Updating bios with a thumbdrive
They are smaller, faster, have thousands of times more capacity, and are more durable and reliable because they have no moving parts.Additionally, they are immune to electromagnetic interference (unlike floppy disks), and are unharmed by surface scratches (unlike CDs). I forgot the BIOS password on my HP Probook 6560b laptop. I took this as a challenge though: “Oh goody, I get to kill my BIOS password! Sometimes the best hack is manufacturer support, lol.” So I booted into UBCD and tried my favorite BIOS password murdering tools like cmospwd. Every time I would reboot out of the tool it would error out at a BIOS checksum error and not let me get into the BIOS. Apparently the TPM chip stores the password and can restore it to the CMOS if it sees that it is gone. The first time I contacted HP they said I needed to drive 2 hours to an authorized vendor who I could pay to flash the TPM. So I waited about 4 months and then contacted them again. This time the chat support rep had someone from “HP Complex Problem Resolution & Quality” email me some cool instructions.
Hold the Rog connect button down for 5 seconds and an amber light near the BIOS chips will flash for several seconds and when flashing has stopped the BIOS has been successfully updated..Read the comments on this post for more information. Save to the root of a USB thumb drive “(or save the file to the root of drive D: HP_TOOLS)” -- I used a USB drive, btw... This should bring you into the BIOS where you need to choose “Reset BIOS security to factory default” and confirm by choosing yes (duh) 7. When the laptop reboots, you will see the coveted prompt to clear the TPM, which is shown below.
