    Hi there,

    1Gb of my Macbook air 13" (late 2010, core 2, 1.86ghz, 2gb ram) disappeared. Bank 1/DIMM0 is 1Gb DDR3 1066 Mhz and Bank 1/DIMM0 was empty.
    Can anyone please advise me what to do. Thanks

    Run the hardware test and see what's reported. But in all fairness your looking at a new logic board

    AHT gave me this error: 4sns/1/c00000008: TN0D - - 124. Googled and someone said it's related to high temperature, is it correct?

    Not sure it can help, but maybe reseting the PRAM/SMC would solve. Once I saw a MacBook Pro i7 with just one core working and reseting that fixed the problem.

    Although less likely, onboard RAM can fail. Chances are the only way you'll be able to fix this is with a logic board replacement, although 1 GB does meet the minimum requirement for Mac OS X Snow Leopard.
