Power switch pinout?!

2020-08-14, 21:06 PM

I have a Legion Y520T-25IKL Desktop.

And I am upgrading the mother board to a new one.

The problem is that from the power switch there is 4 black unmarked cables. 

I suspect that two are power led and the other two is power switch. And on the mother board there is no indication or markings either.

 

So do anybody have the documentation or know what is what?

 

Attaching image on the mother board and I have circle in the four connectors that is used for the cables.

 

Please help me I am lost here!

I do not have a schematic, but if you could locate a multimeter, or use some other method of testing continuity you should be able to find the switch pretty easily.

Hi! Thanks for the reply.

Good idea. I found it and I think that the other pair is is the power led.

Thanks!
