    Hi

    My Macbook 13" Mid 2010 (8,1) was showing a picture dia show. Then the Battery Power was low and it going into the sleep mode.

    The next day, i plug into the power adapter and want to boot up the macbook. But it beeps the SOS Code 9 Beeps - 3 short, 3 long, 3 short beeps.

    I try to
    - Change the memory modules -> same error
    - Remove the memory modules -> long beep, long beep
    - Create a firmware restore CD and press and holt the power button
    The Restore CD is not the right one, i know, but i cannot find the cd for 8,1 Macbooks. So try it, but no success. It start to read the disc, SOS code, then it put out the CD.
    - SMC PVR Reset -> all keyboard possibilitys i try. -> same error
    - Remove the Battery and work with power Adapter -> same error
    - Create an OSX Lion Recovery USB Stick -> same error
    - Remove the Harddisk -> same error

    So.. i cannot believe, that only why the power was gone, the mainboard is broken/defect. I think the SMC should be reprogrammed.. but how?

    The Firmware-Updates are pkd files, which i decompress and burn the files on a CD-Rom. Also no luck.

    I think it must exist an possibility to burn the SMC Flash. Like the old recovery-CD's. Why they d'ont have it for the newer MAC's?

    I also check if exist an battery on the logic board. But i cannot find it.. so it must be one of the little pieces on the board, whitout an possibility to remove it.

    On Youtube and Google they are a few others, they have the same Problem. But the have no other solution then to change the mainboard /logic board.

    Thanks.

    What does "Change" mean... Brand new memory modules or you just swapped existing memory to different sockets?
