One of the programmable buttons on my mx518 v2 has become completely unresponsive no matter what I try, so I'm pretty sure it's a hardware malfunction.
Else than this, the mouse has worked flawlessly since 2010.
No improvement after a good dusting and alcohol rub on the circuits+connectors, which is about how far my expertise goes.
So how do I even begin to troubleshoot this?
I do realize it's game over if the PCB itself is bust, but if it's a simple soldering job I'll just swing by the EE students' workshop at my uni.
Also didn't realize it was discontinued until last night when I started googling, but I'm a poorfag anyway so would much rather put some effort into fixing it instead of replacing.
Take mouse apart and use drop of contact cleaner on switches

Fixed it!
Didn't find the error at first since I initially didn't wanna plug it in with the hood popped but figured wth, for science.
Somehow the distance between the plastic button and the actual switch had gotten too big over the years (wear?) and a tiny piece of electrical tape on top of it was enough to close the gap.
Fingers crossed for 7 more years with this absolute madman.
my 2006 mx518 is still going strong

Yeah it was probably wear
I had the same problem with the right mouse button of my razer mamba. The plastic that presses on the switch had a notch in it. I filed it flat so that the notch was gone and it worked perfectly fine again.

I've already allowed mine to retire and moved it to reserves. I'm planning to do the same to my G400 this year.

Could be plastic worn away, could be the spring inside the switch needs stretching to help decompress after years of use.

>build quality lasting the average /g/entooman over a decade
not hard to understand why they replaced it with the shitty g400
pic kinda sorta related: my dad bought this beast for his company back in 1993 and except for a few jammed papers it's been going strong almost daily ever since
