motherboard flambe (Score 1)

I am tech support for roughly 600 users, and I noticed that I was getting a large number of fried serial ports (thus, motherboard replacements) on a certain type of pc. When I checked, every pc with a failed port had a Palm on that serial port. Not all pc's w/Palms fried of course - but when, out of 600 pc's, every bad serial port has a Palm Pilot attached to it, I get suspicious. And yes, hardware-identical pc's had devices attached to the serial port and yet did not lose the port. Hmmm... To date, I have ONLY lost serial ports to Palm Pilots.
