I’ve discovered the fix to the elusive keyboard beeps which occurred whenever I pressed certain combinations of three (3) keys. Using experimentation, I came up with this rule:
The computer beeps when I press any three key combination all in the same row including at least two of these keys: 4567rtyufghjvbnm.
Some Google searching found me the fix in a ThinkPad mailing list. At first, I thought they were talking about Linux. But no, it was Windows, and yes, it worked. Another person blogged it too (the original link to his blog was broken, so I feel it is especially important for me to blog it and clarify the instructions). Here’s what you do:
1. Open the Device Manager. You can do this from My Computer -> Properties -> Hardware -> Device Manager.
2. Show Hidden Devices. You can do this from View -> Show hidden devices. This is where I was stuck: I didn’t know the Device Manager had hidden devices.
3. Under Non-Plug and Play Drivers, open the properties for Beep. Go to Driver -> Stop, and the beeping will cease. I think you can also Disable the device, but for me, this would require a reboot.
I believe the Beep device is the most stupid device ever invented. It’s really the stupidest. It serves only as an annoyance, in very strange instances. And I’ve only seen this on the ThinkPad, after using lots of other computers.
Can anybody explain to me why this beep even exists?!
Anyway, I hope somebody found this interesting, or maybe, if you had one of the beeping ThinkPads, found it useful. I’m on a Z61t by the way.
Update: I reinstalled Windows Vista on my ThinkPad and had the same problem again. The steps are similar, but here are updated Vista screenshots to ensure nobody’s confused on what they’re looking for to fix this. Sorry for the low quality, but Microsoft Paint doesn’t compress images very well.

Make sure you select “Show hidden devices”.

There’s that dreaded beep, listed under “Non-Plug and Play Drivers”.
If you’re interested in Sun exam training, the 310-200 is a very common course. Additionally, the 350-001 as well as 350-030 are comparatively difficult. They are the prerequisites of 640-801, which eventually leads to 640-816.



Thank God for that. You’re a genius Cheers, Philip
it’s a miracle, thanks so much
THANK YOU!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! This thing has been one of the most annoying parts of my laptop and now its fixed
This does solve the problem of the beep sound, but there’s a deeper underlying problem which caused the beep. When those beeping key combinations are pressed after the above fix, the key combination is still disabled. So Up-Right-Space works, but Up-Left-Space doesn’t. This is probably only an issue for games, but can be rather annoying…
Anybody got any ideas as to how to fix this underlying problem ?
Heck yeah! Sometime the internal beep is listed under the Windows volume control, but no joy until I finally got fed up and did a Google search…
