    Are there any concerns with laptops and cranking your car?

    If the laptop has a battery installed, cranking should not be an issue (it would be like pulling the plug for a second then plugging it back in).

    As for wiring, it's pretty simple. Here's what you'll have to hook up for MOST shutdown controllers (read the instructions for your SDC carefully first!):

    -constant power IN, should be directly from the battery
    -switched power IN, eg. the ACC line, this tells the controller when to send the on/off pulses to the power button
    -ground
    -power OUT, this will be going to your inverter so that your laptop can be charged by the inverter
    -(may or may not be) ground "OUT" for the inverter, you may also just ground the inverter to the chassis (remember to use a single ground point for everything)
    -2 pins for your ATX switch, these go to the power button that you've soldered on to, polarity should not matter so either pin goes to either pad on the button

    Hope that makes sense and helps you a bit.

    Ok, so what if my battery cannot hold a charge anylonger, and I can't buy a new one right now?

    It may not be an issue if you are using an inverter. If it is, you could use our tank circuit with a sealed lead acid battery.

    KyferEz, I don't mean to be a dick here but I think you should stop "helping" people by advertising your products. MP3car.com is a retailer and probably wouldn't appreciate a competitor advertising on their site...

    Unless you already have authorization by the owners to do so, in that case I really am a dick.

    Anyway, LinuxRacr, if you don't have a battery and the voltage drops below the inverter's minimum input during your crank, then it will shut off. Although, if your battery holds enough charge to keep the system alive even a few seconds you may be able to get through a crank.

    moahdib, just wanted to ask a couple questions, first of all....do you have an invertor, or just a dc adapter......basically i'm asking if you docking station takes an AC or DC input, i know all of the new IBM docks in my office are AC power and dont use the laptop dc power supply. Also.........wouldnt the standard ITPS work as a shutdown controller for a laptop perfectly? I was thinking of using one to regulate power for a LCD in a buddy's car, and using it to controll startup/shutdown for a laptop through a dock.

    "if your battery holds enough charge to keep the system alive even a few seconds you may be able to get through a crank."

    If your laptop is in hibernation mode why is the battery an issue?

    Yes, I do. In fact, they are a distributor of our Power Controllers

    My battery holds 0 charge. Not even a second's worth of charge. It is just there to continue the circuit (extra weight). I have a 400 Watt Coleman inverter and also a DC-DC power adapter that does 19v too that I got off ebay. Now what are my options?
