Well, I'm still waiting on my main techie guy here at work to get back to me on the problem, but in the meantime one of the other guys here gave me a pretty decent solution.

Here it is:
Use the P1900 in its normal sleep mode operation. This will keep the mini in sleep mode drawing a little bit of current when the car is off. Instead of running it like this all the time, set the computer to turn off at a specific time every night. For example set the cpu to turn off at 12:00 midnight or whenever you usually put the car away for the night. A specific shutdown time can be adjusted in the system preferences/energy saver. This would at least conserve some battery power. Your mini would shutdown at midnight and the next morning startup whenever you hit the ignition. This is about 6-8 less hours of sleep operation per day. It's also useful incase you forget to turn your cpu off and go on vacation. It would automatically shutdown at midnight.

I might run it this way for the time being before someone figures a permanent solution out.
