    Post question for aaron, or anyone, about power switches

    I've read on your site (and on a few posts I searched on) that you have a seperate switch that powers your computer on and off. I'm looking to do the same thing since when i turn the ignition and computer boots up it just beeps once, then continues to beep unless I...
    1. unplug inverter from cig lighter
    2. manually hit power switch on comp
    3. start car, plug in inverter
    4. go back to the trunk and hit power switch on comp

    How do I extend the power button? Or is there an easier way? (the case is AT, its one of the ones with the old school turbo button). Thanks much,
    dave

    Then don't answer.

    I assume this is an AT motherboard? The way I set mine up was to mount a power switch that activates a relay which supplies power to the DC/DC converter. You would probably just want to have a power switch in series with the inverter power leads, tapped off of one of the constant 12V wires. Tapping off the accessory line is no good if you want the computer to continue to run when you start the car as most accessory lines are inturruped as you move the igniton switch...

    With more details of your setup, I could help more.

    Im not sure if this helps or is what you are looking for, but if you just want to extend the power switch...

    Find the pins where your current switch is hooked up to. Figure out which two pins turn your computer on. This is done by simply connecting a piece of metal (wire) to two pins...if the comp turns on...those are the ones. Solder one wires to each of those pins (one wire for each pin) and run them to where you want the extended switch. Hit up radio shack for an on/off switch and connect those two wires to it. And your set.

    If this is what you were looking for let me know, I can post some pics of the sodering job and what to look for.

    I don't know what motherboard and how old it is that you have. You said the case is AT but motherboard is ATX? You mean your power supply is AT? Well, IF you have ATX motherboard and ATX powersupply, on your motherboard you will find pins which are labeled on the board... Mine is about 6 yrs old and have them. Just look at the corners or somewhere abou 10 pins are located. Look closely, you will find the labels....hope this helps.(or is this what you are looking for???)

    Daver i know this is a little to late to answer but still....:-)

    Why dont you just connect the inverter directly to your car battery bypassing the acc line etc (ofcourse you have to cut the plug which goes in the cig lighter) ok now that you have cut the cig socket which has a in build fuse so now we have two wire runnig from the battery to the inverter one is the ground and the other is the positive

    Now you can just add a 30A fuse in the positive line near the battery like the pioneer amps and run the ground through a switch which is very close to you when you driving.

    Now leave the comp switch on forever so you can just power up using the switch near you

    ......

    That works too, as long as you dont have a "soft power switch." But you can solve that problem too...

    Ohh Sorry for being so slow, Ill get those pics up today (hopefully).

    New guy here, can you explain how you would do that. That is for ATX style power buttons.

    Also, do you need a certain OS to use that RC circuit that has been a hot topic on this board lately. The one about using a potentiometer to set a delay time for sending standby and shutdown signals to the CPU?
