Hi Everyone,

I need a bit of help :) I was just curious and wanted to see what that PC looks like inside. Unfortunately when I took out the motherboard, a plastic piece of the power button (the one that was touching the button on the chassis) snapped. Now the piece that is left inside doesn’t move, I assume it’s stuck in “pressed” position.

From what I can see, that entire button is integrated with LED light, there are 5 pins on the other side of the motherboard. What are my options? Is it possible to leave that button to not go into soldering on the motherboard and just solder something into that existing one? Or do I have to remove it completely?

The hole in the chassis is 9mm wide, maybe I could remove the existing button, solder two cables onto the motherboard and install a totally new power button into that 9mm hole then connect with those cables?

How to measure those 5 pins to find pins that are responsible for powering up? I assume, once found, that I can just short them just like 2 power pins on standard PC motherboards when I was using a screwdriver to power up bare motherboard?

Thank you for all suggestions.

Before doing anything try to determine if the switch still works.

Does pressing button (yellow area) of the switch turn the PC on? Press using a non-ductive material and press very carefully.

If the PC turns on that is good. Just remember to use the normal Windows shutdown icon to shutdown.

Objective being to determine if the existing switch still works.

Also add a photograph of the broken plastic piece.
 
The button is permanently pressed in, so when I plug in the cable it turns on the PC. I can't take a photo of that piece because it broke to pieces, it was like a plastic ring around that red LED light. In the worst case scenario, I can just turn on the PC by plugging in the cable every time, but that is not a permanent solution really and would prefer to get a proper power button.
