    Opus 120w problem

    Well I've had my carputer in for a few days and I can't figure out whats wrong with it.
    It will power up and run perfectly fine. Until I shut it down. It shuts down just fine too. But after it shuts down it wont power back up unless I unplug the power to it and plug it back in. Then it powers up fine again.
    The opus gives me the 1 blink ever 5 secs before I start it. Manual says that means all is well. After I shut it down and it wont start back up I get the exact same blinking except it is very dim. When I unplug and plug it back in to get it to work i get the full brightness of the led.
    I could put a switch on the power to it but that would be a pain. I would have to run wire to the dash and back(carputer is in trunk).
    Has anyone else had this problem? Anyone know what it is?

    PS Computer runs fin off normal AC psu without having to unplug and plug in everytime.

    I guess if no one has any ideas I'll put a switch in the dash.

    Or is there any kind of hardware that can automaticaly cut the power for for a couple seconds when the ACC is turned off?

    thanks for the reply but I tried that and then it wont even start up the first time.

    I also realised today that the second start up it does get the signal to start and tries but it seems like there isnt enough power output from the opus. Like I said after it shuts down the LED blinks very dimly. Then when you try to start it up again the LED turns on solid but still very dim. I know LEDs take very little power so I dont see why it would ever go dim unless the battery was prettly much dead.

    My idea is that somehow after shutting down the computer the psu power output is changed to almost nothing or it is shorted somehow. But what happens to the opus after power down that would cause a short that would go away after unpluging the power and pluging it back in?
