    After reading many many things about bios changes when change mxm i couldnt find the solution.
    i have Acer 7720g which had nvidia 9500m gs(mxm 2) and it became faulty so i decided to change to the cheaper nvidia 9300m gs (mxm 1).
    Now, the card looks to work cuz when i open the pc the screen after a bit becomes black and everything looks works "normally" but i dont see anything even with external dvi or vga screen.
    I found a blackscreen bios but i cannot install by Fn+Esc method. i rename the file icl50_1.45_black_edition_40.fd to ICL50HW.fd and leave the other bios files(i can install normally the default bios). Is anything else i can do?

    Thanks in advance
