Keyboard & Mousepad not responding

Just having read through this thread, I re-set my PRAM in hopes I can finish some clients work in word. Yesterday my first issues after a leopard install was my iChat (a message telling me another application was using my camera). That wasted more of my time trying to locate what app was using it, which none were, go figure because photo booth worked fine.

Today was the mouse issue, I have a wireless intellimouse explorer, it was acting like the batteries were about to die. Now the keyboard, that drove me nuts, whilst in the middle of typing out a 12 page MSJ in Word, in parallels every apostrophe was screwed up when I printed my document, and I about had heart failure.

In either case, the PRAM didn't fix this keyboard issue, not impressed and wished I had waited to install leopard. BTW my iMac is only 10 days old, and things were running fine before yesterday.

I'm having the same problem, most times it solves itself, once I had to reboot. Just got a MBP on Saturday and installed Leopard right away. Have many been OK with Tiger but now having problem with the new OS? I'm just concerned it might be hardware not software.

I have the same problem with a Mac Pro - after Leopard keyboard and mouse stops working or sometimes it acts like a key is stuck and just keeps typing letters. The system didn't even recognize the keyboard or mouse several times before installation once I rebooted under the Leopard install DVD, I had to reboot the machine several times to get it to work. Now that leopard is installed it worked at first and then didn't work when I rebooted. I am using Apples new thin USB keyboard and USB mouse. What gives???? Pretty disappointing to say the least.

This suddenly happened to me last night during a class I was teaching. I ended up using a USB keyboard to continue. I've tried resetting PRAM, booting into Safe Mode (holding shift key down on reboot) but nothing seems to help.

Interestingly, I rebooted from my firewire backup drive into Tiger 10.4.10 and the keyboard and trackpad work just fine. I believe that it is a Leopard software problem. I have not yet tried reinstalling Leopard.

Out of curiosity, did you do an upgrade, install & archive or a clean install? I updated from Tiger 10.4.10.

I just found at least one potential cause of the loss of keyboard under Leopard. If you have SideTrack installed (touch pad enhancement) it will disable the laptop keyboard.

You can go to http://www.ragingmenace.com/ for the information.

I've removed the files referenced on the site, but have not yet attempted a reboot to see whether the problem is gone.

BINGO!!! Elimination of SideTrack resolved the keyboard issue, at least for now.

Have the same problem here, got a MBP 2.4ghz and keyboard is just not responding - works for one minute then cuts out the next, only key that works is power button... This is totally unacceptable!

I think I figured out the problem, at least on MacBook Pros. If you've got your keyboard's auto-illumination feature turned on and your keyboard freezes, just tap the F8 key a couple of times (ie, toggle the backlight on and off) and see if that restores keyboard functionality.

I too have the "keyboard that intermittently won't talk to the MBPro" problem, since installing Leopard. The trackpad always works. Repeatedly tapping on ANY KEY seems to get things back on track again, although I've had to do so as many as 53 times (!!) before the last keypress makes a character appear on the screen.
It will work fine until I use the trackpad. Then, when I go back to the keyboard, I have had to start again with the keypresses. Just now tried the F8 key: no go. But so far (twice out of 2 tries) F10 is restoring keyboard function.
Hey... I just turned off "Automatically adjust brightness" in the Displays pref pane, and the problem is (so far) gone!

Same here. My Macbook Pro is 3 days old, and this intermittent keyboard freeze started happening today. I hope a simple software issue with Leopard is to blame, since I'm located an hour and a half from the apple store....

I started experiencing this on my MBP today, just the keyboard though.

By the way, I did an erase and install when I upgraded to Leopard.

Just switched my wife after years of trying.
Brand new MBP running Leopard and it's just about unusable because of this issue right now.
I couldn't be more disappointed...
Please Apple.... Fix this one quickly.
josh.

Same problem here. The keyboard randomly cuts out. Strange thing is, everything was perfectly fine until today, and I have been running leopard since release day. No problems under Tiger. And there seems to be no apparent logic to when it cuts out and comes back.

Hey,
I tried booting in safe mode and deleting the sidetrack files manually but there is no sidetrack files there. My keyboard buttons for brightness, volume and numlock still do not work on leopard. I am new to macs, really disappointed with Apple. Will they be releasing an update soon? Anyone got any ideas...
Might take laptop to apple seeing i still have a 3 year warranty.
Thanks.

Also i do not have any sidetrack files on my computer so i doubt it was even installed on my computer when i got it. This problem must not just with with Sidetrack but also with LEOPARD!!! APPLE READ THIS AND FIX IT PLEASE!
