Dunno where to put this tbh.
So the other day I was going through my thinkpads. No real reason, just had 5 minutes to clean a little while I took a break from studying. My L520 popped a fuse when I tried to do a screen upgrade, and my T420S has its backlight circuit out for some reason.
Where would I look up board schemat’s for thinkpads? Are they available?
