Notebook Mouse 3000: Buttons removed

Thank you! I like this mouse very much, but the left button microswitch stopped working gradually. Now that I found a cheap 'donor' I proceeded to fix the mouse with this help.

But a little pin, shaped somewhat like a little black plastic spinner, felt from the mouse and i don't know where it goes. I think I can see it in image 16 laying just between the circuit board and the screw socket you can see on the bottom left. What's this?

My husband and I have both used this mouse and have not had any problems. He insisted on paying $10 to $15 more than the other brand they had at the store. I think we've had them for close to 4 years now.

I haven't had much luck re-assembling electronics items I've taken apart. With the exception of my Palm Treo, typically the process of disassembly precludes returning the unit to operation.

That said, if the item's been very carefully disassembled, it's possible you have a chance.

As for determining which component has failed, that will likely prove much more difficult.

Good luck, though!
