Mac OS X 10.5.2 Special Report: Trackpad, mice, keyboard not working -- reset SMC
Some users have found their keyboards, mice and/or trackpads rendered non-functional by the Mac OS X 10.5.2 update.
MacFixIt reader Chris Rosa writes:
"I'm not sure if this has anything to do with running my MBP (Core Duo) connected to a screen and keyboard, with the lid closed, but following the 10.5.2 update tonight (which otherwise seemed to go great) I found that the built-in keyboard and trackpad didn't function once 'un-docked'. Actually they wouldn't operate at all."
Chris eventually found an SMC reset effective. The rough equivalent of an SMC reset for PowerPC-based Macs is a PMU reset. Instructions for the procedures, respectively, are as follows:

I'd go back to Tiger, but Time Machine has saved my butt too many times already to risk going back.
