Mobo wont short on.

[davste07]

Hey all.

So I'm a having a problem with a friends MOBO, it wont post/turn on. I have tried shorting the power switch pins but nothing. The mobo has its led lit, the psu is fine, the cmos battery is brand new. The only way I got the system to power was by shorting the green and black wires on the 24 pin connecter when it was connected to the mobo. However that isn't a soft power so it didn't post.

I'm guessing there has been a short on the mobo and something has died along the power switch area, but does any one know how to turn on a system other than shorting the pins?

Thanksss

How old is the motherboard? Is it still under warranty?

Annoyingly it was second hand... so in the UK they won't do anything! 🙁 I've tried everything, I think it is just dead! Unless anyone knows the circuitry and can help me find if it shorting somewhere.

Your quite certain the power switch on you case is properly connected to the system panel pins on your motherboard, or the wires from the power switch are not damaged?

If you were really brave you could try the re-flow method to fix it.

Yes, I've tried two cases, and also shorting the pwr switch prongs on the mobo it's self. What is re - flow method? I will try it, got noting to loose.

Although i've never tried it and probably never will, reflowing a motherboard means to bake the board for a short period of time in the oven, or using a heat gun, to very gently heat broken or cracked soldering joints to it's melting point so it will "reflow" back together. If you Google "reflow repair" you will see many videos and articles about this method.
