    I want my pc to come on with a toggle switch

    I am running desktop pc hardware with a dc to ac converter. I plan to put a power (toggle) switch inline on the inverter power wire, leave the inverter on and just use the toggle switch to turn it on/off. But you know these newer pc's, once the power current is turned off, you have to manually hit the "on" button to turn it back on. How can I wire this pc to "stay" on and just use the toggle switch? (The power switch on the pc has 5 or 6 wires, so I wasn't just going to jump wires to accomplish this).
    I saw no threads on this...

    On most modern machines there is an option in the Bios for what to do when it has a power failure. You can usually choose either "last state" or "power on".

    Yeah, I see that option on my home pc. But I will be shutting windows down before I turn the toggle switch off, in which case the pc will not power up/boot up when I turn the toggle switch back on.
    So I need to somehow hardwire it "on" ?

    It shouldn't matter that you shutdown windows. The BIOS will still recognize that it lost it's power source. As long as you have it set to always turn on when power is restored, you should be fine.

    Wire the toggle right to the 'pwrsw" (or like... power switch) on the motherboard. That way when the computer is on and you throw the toggle, it'll start a windows shutdown. When the computer is off, it will boot up normally (you could always et it to hibernate) However, it will keep draining your battery in such a set up.

    See this thread for my soulution (I want the same thing but I'm using a 12v input PSU) Note, the CNX-P1260 can be found here: CarNetix
