Hi,

There is a black thick horizontal line of almost 5 mm on my laptop screen, it just suddenly appeared when I turned on my laptop. I do not know how it came and what is the reason behind it. Please let me know how this can be fixed and how it appeared.

Hey there! @VAISHILPI,

Does the issue persist on the BIOS page?

Were there any physical damages to the laptop or screen?

Have you tried checking with an external monitor does the issue persist?
