Unfortunately HP BIOS incompatibility with Windows can only be resolved by fixing the BIOS... unless MS decides to spend the time to sit down and fix HP's error by tweaking Windows. I can see that happening...
I read the instructional (official or semi-official) post in this forum that factory reset leads to BIOS restore as well. It doesn't. So save yourself an effort...
My laptop was fully functional before F.19 BIOS. Not anymore.
@REO51ST your attempts to make it worse will be ignored.
My role is to flag, report to HP and describe the problem, what I have done in abundance (other threads).
Try to make yourself useful. And if you don't have to, like you indicate... don't waste your time where you cannot contribute.
