Hi, I have a slight problem with my 17" mid-2010 i7 MPB. Twice (once when the machine was about 3 days old, and yesterday), the machine has decided that it has a numeric keypad only (i.e. M = 0, JKL=123, UIO=456, 789 = 789, nothing else works). The problem is, as I understand it, my machine isn't meant to have such a mode. The first time this happened I was very new to Macs, so the only solution was to do a forced power down and reboot. Yesterday I discovered that an external USB keyboard worked and allowed me to do a "proper" shutdown. 1) Does this sound like a software or hardware fault? 2) Am I accidentally invoking numeric keypad mode with a key combo (and if so, what is the magic combo to exit the mode)? 3) Has anyone else had a similar experience. When I reported this to Apple originally, they had no idea what might have happened, and just had me reset the PRAM (I think - it involved an awful key combo during power up).
