    Hello, I was wondering if anyone could help me out...

    I've got a Pismo 400 that had been working great. It has 2x 256 meg DIMMS installed for a total of 512. I took the thing apart to put a new HD in. The hard disk works fine, but what I discovered was that it would not boot up if a DIMM was installed on the "bottom" RAM slot.

    I tried using several different RAM chips, it will boot with RAM in just the top slot, but will not if RAM is installed in the underside of the processor card. The only thing that happens is the hard drive spins, but the screen and everything else stay powered down. I was very careful, and there doesn't look to be any damage... does anyone know why this would be happening? Suggestions for fixing the problem?

    Thanks, Adam

    Hi amc,
    The only thought about the RAM install in that second slot is that with the 500 and (I believe 400 as well) make sure the RAM slot is snapped down securely. I've seen several posts where people (myself included) had to press pretty hard down until it snapped in to place and was properly seated.

    If you're sure it's been properly seated, I'd take a look at the RAM chip; it also could be the new HD and OS...sorry, didn't check to see what OS you're running, don't like the RAM. I have 1Gb of RAM installed in my pismo500 from Crucial and have no problems with it. Good luck.
