Problem is that the cursor freezes and the keyboard in the middle of the game, but not disconnect. I've checked and the batteries for both of them. I know i'm not the only one with this problem i've had a friend with the same problem. Any idea how to fix?

Subb,

If you have a wired keyboard you can test, you may want to try that. If it works without issue, then most likely the problem is with your keyboard or wireless interference.

I thought of that and checked to make sure batteries were in/ everything was connected and it was, Also my friend plays on a laptop so any thoughts for him? This isn't a common occurrence at all happened randomly yesterday for both of us, Might have just been a problem with the server i'm not sure. Restarting the computer worked for me, as for him it went back to normal once he died.

Did you alt + tab? Cause it happens to me when I do that.

No, my friend was using his laptop, with the default keyboard and a wireless mouse (Neither of them were working) no antivirus or window update for me or him. According to him he did get a bug splat error but didn't fill it out apparently :/. We live in the same area but it happened a long time apart (4-5 hours) and it hasn't happened since

Pressing alt tab / ctrl alt delete didn't do anything, and it didnt say computer not responding either.

Happened to me once, mouse stopped responding altogether. Worked outside of LoL, but not in the game. Had to ALT+F4 and come back after some minutes, there it worked okay
