I currently have a problem with my MacBook Pro where the SMC keeps getting screwed up and needing to be reset. The result is always that my keyboard and trackpad become useless, and I have to use an external keyboard and trackpad.
I took it to the Apple Store and they just reset the SMC, which seemed to fix it, but within a few hours it happened again. I was once or twice able to reset the SMC myself with an external keyboard, but the latest time it happened (always within a short time of the last reset) I could not get the key sequence to work using an external keyboard (and obviously the built-in keyboard is useless!).
This is really aggravating. Is there anything that could be causing this?
