    HELP....Car PC self hibernates!

    Hello all,

    I got a carPC that goes into hibernation on it's own after 5 minutes only in this certain situation:

    -When I have music on PAUSE.

    AND

    -Only after coming out from hibernation. If it's a fresh restart it stays on indefinetly.

    AND

    -Only when Road Runner is running. If I exit out to the Desktop, it also stays on indefinetly.

    System specs:
    Intel D201GLY "Little Valley"
    1GB Ram
    80GB Fujitsu HD
    BU353 GPS
    Lilliput 7" touchscreen

    RR version 12/06/07
    Winamp 5.13
    WinXP Media Center 2005
    Power settings in XP are set to Always ON.

    I can tell it's not a wireing issue cuz it stays on if music is playing or during a fresh restart. Any advice on where to start checking?

    Thanks

    Hmm.. one possibility is that it's going into hibernation when your CPU is drawing alot of current, causing the voltage at the power supply to drop below the threshold, initiating shutdown/hibernation. Can you try doing something very CPU and/or GPU intensive to see if you can cause it to shutdown? Maybe by running a 3d game?

    If that causes hibernation/shutdown, then I would look into:
    1) finding a better ground
    2) upgrading power and ground wires to thicker gauge wires

    That is a good idea, but those little valley ones are like the via systems, really low power. You cant really overload an available DC-DC with one of them unless you try!

    I wouild look at your power settings just to make sure. The whole inactivity for x minutes, does blah, and turn off the monitor in y minutes and all that. I know you say they are ok, but they can get reset sometimes without knowing.

    If those are fine, then do you have a USB keyboard or something with a hibernate key? You could be getting your signals crossed somewhere, and the computer is picking up the signal for the GPS lets say, and interpretting it as if it were a keyboard, and hibernating it. I would find this unlikely, but a possibility, even more so since you say if you are at the desktop nothing happens.

    What RR skin are you using? If you use the default BMV2 skin, does the same thing happen?

    Thanks for the tips guys. I'll try running the default skin to see if anything happens.

    problem solved

    If anyone needs to know what happened for reference.

    Set in rr.ini:
    hibernateaware=false

    Problem solved.

    Guess RR does some funny stuff in the background after a few hibernates. This only happened for my particular motherboard, mentioned above. When I had a old Compaq Presario in the carPC, I did not have this problem.

    Thanks to those who tried to help.
