Computer Not P.O.S.T in car
I have an Opus 150 watt DC-DC Power Supply, Shuttle FV24, 256 Megs Ram, Digitalww 7" LCD, Sound Blaster Live, Maxtor 40 GB HDD, Via 1ghz Nehmia CPU.
The problem I am having is when I turn the car on I have opus to bring the computer out of standby. Everything worked fine all summer, weather has changed a little now and im having problems. If i take the carcomputer in the house it boots up fine, and comes out of standby fine. However in the car, most of the time it wont POST or either if i manage to get it on, it wont come back out of standby. I have not tried hooking the opus up in the house as I have no 12v source inside.
When I turn the car on all the devices that I have hooked up to the opus turn on. The motherboard light comes on, cpu fan spins, LCD comes on, and hard drive spins up.
The car computer is in the trunk, so I dont think its a problem with condensation.
I hada similar prob...my acc (yellow wire to the opus) was not connected very well. Also check the polarity of the green and white wire on that is on the opus that connects to the motherboard. Sometimes if you have moved things around and rehooked this up...you can get that backwords, and it only works right one way.
