    Out of nowhere, i have to manually put my macbook to sleep and wake up up when i open and close the lid. I'm running Mountain Lion with all updates. I think this problem might have started after i upgraded the ram to 8GB, but i don't see how that can effect it. Any ideas?

    Took a look at those links and couldn't find a solution. Is this more likely a hardware problem or a software problem? It's really annoying.

    It's more likely software. There's likely a process that's running that's preventing it from sleep. You just have to find it. There have been many threads on sleep issues. You may find a solution by searching the forum and reading some of those threads.

    So you don't think this could have been caused by a ram upgrade?

    Not very likely. Software is a much more common culprit.

    Caffeine won't keep a Mac awake with the lid closed.

    I'm having the same problem and resetting the SMC does fix it but the problem comes back again...trying to determine why.

    Does it only happen when the laptop is plugged into AC?


    I had that problem. Turns out I had a pending document in the print queue. Your macbook won't go to sleep (on AC power) if there's a document waiting to print.


    Go figure.

    It tries to be TOO helpful. It figures since it's on AC, it's OK for it to wait for the printer.

    If OSX were perfecTER, it would let us configure a sleep-anyway timer. ;)

    Same thing happened with me - a pending print job for a printer that was no longer connected to my MBP.

    It is most likely a software issue, but if you recently upgraded your RAM and the sleep issues started happening just after that, I'd suspect your RAM. Put the old RAM back in and see if you still have issues.

    OSX is so optimistic, it will literally wait until the end of time to print your document. Even if your printer was destroyed in a flood.
