Hi @Beer3,

Welcome to the HP Support Community. 

I'd like to help!

Let's try these steps below:

1. Turn off your computer 

2. Make sure you have connected the power cable 

3. Turn on your notebook, as it is starting press the F10 button repeatedly Once you are in the BIOS, if the lines are still present, it is likely a hardware failure.

Hope this helps! Keep me posted for further assistance.
