HI. I tried rolling back and also downgrading my current HP bios which is the one that fixes the spectre issue. It seems to be slowing the computer a little bit and making it run warmer. After trying all the usual ways of rolling back and downgrading, and having no success, I learned that HP locks many of their bios's making them unable to be rolled back or downgraded (you can reinstall the current bios only) especially if they have an important security fix. Is it possible to remove this "lock" or whatever it is so that the current bios can be downgraded and an older bios can be installed? Thanks.
