    skippy911, macs don't hibernate, only sleep. Sleep doesn't draw much power at all so I wouldn't be concerned.

    The P1900 does NOT come with a power cable for the mini, you have to cut your stock Apple power adapter. You can put Molex ends on it so that you can use it in the car and in the house.

    http://www.carnetix.com/p1900/P1900P...ini/index.html

    The reason I am getting a powered usb hub to be controlled by the P1900 is that I have USB devices that are always on, exp USB touch screen and USB GPS, its these devices not the keyboard/mouse that wake the mini up from sleep. If the P1900 detects that the mini is not asleep 1 minute after shutting off the ignition it cuts the power to the mini because it is drawing too much current. That is why it is important that it stay asleep.

    So the touchscreen and gps wake up the mini even after the car is off? Thats crazy. I plan to have the mini in my car in a dock like bugbyte made since I also want to use it in the house. I will have usb gps, usb touchscreen but thats about it for usb devices. I plan to use the dualboot to switch to windows if I ever want to use the gps, else ill use the mac side for the music and such. Did you get the special thing carnetix makes to add a 3rd output? I amthinking of getting that since I want to power my gps/ts, monitor and mac mini but I dont want the mini to keep waking up.

    Skippy, yes they will wake it up and that will cause the P1900 to power off the mini. The P1900 simply tells the mini to go to sleep with the mini power switch cable, it will also wake it up when you turn on the ignition. You might want to put a valet switch inline from the ignition to the P1900 so it doesn't always power on.

    Connect the wires from the switch to the Green output on the P1900 and the Second Ground (Black).

    This is how you open the mini:

    I just got the 3rd output addon from MP3car and a powered USB hub from newegg the other day, haven't had a chance to install it yet. My primary output on the P1900 drives the mini, the second my Xenarc 7" touch screen, and the third will power the USB hub so it only gets power when the ignition is on, so no chance of waking up the mini when its sleeping with the ignition off.

    I put a molex connector, the kind you would find on an internal harddrive or cd rom in your computer so I could use the mini inside the house and in the car. An adapter with at least 6 pins would be best because because there are 3 wires to power the mini, and the other 2 for the turn on cable.

    You can get molex connectors with more pins from www.mouser.com like this one

    Could you throw up a few pics of the power connector you made? That sounds like it would work perfectly. Also I heard there is a way to open the mini using wires instead of a putty knife since the knife method can fudge up the case. Any idea where to find that? I google but found notta.

    EDIT: Found the wire method looks like a real PITA hehe.

    Well, it's crazy for your car. Remember that the Mini is not designed for car use. The wake on USB activity is so you can touch a key on the keyboard to wake up the machine. Or like on my Apple monitor, there's a wake up button. Very convenient IN YOUR HOUSE where it doesn't matter if the computer wakes up unexpectedly. In the car, different story.

    You can keep this from happening by carefully cutting the 5 volt supply wire in the USB cord to your powered hub. Then your USB devices won't have any way to operate when the computer is off and won't wake it. When you start the car, the hub will power up the devices.

    If you're worried about screwing up the case, put painter's tape (that blue masking tape) around it when you open it so it doesn't scratch. I've opened mine twice with no problem.

    I have to say that even though the USB devices remain powered (ahem, just like on the Via Epia boards), the sleep feature on the Mini is the greatest improvement to my system since I switched to Mac. It awakes instantly and is playing music in 3-5 seconds. I usually haven't buckled my seat belt and put the car in gear before it's on.

    Unfortunately, you have to buy another power brick if you want another connector. Search this forum for a source. Someone posted a link on it awhile ago. I got mine for around $45.

    In sleep mode the mini draws very little power, you should be good for at least a few weeks with it in sleep mode.

    If you're worried about it, you can reprogram the P1900 to cut off at a higher voltage, or you can use the Sleep Timeout program to limit sleep to just a day or so.

    I haven't done either of those things and usually sleep the Mini over the weekend after work. Haven't had any issues.
