    Hi,
    I got my mid 2010 imac for about a month...
    I always leave it on, and set it to sleep when I am not using. Yesterday I went to bed and made it sleep. Today when I woke up, it was off. I checked if any power break happened, but it didnt. I checked the log, and there just says the hour when I set it to sleep yesterday, and than it starts the todays log. I am very preoccupied that I have a hardware problem.
    What could happened with it ?

    EDIT
    I just Found this at the todays log, about the time I started the imac:

    16/10/10 12:28:17 configd[13] Sleep: Platform Failure - AC
    com.apple.message.domain: com.apple.powermanagement.sleep
    com.apple.message.signature: Platform Failure
    com.apple.message.result: Failure
    com.apple.message.uuid: 1C6DA3F6-F7B0-4DF0-9E2F-3E96D9B88E06

    what does that mean ?

    It sounds to me like your iMac got hit by a power surge, and damaged the power supply. Did you have it plugged into a surge protector or a UPS?

    Yes I do.
    Its acting normal now, but I'm afraid it will happen again.

    I also found out this line in the log

    16/10/10 12:28:03 DirectoryService[15] Improper shutdown detected
    16/10/10 12:28:04 kernel systemShutdown false
    16/10/10 12:28:18 kernel Previous Shutdown Cause: -128

    Does anyone knows what this means ?

    could it have been unplugged accidentally? if it happens again, I suggest you have it checked with your reseller/ Apple store.

    If you do it now, before it happens again, it will reset the SMC and hopefully prevent a re-occurrence from happening. If it does happen again after resetting the SMC then a trip to the Apple Store or an AASP would probably be called for.
