Hey guys, I bought a second hand Acer laptop off craigslist and it has a supervisor key set in the bios and i have had no luck removing it. Ive tried everything I can think of, Including removing the cmos battery and attempting to flash the bios. It wont let me flash the bios due to the bios version being the same, and i had the cmos battery removed and the laptop battery unhooked for at least 45 min when i tried that. I also tried the bios password bypass with https://bios-pw.org/ and that only allowed basic access. Any suggestions? would really love to be able to get into the UEFI bios on this thing.
