I used a hex editor to compare the bios yours gave me and the ones i already have and it seems to have alot of 0xFF hex values in place of alot of regions where there was data before. https://support.hp.com/us-en/drivers/sel...2-1?sku=8VP56AV heres the link for my exact bios version i was comparing against just in case u might have accidently found the wrong envy x360 with a 4500u since theres more than a few versions.
