I'm on a MBP 10.5.6 Intel, 2.4ghz, bought this first quarter of 2008. It doesn't happen TOO often but it is very annoying when it does.. at random times my keys and my touchpad would just stop working. USB Mouse works fine, I can click around, but anything on the keyboard and touch pad absolutely does not respond. I figured out that a quick fix is to close the lid (which puts it to sleep) then things turn back to normal.. this is annoying because wifi/lan disconnects when the book gets put to sleep. Does anyone else have this problem?
