I run a thinkpad t60, winxp sp3.
Every now and then (sometimes 2-3 minutes, sometimes every 10-15 minutes) the computer will make a beeping sound that is like the "low battery alarm" (although it's connected to AC and not low...).
Also the device connect/disconnect sound goes off at least once a day, although nothing is being connected or disconnected.
Is there a way to check what program is causing the beeping? I've updated virus definitions, scanned for spyware/viruses and there are none.
