    What makes you have to shut down??

    I am going to build a custom box, and run my old desktop hp in it in my car. It is an amd 1ghz processor board. My question is, why is it that you have to shut a computer down??

    I want to be able to get in my car, turn on the key, and have the computer come on. But when i leave the car, i do not want to have to shut it down, and wait. I want to be able to just turn off my key and get out of the car.

    I have read that with the mini-itx computers you can do this.----is it possible to do on mine, or what shoud i try??

    P.s. I will be running an inverter most likely.---thanks in advance for all of the replies-----

    I kinda thought this would have been obvious, but if you dont shut your machine down, its gonna drain your battery.

    The key word is hibernate.
    Search for it here and you'll get your answer.
    Have you looked in the FAQ yet?
    How about the Wiki?

    Also, if you use an opus power supply or get a shutdown controller you won't have to physically shut it down by pressing a button, it will send an atx pulse for you when you turn off the car and shut down (or hibernate) by itself.

    Thanks for the rudeness--- i meant shut it down as in using the start menu to shut it down.----if you would have read the whole post, you would have seen i did not mean turining off the power.


    thanks to all of you so far with real replies

    The simple answer is that you will need a shutdown controller (SDC) to do this - the shutdown controller would detect voltage on your ACC line. If that line does not have voltage, it will initiate a shutdown procedure to the PC (i.e. it sends a pulse to the motherboard power switch pins thus "faking" you pressing the off button).

    When the SDC detects voltage on the ACC line, it will wait a few seconds for voltage to normalize and send a pulse to the PC to start up.

    Next time search. It is one of the core abilities of a complete carpc and has been discussed here MANY times.

    sorry for not searching first. i just did not know what to search for for sure. The other part of my question really was that why do you actually have to shut down a computer instead of just hitting the off button.(even in a house) I was jsut not sure what the shutdown feature is actually doing.


    Thanks again guys for all of the replies

    Shutting down to us means shutting off power to the computer. If you don't shut off power, your car battery will die. To aid in start up times, most of us here use a windows feature called hibernation which typically boots windows a lot faster than a cold boot. Get acquainted with the hibernation technology in Windows XP. Google it or search here for further explanations.
