I searched everywhere the only thing I found is that there’s a reset pin right behind the usb port you trimmed off. Hopefully someone else has the info you need

Is this test pad here not the reset switch line?

It's in almost exactly the same position as the 79001 reset pad

Well i did solder to that point and still no power

I thought that was the pin but wasn’t sure about it.

Did you solder a regular tact switch to it to test? Or did you wire it to the lid switch?

 

[arne]

solder to lid switch

solder to lid switch

Try using a separate tact switch, or if you don't have one handy just solder a wire to the pad and touch the other end of the wire to a ground location to simulate pressing a button

Ok I will do this

I solder the tacktile switch still no powering on . I checked with mulitimeter there is 0.225 v on that ponit when i press tacktile switch it gonig to 0v when relasing come back to 0.225v what does that even mean

I do have the same mainboard here with all chips removed. The RESET input pin on the Mechacon is G3 and from that pin I traced it back to the test point I marked in the image below. I verified it by measuring the continuity to the tact switch on the front power board, sadly I don't have a working version of this exact mainboard to confirm for you.
