    Subaru Newbie - Alternative way to shut Car PC down

    --------------------------------------------------------------------------------

    Hi everyone, I've just built a car PC and everything seems to be working so far. These are the products I have used:

    Gigabyte GA-D525 Mini ITX motherboard with Intel Atom dual core 1.8ghz
    * 4GB ram Kingston
    * 500GB Seagate 2.5" HDD
    * M2 power supply Mini-ITX M2 Car PC DC-DC 160W 8V-28V ATX Power PSU 12V
    * Micro ATX PC Car Chassis case
    * Lilliput 7" 669 GL-70NP/C/T-H HDMI ultra bright 450cd/㎡ touch screen

    * Globalsat BU-353 USB GPS Receiver SIRF III
    *
    * 4 port USB hub (powered)
    * Tactrix 2.0 cable

    Software:

    * Windows 7
    * Centrafuse 3.6

    However, I am looking for a way to turn the PC off as soon as I turn the motor off (without having to manually put it into sleep mode while the car is running). I've purchased an MpegBox uSDC20D micro shutdown controller but I don't know if it is going to solve my problem. Does anyone have any suggestions as to how I can do this? Also how much power does the PC draw when it sleeps

    Cheers George.............. NEWBIE

    why don't you use the m2 shutdown controller, and configure windows to enter sleep mode on the power button press?

        may not have been the best project to tackle then.
        nah man i'm kidding. luckily you're at a great forum with alot of helpful people.


        your m2 can handle the startup and shut down process without the need of anything else. and i don't recommend setting the system to sleep unless you have a really good battery or a dual battery setup. i know most laptops are only supposed to use <= 1.7watts. i have no numbers or anything, but i'd say carpc's would be right around that as well. some batteries just can't handle that draw after a couple days - which is why the PSU's have a hard off after X seconds setting

        this link will tell you how much your system is drawing:

          Thanks guys, I will look at that. I think that my installer has used the J1 wire lead and hooked it up to the cigarette plug for a power source. This might be my problem.

              WHOA. if he did, you def need to redo it. it needs a dedicated power wire coming from the battery.

                  hold on-- don't just go plugging/unplugging wires without knowing what they are supposed to do.

                  J1: this gets connected via a fused wire, directly to the battery, and should always have +12v on it.
                  J3: this gets connected to a wire that only has +12v when the ignition is turned to 'on' or 'run'
                  J4: this gets connected to a good chassis ground-- usually bolted to the car body.

                  if any of these aren't setup this way, take it back to get corrected.

                  also,
                  J8: this little 2 wire jumper is connected to the 'power button' connections on the motherboard.

                  J10: the jumpers you install here define how long the pc takes to shutdown when you exit the car.

                      it's really hard to know without seeing the car in person. in most cases, no you won't. but murphies law says otherwise..

                            Hi guys, I have just spent all afternoon rewiring the car PC. I have placed an 8 gauge positive wire directly to the car battery with an inline fuse. I then put a new 8 gauge positive wire to the body of the car. I also have run a new wire into the fuse box to obtain accessory power. I opted for option one for the power output connectors on the M2 ATX power supply and I have also run an additional on/off button from the PC into the side console. If I don't put my computer into hibernation mode (with the power settings) when I turn the car off, it shuts off normally but when I start the car, it doesn't resume from where I turned it off. Instead, the computer reboots like its power has been interrupted. However, if I do press the on/off switch and put it into hibernation mode before turning the car off, everything works as it should. Is this normal?Sorry for silly questions
                            Cheers George

                              i assume you mean you connected a 8 ga negative wire to the car chassis-- otherwise, it would be a dead short



                              mode 1 might not be enough for the pc to save the hibernate file--after 45sec, the psu turns off completely, reguardless of what the pc is doing.. a easy way to test this would be to try mode 2, or 3, and see if the psu will correctly trigger, and maintain the hibernate.
