    Hi everyone,
    two days ago I made the huge mistake of "upgrading" the BIOS of my M14xR2 from A04 to A08.
    Since then, I got numerous hard shutdown ( can't power on without being on AC ) while gaming on battery, which never happened before.
    I also got my very first BSOD since I got the machine.

    I read somewhere that it is possible to go back from A08 to A04 using a methode called "Blind flashing" or something like that; involving extracting the firmware onto a USB Key and booting with a certain key pressed. However, I can't seem to find a proper step by step tutorial on how to do this.

    I would appreciate it if someone could explain the procedure to me !

    How about trying bios A09 first?
    I don't see why you'd need to blind flash, you do that when the GPU no longer outputs video.

    I'd really want to avoid A09 as I've read numerous times that people had to get their motherboards replaced after flashing this BIOS. The nVidia card was not detected anymore for them.

    I would need to blind flash because the regular tool performs a security check that prevents me from flashing back to A04 ( something to do with new Windows 8 features on the A08 and A09 BIOS ).

    This would be a good way to go.
