Macbook Pro Keyboard Issues

I have a Macbook Pro that I purchased in June, and I just upgraded it to leopard using the Archive and install method, and I must say I love the new os. However I now have an intermittent issue with the keyboard and trackpad where both become unresponsive and i have no choice but to connect an external mouse or restart the computer. It's really strange as I could be typing one moment and the next it doesn't recognize any keyboard input. This seems to be most prevalent when the computer is returning from sleep. I have been reading the forums and it seems for some people this was due to a incompatable kext but I have searched my system and I don't have the kext that seemed to give them the trouble. I have also checked with my cousin who recently installed leopard on his 17 powerbook and it seems he is having the same issue. Any help with this would be appreciated, thank you.

Macbook Pro (SR), Mac OS X (10.5)

I have the exact same issue. The keyboard will stop working and become unresponsive- the caps and num lock lights wont even turn on. Then after a few minutes, it turns on again and is fine until I let it sit for a while

I'm having the same problem, but I've never had the patience for the keyboard to return. Always rebooted. Doesn't seem like a feature.

I have the same issue with intermittent keyboard unresponsiveness -- but I'm on an Intel mini. Hubby's had it on his MBP too.

Same here. This is on a MacBook Pro that I bought about a month ago. Now with Leopard the keyboard and trackpad stops working at completely unpredictable moments. The only thing that helps is to connect an external keyboard/mouse and reboot.

I have no weird extensions or software installed. This is basically a clean Leopard install with just my favorite applications added.

Looks like there are a few of us in the same boat. I would like to know what kext chris_kle refered to that was giving other people problems. At least it would be worth a try getting that fixed.

The systems specialist in my office said it sounded like the keyboard driver was probably crashing and resetting itself. Even if this is true though, the knowledge alone does us very little good.

Check Console.app to see if you can find any messages that say what has happened. If a driver crashes, then most likely it will write something that it has crashed or is restarting.

Try removing all USB devices that you have. It seems the OS is having trouble with one of them, possibly a USB datastick or something.

I have no USB devices connected to this Mac.

The USB Bus mentioned in the log files, 0x5d000000, is the internal one to which only the MacBook's Keyboard&Trackpad and IRC Receiver are connected. You can see this with System Profiler.

Here is the kext I had read about from the other threads for you
Quote:

"I also was using SideTrack... I just deleted sidetrack completely and now keyboard works... Here's the trick -- make sure you completely remove the following directories then perform a restart. Good luck!

/System/Library/Extensions/SideTra ck.kext
/Library/PreferencePanes/SideTrack .prefPane
/Library/StartupItems/SideTrack"

This doesn't help my situation though because I don't use logitech mice or keyboards.

I have been having the same problems with my macbook pro. Sometimes it will be waking from sleep or just from leaving the keyboard for a while. The keyboard won't respond and the num and caps lights wont even turn on. I called apple and they said they have not heard of that problem. I hope they come out with a fix soon.

Same problem here. Super frustrating. Three day old macbook pro updated to leopard. I'm getting keyboard freeze at unpredictable intervals. Restarts seem to make it get better, but thats not an option. It really bugs when I'm in photoshop and the clone stamp wont work.
