    first boot press f10 apply factory defaults and restart, 2nd boot reset security settings to defaults and exit.
    use BCU. you can permanently disable Absolute lock in BCU.

      Hi. First boot f10 and I'm able to reset to factory defaults. on second boot I'm unable to enter bios. It always freeze on entering setup and restart after few seconds. Bios is still locked.

                  What I did:
                  1)desoldered bios chip
                  2)flashed bios with verification
                  3)put laptop together(connecting everything)
                  4) after connecting bios battery and main battery laptop turned on with f5 and f8 light up and fanspin, then it powered off, then again f5 and f8 light.
                  5) on second reboot backlight turned on and Im able to enter bios, in main tab I selected reset to manufactures default and exit
                  6) laptop turned on with f5 and f8 lights, after 1-2min turned off
                  7) removed motherboard and desoldered bios chip
                  8) flashed my original dump and soldered it back
                  9) assembled laptop and again after pluging main battery it turned on with f5 and f8 lights
                  10) after 2 reboots again screen backlight turned on and i was able to enter bios(f10) and its still locked

                  I have assumption that f5 and f8 it is some sort of memory training because its an ddr5.
