Once I went on site to set up a computer for a school. I spend several hours setting up the equipment and configuring all the software and checking the Internet connection. When I left, everything was working perfectly.

The next morning, I got a call from the teacher, saying that the computer wouldn’t turn on. Perplexed, I paid another visit. I sat down at the desk and looked at each component: the scanner was on, the monitor was on, the speakers were powered up, but the screen was blank. I looked under the desk, and, sure enough, none of the lights on the face of the computer were lit. I reached down, pushed the main power button, and the computer immediately came to life and booted up normally.

Me: “Why didn’t you try that?”

Customer: “The light on the brain was on….”

She was pointing to the speakers.
