  • Anyone else having any issues with Cold weather?

    It seems that my carputer, doesn't want to come on in the mornings, when it has been around 20 degrees Farenheit. I go to boot it up and it will begin to boot, but I never get any video. I then usually will let it run a few minutes, then I reboot it and the video will work fine.

    I am using an ATI (Built by ATI) Radeon 9200 Video card wtih 128mb Memory on the board. I have not yet had the time to figure out where the problem actually is. Just wondering if anyone else has run into any problems with the cold weather. I know we aren't that cold here compared to people in the northern US.

    Thanks,

    The problem is your lcd. The liquid crystals can freeze and won't be able to display anything. After awhile when things warm up a bit, everything will be fine.

    The first couple days that temps here in Philly were below 20 F, my computer booted but I would get no video. Funny thing though - I think eventually that the lcd gets used to the cold, because this morning when I started the car, it was 1 degree F and the display was working, although reluctantly as it was very dim for a few minutes.

      I have noticed it being Dim at first. It does show No VGA Signal, when it first comes on.

      Would this be the same issue you are mentioning with the Crystals?

        It sounds like your hard-drive is getting too cold to start moving.

        Does your drive have fluid dynamic bearings?

          Here is the Model: http://www.seagate.com/cda/products/...81,579,00.html

          Here is the Spec Sheet on it: http://www.seagate.com/support/disc/...t3120022a.html

          Didn't think about that, but the Seagate is Fluid Filled, not sure what type of fluid but it does state that.

            Check out that PDF for the Seagate you listed above...

            Operating Temperature -> 32 to 140 F
            Non-operating Temp -> -40 to 158 F

                  HDs do not freeze, the bearing lubricant's viscocity increases with lower temps. This causes the drive to spin slower. If the RPM is low enough the drive will not detect.

                  Freezing is the point at which a liquid becomes a solid. This is not happening to your drive. LCDs are also subject to 'slowing' until they warm up.

                    Well yes I know that, but instead of that 6 sentance description of it I figured "freezing" was good enough.

                      Well that's odd... I have a Seagate 80GB which (I'm pretty sure) has Fluid bearings and my comp has booted fine in temps as cold as -10F!

                      I'm not absolutely certain mine has FDB because I don't want to run outside to check the model number. However, I checked their website and they only have one 80GB SATA HDD listed, so it's a pretty good bet.

                      My aux fan screams like a newborn in that temp, so I don't run the comp long when it's that cold, but it has booted 2 or 3 times below 0. It's never failed to boot....

                        It's why I asked him whether the hdd had fluid dynamic bearings!

                            If he isn't even seeing POST then it isn't his hard drive. Plus I doubt 20 degrees is low enough to cause it not to function. I have never had temps below 0 but plenty below 20 degrees and never had a problem with my seagate drive.

                              but the thing is that it is booting. so it can possibly the hard drive not spinning up to speed.

                              as far as the video, i am begining to wounder if the heatsink design on your unit is causing initial condensation causing a short which is forcing the video output system to shut down for boot or its something with the display unit.
