    Newer cars have built-in shutdown controllers?

    So here's my thoughts. . . .

    When I turn off the ignition on my explorer, the windows still work. Why not run the "sensor" lead off my relay powering the carputer/screen to the power supplied to my power windows? Apparently there's still power there, until the doors open.

    Thoughts anyone? This might be a great idea for us "CHEAPOS" out there. Thanx!

    You wouldn't even need one off the ignition, as the power to the windows would come on with the ignition anyways, right?

    I already do that with my 1999 Buick Regal. The radio is actually on the same circuit, so I use the accessory line to toggle my Opus. I turn off the car, even take out the key, and the computer and stereo stay on until 5 minutes pass or until I open a door.

    awesome! How often do you find yourself waiting to open the door? Do you sometimes give it a hard shut down by opening the door too soon? My shutdown time to hibernate is about 8 seconds on average. That's probably about how long to pickup your crap and change your sunglasses back.

    heh heh, yeah. It's great for listening to the end of songs, etc. It's rare nowadays that I open the door prematurely. If I want to keep the puter on, say, while I'm at a gas station, I just switch the key to accessory. The engine is off, the ignition is unpowered, power is never interrupted to the computer so it stays on.

    I liked that idea for about the first day, then my passenger opened the door and killed the power to the PC as it was hibernating/shutting down/something then ran checkdisk on the next boot up. Not good.

    Well, that's different then mine. I use direct power to the battery, then the accessory line signals the opus to shut down. You must be using an inverter setup, Curiousity?

    The Opus is great. I open the door, or the passenger does, and the computer automatically begins the hibernation process. And the Opus provides power until it is done.

    Oh, I thought you meant ACC would cut the power to everything. That's kinda what I tried but then switched to ACC sensing in the PC, so it's about the same as what you have. The amps are switched by ACC as well, so I get sound until the door opens too and no problems with glitches from starting or switching the key back.
