If you are IBM Thinkpad user (T60, probably other models too) you know all too well how annoying the system beep can be, specially when you are on headphones (the beep always comes at the highest volume totally stealing my concentration). Usually comes when you press multiple keys at time, but once in a while it beeps randomly. Easy fix.

Go to Device Manager, Show hidden devices, Scroll to the Non Plug and Play Devices and disable the Beep device.

This was the only problem I was having with the laptop, and now it’s gone! Best laptop to date I have used.
