I was just chatting and surfing the web when all of a sudden the mouse wasn't moving, totally frozen, couldn't move at all, so I connected my external mouse and that one worked, but when I tried to google the reason for this random mouse freeze I noticed that the keyboard wasn't responding either. Rebooted and now everything is working fine. Searched here for a similar problem and found only one or the other. I have an early 2008 MBP, no problems with it whatsoever, except a replaced battery about a month or so ago. Any ideas? suggestions?
