Broken Computer

When Barb was looking for a dentist to replace her crown cover, she found that her computer wouldn't come on.  She was very upset because her computer had been working fine last night and nothing had happened.  Somehow I figured out that the light switch on the wall turned off both outlets in the wall, the one for the lamp and also the one for the computer.  So now we know that we have to leave the wall switch on and turn off the lamp with the knob.
