    Run ipconfig /all from cmd and note down the MAC address of the LAN card.

    I have personally tested this unofficial bios update but try at your own risk; just execute the exe and wait. It'll be seemed that your PC is hanged but don't touch it. After flashing it'll be rebooted automatically.

    The problem of not accessing BIOS or boot menu will be solved eventually.

    Not wireless, the ethernet one (should be Realtek chip). It will be erased while flashing.

    In my tests, no problem is found.

    Its your choice.

    Hi, I have the same laptop.
    I previously set a password in my bios but cannot recall it. Would flashing the bios reset the password?


    Thanks for the bios. Flashing it got rid of the password. I was able to enable VT.
