Is there a way to turn on a computer without using the case's front power switch?

Hi everyone.

Is there a way to turn on your computer using a the case's front panel switch? I have a case, where I replaced the motherboard and tried two different PSU yet the computer will not turn on.  I do not have another case to test it out in, but I have a feeling the case's power switch might be dead.

But then again I could be wrong. Any ideas?

Thanks!

If it is ATX, the power switch is a momentary switch, i.e. press button=circuit closed, let-go button=circuit open. you can go to radio shack and buy a momentary switch and hook it up. Or the more ghetto method: you can briefly short the two pins on the motherboard with something metallic (careful here, you don't want to short anything else out nearby).

Same goes for Micro-ATX?

have you double-checked that the switch connectors are properly attached to the correct pins on the motherboard?

hint..if there's a  reset button and it works, plug it into on/off and use the reset button instead

check in the manual to which pins your power switch connects and try shorting them momentarily witha screwdriver, as said above. just touching it for 1 sec is enough.

That and.... if there is one, is the switch on the back of the power supply on?

I came across some motherboards, that had a "Keyboard Power On" jumper set, and when that was set, they would not power up normally via the switch. Theoretically one was meant to be able to hold the space bar down on the keyboard or something, but it didn't seem to work too well. Jumper was labelled KB_PWR and was near the keybaord connector.

But if it's just a dodgy switch, shorting the pins will work, or stealing the reset switch, or whatever other switch is handy, I hooked one up to a keylock switch the other day here.

wow who knew you can just touch it with a screwdriver to turn it on? Pretty slick stuff. Learned alot.

The computer has a mind of its own. I tried switching it with the reset button connector and it still wouldnt turn on.

So then when i tried touching the contacts with a screw driver it turned on.

Then when i turned it off, and reconnected the power switch connector, it turned on! what the hell? And i tried with the reset button connector and it turned on again! I think the switch is flaky. I remember it happened before.

About a few months ago I turned it off to move it, tried turning it on and it wouldnt work. I come back to it a few days later and it turns on.

sounds like the circuit board for the switch is going/gone, which is pretty much what you believed to begin with.
new case..or replace switch

you can measure the switch with an ohm meter - just put 2 needles in the connector to measure it.
