Welcome to HP Community

I have gone through your Post and would like to help

You mentioned that the external monitor works fine. If that's the case it's unlikely to be an issue with your Graphics Card. This seems to be an issue with the Notebook display since the external monitor is working

Tried getting to BIOS and check if that works

I suggest you contact HP Support for Service Options
