@Sanket_7, Welcome to the HP Support Community!

What model HP Notebook are you using?

Connect an External monitor and check if you still have these Black lines.

Go to the BIOS screen and check if the lines persist.

1. Shutdown the computer using the power button.
2. Power the computer back on.
3. As soon as you press the power-on button, immediately begin Tapping the F10 button to access the BIOS screen. Check for the Black lines.

Let me know how this goes.
