    updated to Mavs with Tiamo routine and SSD as boot.
    has issues waking from longer sleep, say 30 mins plus.
    The screen wakes up and I see the desktop, but I get the spinning beachball.
    The only thing that works from that point is a 10 sec power button hold to shut down.

    it's the OEM pram batt. Might that be it?

    I also have heard, though not proven, that the OEM 512M RAM may coz the issue in slots A-1 and 2.
    So I removed completely to test. Still have 8G ram installed in the proper manner.

    Could I safely remove the hibernation routine with Terminal?
    pmset hibernatemode 0. or perhaps change it to a longer default, say a couple hours?
    I have Energy Saver/Computer Sleep set to 1hr and that hasn't helped the issue. I just set to 3 hrs to see if there is any change.

    I've tried pram and pmc reset. No change.

    I also ran AHT from the disc, for what it's worth, the long version.
    No issues.

    I wonder if its' a certain app or perhaps java?
    It's on my wifes side of the machine and she uses java. But wouldn't java be a global install?
    In any case, with OEM ram pulled and Computer sleep set to 3 hrs, so far so good.

    nope, OEM ram and 3 hr sleep time didn't make a difference.

    so I changed sleep computer to never and sleep drives whenever possible.
    so far, seems that combination works.
