For a significant part of my working career I was a tech support field technician for the State of Oregon. Essentially I was the Maytag Repairman for the computers, routers, switches and everything wired into them for my region of the state. A decent job overall; I worked pretty much without direct supervision and got to be out and about at different offices to do my work.
Often people called me directly when they had a computer problem, but mostly my work orders were routed to me from the Help Desk, a central bank of technicians staffing phone lines taking service requests from users. The Help Desk would try to resolve the problem over the phone; and if they couldn’t, they would dispatch a tech (like me) to make an on site repair call.
One day I received a work order from the Help Desk; a user reported that their computer was making a buzzing sound. The Help Desk operator said they could even hear the buzzing over the phone when they were talking to the user. They couldn’t resolve it so I was dispatched to the location.
When I arrived I did my “detective” thing and started to interrogate the user; the usual questions like when did you first notice the problem and what have you tried yourself. As I was talking with the user, the computer buzzed for a few seconds and stopped. I heard it! I started looking at the screen and running a few diagnostics; about two minutes later, it buzzed again, but only for a few seconds and not long enough for me to clearly determine the source of the buzz.
As I sat there puzzled the user quipped “Yes, it even buzzes like that when the computer is turned OFF”. My eyebrows raised significantly.
There, it buzzed again. I began to time it with my watch. At regularly every two minutes (120 seconds precisely) it buzzed for 5 seconds. The computer’s CPU was placed on the floor under the desk so I got down on my hands an knees and put my ear to the side of the computer… looking at my watch, the buzz came right as expected. However the sound now appeared to be coming from over my head rather than from the computer.
I crawled out from under the desk and sat in the user’s desk chair; opening the desk drawer – there in the drawer was a pager. I watched as at precisely two minutes, the pager vibrated and danced around the wooden bottom of the drawer.
The moral of the story is that not all technical problems require a technical solution.
