Clueless User
My most absurd incident involved a customer who was located in an older historic building. They setup a computer so customers could access after hours and download info and pdf's. This computer was located in a supply closet. They were having a problem with the computer shutting down every night. After having our local electric company put a monitor on their circuit and finding no problems, I paid them a visit one day. I couldn't find a problem with the system and was ready to replace the whole box when one of the office staff turned off the light in the closet and the computer shut down. It seemed that the wall outlet they plugged the computer into was controlled by the light switch and the last employee to leave was instructed to turn out the light in the supply cabinet every day. Needless to say I moved the system to a better location.
