Macbook Pro keyboard randomly stops working

Update 3:  I’ll cut to the chase — this update has fixed the problem for me. It’s been several weeks since the keyboard stopped responding.

Over Thanksgiving week, my new Apple Macbook Pro showed up. While it was a refurbished model, it’s the latest generation (model 3,1; aka Santa Rosa) with the 15″ screen using LED back lighting; which is much brighter than fluorescent screens.

Unfortunately, it has already got a problem — the keyboard completely stops working at random intervals, for no apparent reason. Every keyboard button is dead. The track pad and “mouse button” work fine when this happens and the rudimentary diagnostics that allows one to do show that nothing out of the ordinary is happening — no kernel panics, no CPU load…

And, just as randomly as it stops working, it’ll suddenly start working again. Highly frustrating. The only thing’s I’ve found that seam to accelerate it working again are:

  • Put to sleep, then wake up.
  • Reboot.

Apparently, I’m not the only one with this problem (yes, those are all uniquely clickable). The common theme: OS X 10.5, Leopard. And, no, 10.5.1 didn’t help.

Some people reported that fixing disk permissions (!?!) solved their problem. It’s simple enough to do and I’ve got nothing to lose. It did find a few problems; time will tell if it makes a difference. If it becomes repeatable enough, it’s going to the Apple store for a demonstration at the “Genius Bar”.

Will keep you updated…

Update 1: Nope, disk permissions didn’t fix it.

Update 2: Well, Apple acknowledged there was a problem and came up with software a fix. I’ve installed it just now and we’ll see if it really addresses the problem.
