Keyboard & Mousepad not responding

I had the same issue, and would like to confirm that it appeared immediately after I enabled automatic backlighting on the keyboard and disappeared as soon as I disabled it.

Re: switching off "Automatically adjust brightness" in the Displays pref pane... okay, that didn't last, although my battery did not die overnight since I made the switch. (which it has been doing for 4 months!)
Now when I press the F8 - F10 keys, I get (intermittently) the backlight indicator, but with a zero-slash beneath - meaning "unavailable", one assumes.
Also, I'm now back to my earlier conclusion that it doesn't matter which key I'm pounding on: eventually, the keyboard comes back to life. F6, T, Q, whatever.

My resolution came with switching off 'illuminate keyboard in low light conditions' on the keyboard prefpane. I would give that a shot.

Hi,

It looks a Leopard bug to me also.

I've reported it to Apple, please do the same, so maybe they will fix it soon.

Here are the URLs to report a bug with Mac OS X:

Thanks.

I have a MacBookPro3,1 running 10.4.10.

This issue started occurring for me shortly after I installed the MacBook Pro Software Update 1.2. Related?

This does not appear to be necessarily related to Leopard - but the software update may contain some bad logic that also exists in Leopard.

My install is fairly stock, so I don't think I am having any 3rd-party s/w issues.

having the same problem macbook pro 10.5 keyboard locks but touchpad is fine. no externals. turned off backlit, spaces and auto adjust brightnes. I do notice the IOReg_sp and system log is modified every min.
from the system log:
Nov 6 00:09:02 Macintosh-2 com.apple.launchd[1] (com.apple.dyld): Throttling respawn: Will start in 60 seconds

Call me crazy, but it seems as though upgrading to the latest iTunes and Quicktime (available through Software Update) has solved the problem!

An iTunes/Quicktime update would not have solved the problem. Most likely, the fact that you restarted your computer simply gave you a temporary reprieve.

I believe I was on track with my earlier post--the issue does seem to be related to the auto-illumination feature of the MacBook Pro (that is, if you have one). Turning off the backlight doesn't help--at least, it didn't for me.

If hitting F8 a couple of times doesn't help you, I have one further suggestion: try pressing both hands to the speaker grills--that'll trigger both light sensors inside and hopefully unfreeze your keyboard. As far as I can tell, if one doesn't work, the other will (sometimes it takes a few seconds).

It's just a temporary solution--all I can say is that if Apple is waiting on 10.5.1 to release a patch for this issue, I'd seriously like to smack the person who made that decision. A decent company would be falling all over itself to push out a patch if it heard its customers crying, "We can't use our keyboards! Help!" It's simply not right.

I don't blame you for being an unbeliever. All I can say in rebuttal is that all is well since those recent software updates.

An unbeliever in what way? This is software (and very basic software at that) that we're talking about here, not a religion. 😉

My problem is that the lighting up of all my keys doesnt work and that brightness and volume and num lock dont work either. REALLY ANNOYING?
any suggestions?

If you're simply saying that your keyboard works fine, but your F-keys don't, then you may have accidentally checked the "Use all F1, F2, etc. keys as standard function keys" box located in the Keyboard & Mouse preference pane. With that box checked, you'll have to hold down the "fn" key located on the bottom left of your keyboard to use the other functionality that Apple built into OS X.

Using sidetrack????

Okay okay, I'm crossing my fingers here because I think I found a fix.

I noticed when I had my external mouse (apple mighty mouse to be exact), my keyboard woes went a way. So after many days of carrying around my mouse everywhere I figured... well if I'm using my keyboard but not my trackpad, the problem must be with the trackpad driver.

After much tweaking, I noticed that disabling the "Ignore accidental trackpad input" option in the system preferences seems to fix all problems with irresponsive keyboard and trackpad.

I really hope this isn't a fluke and continues to work. And I hope it works for everyone else as well because I know how un-useable our MacBook Pros have been because of this bug. And of course I hope 10.5.1 completely corrects it.
