contact HP Support if your PC is in warranty.

The USB keyboard, probably all USB functions are doing this, and display are intermittently losing power (a slow off/on cycle). But the PC is not restarting.

I think you have a power delivery problem.

Maybe the power brick or a MB component up to and including the MB may be causing this.

I have already registered a case with ID - [Personal Information Removed] with HP customer support, but the lack of action from HP's side reflects poorly on HP's commitment to customer satisfaction and efficient service.
Please let me know if there are any ways to escalate this issue to higer management?

Have you tried: backing up data and then doing a HP Cloud Recovery to verify a hardware problem? 

Run the PC using only the factory image for a while to check stability.

Sorry to see you are having a HP Support service problem.

I don't work for HP. I can't escalate your issue.

I'll notify a moderator. Maybe a HP employee can assist.
