Hello, I opened the laptop to replace a faulty fan and when I put it back together the power button didn’t work.

So I replaced power button module cable and still the same.

However, whenever I remove the top cover (the one under the keyboard) it seems to work fine !

I’m puzzled.

Hello, does your computer works if you do not fully place the cover?

Problem solved:

I've cut the grounding ribbon between chasis and power button module and it works find now.

It makes no sense what so ever, but it works.

Thanks for everybody's input.
