Thread: I want my pc to come on with a toggle switch

na its 2 wires, usually named POWER SW or PSW

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.

OK, I'll try it...

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

OK, dumb question , please answer it anyway. How do I get in the BIOS again. I tried the F2 key on boot up and the the delete key, I just plain forgot

How will it drain the battery if the pc is turned off? (and monitor)

modern power supplies suck juice even when off... they do it for features like WOL and keyboard power-ups.... hibernations is the same
