    power up opus without car started

    i'm planning to install my carputer with an opus 150w and get connected/disconnected with the ignition key. But i have question, is it possible to power up the carputer without having the car started?

    regards

    Are you asking if it's possible to start the PC without the engine running, or without the keys in the ignition?

    sure its possible, simply bypass the ignition by an Switched wire. But the big problem is, you could forget to turn the switch of, so your pc emptys the bat.

    a try to show the wiring plan:





    .../-----perm 12V---------\
    bat -----ignition-----------PSU
    ...\------Switch-------/

    / & ---=Wire

    It should, however it may not shut down soon enough in some cases. My Opus 150W has drained my battery a few times. It did shut down during low voltage, unfortunately by this time there wasn't enough juice left to crank.

    Plus, the 5VSB rail is always on leeching power. Depending on the power used by your USB devices, you may want to disable the rail when the computer shuts down (see the relay mod post for the 150W or set the jumper on the 90W).

    I killed my first battery because of a combination of the above.

    hmn...you could set a momentary switch that sends a signal to the opus to turn on, and set the jumper on the opus to 30 or 60 minutes so it automatically shuts down after this time unless you hit the button again or actually start the car
