horizontal green line appearing on the screen of my laptop

[ademasin]

yesterday, a fix  horizontal green light has sudenly appeared on the screen of my HP notebook.

I have tried to restart my computer, but it is still there.

And when i do a print screen, it does not appear on the image. 

My notebook is relatively new, i bought it a few months ago, and it did not receive any shock to my knowledge.

Any idea on how to check what this is and what to do about it ?

MAny thanks

@ademasin,

Welcome to the HP Forums!

Thank you for posting your query on this forum, it's a great place to find answers.

Don’t worry, I assure you I will try my best to get this sorted.

I recommend you boot the computer to BIOS by tapping the F10 key on startup and then check whether you see the green line in BIOS.

If the line doesn’t appear in the BIOS, then I recommend you update the BIOS and the graphics driver from the below link and check whether the issue is resolved.

If the line appears in BIOS then, I am sending you a private message suggesting the next course of action.

Let me know how it goes and you have a great day!
