I had the same issue a few years ago. After spending forever looking for a solution online, I found a fantastic video that explained the reason for this degradation: https://www.youtube.com/watch?v=v5BhECVlKJA

TLDW, it has to do with some components (the contact plates) being rated for electronics of the 90s, with higher voltage than today’s devices use. So these components are now subject to below optimal voltages (say, 1.8V or 3.3V), and tiny sparks happen that would not be there at 5V, thus damaging the plate ever so slightly.

Immediately after watching that video, I opened my mouse and scratched the plates with a flat screwdriver. I haven’t had a problem since then (it’s been a couple of years). But if it happens again I know exactly what to do to save my beloved G302.

Also, fuck OneDrive.

When you put it like that, it sounds very much like theoretical physics

Bird scientist? Are you an ornithologist? Or are you a bird wearing glasses and a labcoat?
