  • Lockup when hitting bumps

    My carputer has been locking up every so often and I have finnaly found the cause. If I go over any decent size bump (say railroad tracks), everything locks.

    I attribute this to read errors and things, but is there a way to make i/o errors not kill the os?

    Post some pics of how your CarPC is mounted and how the components inside the CarPC are mounted.
    I'd say there's a 90% chance there's something loose and only 10% chance that your HD is failing/skipping.

      i'll take some pics tomorrow, but I have the basic ampie case plus via m10000. The drive is a 2.5 mounted on the little foam mounts they give you. I'm pretty sure nothing is loose, and the drive is brand spanking new.

      My case is under the front passenger seat and it's not actually attached to anything, just sitting on the floor. I'll have to take the seat out to mount it to something.

        Mine's running off an inverter and sometimes a bump will jar the A/C power cord loose just enough to freeze or restart the computer. I know the problem, just haven't had a chance to redesign the system. Yours might be a similar problem.

          I have a dc/dc power setup and the wires are all connected via locking molex. My power to my lcd is via a normal psu molex to a ****ty radio shack molex clone. I've been meaning to make that a better setup... but I don't think it's loose though, hmm.

            I have an M1-ATX and I was havign a problem with the cheap 4 pin power molex plugs they used. My 3.5" drive was losing power and locking up because they were making poor contact. I squeezed the round connectors a bit with some needle nose pliers and everything has been fine since.

              Mounting the actual case to the car will seriously reduce the amount of shock. Id do that even if you find a different cause to the problem.
              I had my case mounted to the rear parcel shelf (underneath in the boot) and I only had it mounted from the front of the case, so the back would sag down a bit and jolt when going over bumps. This would cause playback to skip for a second or two (using a 3.5" drive). I have since mounted it more sturdily and no more skips

                  The power molex off the ide cable was quite loose. I soldered on a different one and it seems to have fixed the problem. Once I finish my carputer setup (ie: finish the lcd bezel and get my usb extension cables in the mail) I'll see about taking the seat out and mounting the little guy to the body.
