    Hi All.
    Excuse my bad English, I'm French...
    I've got a Acer Aspire 7720G.
    After BIOS update, the motherboard doesn't restart. :mad:
    I bought an other motherboard and installed it but it doesn't correctly work.
    When I install all hardwares, the laptop starts (hard disk, DVD...) but the screen stays off.
    I unpluged Graphic card and restart laptop, the screen switch on and stays in white and the laptop starts too.
    My first motherboard was an ICK70 Rev 1A and I installed an ICK70 Rev 2.

    What is the problem ???

    Please Help me, a motherboard cost 250$

    just use the latest ????.FD file from inside the DOS BIOS FLASH for your model

    should be the same as the 5135 though... version 1.43.

    copy that FD file to a FAT formatted THUMB DRIVE... and follow the instructions in the link in the previos post

    unless you have more serious motherboard issues... that recovery method will work.... just format the thumbdrive,, transfer the *.FD file to the thumb drive...

    then follow the instructions in the first post's link....

    Hi.
    I follow the instructions but doesn't work.
    I format thumbdrive to FAT16 and copy .FD file.
    When I press Fn+Esc and Power button, the fan doesn't spin up, but spin up when I release Power button. My thumbdrive never flash (means access).

    i think you have to release the power button... then the fan will stay on for more than 10 to 15 seconds...

    when the fan turns off... remove the USB drive and try to reboot

    no need to be bootable... the thumb drive needs only to have the latest BIOSfile.FD on the thumb drive...

    that is the only file you need on the thumb drive... having other files on the thumb drive will cause failure
