Macbook Pro random "stuck" keys under Leopard
I realize there is a widespread problem with unresponsive keyboards under Leopard, but this is not the same issue.
With a 2.4 MBP w/4 GB RAM:
On occasion, after installing Leopard, upon waking from sleep, my keyboard will suddenly register a key as being permanently pressed, resulting in an inability to do much of anything except listen to the repeated bebebebebebeep of a key pressed incessantly. Sometimes it's the shift key; other times it's a number key, or the Apple key. It has been the semicolon key, the "p" key, and the Tab key. When I open the Keyboard Viewer, it shows which key or keys are being registered (thanks Tech support for showing me that feature). When I sleep the computer again, it sometimes stops once I wake it up again. Other times, it will quickly start happening again and will take another sleep-wake or a restart to function normally.
During all of this, the trackpad seems to function normally.
It doesn't seem to have increased in frequency, though the first few days it happened (around 11/6) it occurred 10x or more per day. Now, it seems to occur about 3-4x every few days.
The keyboard is functioning normally otherwise, and the hardware seems to be fine. (Read: there are no ACTUAL stuck keys!)
I understand it's unlikely anyone will be able to solve this problem, but I'd sure love to know if anyone else is experiencing this after upgrading to Leopard.
Best,
Peter

Same issue here, have been looking to solve this for a while. Although my Macbook Pro is very recent (mid-October), the problem appeared after I installed Leopard, but not right away.
I log in, and the little login window "shakes" and you can hear a beep-beepbepbeep-beeeeeeeeeeeeeeep as if some keyboard input was repeated endlessly. It happens even sometimes after I do manage to log in (by frantically clicking on the "back" button with the mouse on the login window, sometimes it works, sometimes I have to put the machine to sleep...) Sadly, I cannot predict when it will happen, as it sometimes behave perfectly.
So it doesn't happen all the time, just about half the time, and I won't speculate on whether it is a hardware or software issue, it is too hard to assess at the moment, since I use many different peripherals in conjunction with the Macbook Pro, such as Bluetooth wireless mouse and keyboard from Apple, and external monitors (many). The problem happens sometimes when such peripherals are enabled and plugged, sometimes not, sometimes without them, sometimes not...
another link found on the web with the same issue:http://www.techsupportforum.com/alte...petitions.html
I will be posting on the Apple Discussion forums about this too.
Very frustrating.

Any feedback, ladies and gents?
Thank you

Reinstall Leopard.

I have one answer for both of you, and it seems to resolve most all Leopard-related quirks.
Reinstall Leopard.
new here on the forum.
Seems I have the same problem here since this morning.
It started with the up-arrow key, thought it was my keyboard.
After cleaning my keyboard and might mouse, problem still existed.
After that, I connected another keyboard and mouse to my Mac Pro and rebooted.
This time, it was the "+" key. I rebooted, connected the new keyboard and mouse to another USB port and now the "-" key got "stuck".
Funny is, that I have two separate HD's with different installs of Leopard.
The problem exists on BOTH installs.
What's going on here?
Any news about this?
Any help appreciated!
Best
Richard
I too would love an answer here. Thanks!

So it must have been some crud. Hope that helps.
Just happened to me on Lion. 1st time too...
It's doing on Lion OS also. 1st time was today...
Exact same problem here. Number character repeating into infinity, but has nothing to do with the keyboard. Happens just after waking up. Can be debilitating at times. Is Apple working on a patch?

For Leopard? No. Unless that's not what you have.
I started getting this recently on Lion. Due to an unrelated issue I had to wipe the machine and reinstall so I went ahead and put Mountain Lion on, and still experience the same issue. It's definitely hardware (for me at least), as I have PGP Whole Disk Encryption so I get prompted for a passcode before booting and experience the issue there as well. It's unrelated to any physically stuck keys, as I can turn it off, wait a few minutes, and turn it back on (without pressing any other keys besides power) and it will be resolved. I also have tried pressing all keys in a similar manner to what Brugmam did with no change (still have repeating keys).
Luckily I still have applecare for this, so I'll be bringing it in to be repaired today. I'll try to remember to pass on any information if the tech tells me what he finds.
Edit: I didn't fully read the forum link DrSly posted yesterday. I'm glad I didn't end up having time to bring my MBP to be repaired, I finished reading the other forum thread, and a number of people reported their issue was caused by a wireless keyboard. I'm very careful to turn mine off before I drop it in my backpack, but apparently it has been turning itself back on somehow. I pulled it out, it should have been off, but I pressed some keys and sure enough they went to my MBP. I'm leaving it out of the backpack today, and if I don't see the issue I'll assume that was the cause.
I am xumei!How are you? I hope can help you!
