The cover turned out to be the plastic bag the mouse was packaged in.
After trouble-shooting for magnets and heat failed to diagnose the problem,
it was found that the customer labeled the diskettes,
then rolled them into the typewriter to type the labels.
A few days later, a letter arrived from the customer along with Xeroxed copies of the floppies.
The customer asked the tech to hold on, and was heard putting the phone down, getting up and crossing the room to close the door to his room.
After 40 minutes of trouble-shooting, the tech discovered the man was trying to fax a piece of paper by holding it in front of the monitor screen and hitting the "send" key.
"Yeah, I got me a couple of friends," the customer replied.
When told Egghead was a software store, the man said, "Oh, I thought you meant for me to find a couple of geeks."
He had cleaned it by filling up his tub with soap and water and soaking the keyboard for a day, then removing all the keys and washing them individually.
The tech explained that the computer's "bad command" and "invalid" responses shouldn't be taken personally.
After ensuring the computer was plugged in, the technician asked her what happened when she pushed the Power button.
Her response, "I pushed and pushed on this foot pedal and nothing happens."
The "foot pedal" turned out to be the computer's mouse.
She said she unpacked the unit, plugged it in, and sat there for 20 minutes waiting for something to happen.
When asked what happened when she pressed the power switch, she asked, "What power switch?"
Caller: "Hello, is this Tech Support?"
Tech: "Yes, it is. How may I help you?"
Caller: "The cup holder on my PC is broken and I am within my warranty period. How do I go about getting that fixed?"
Tech: "I'm sorry, but did you say a cup holder?"
Caller: "Yes, it's attached to the front of my computer."
Tech: "Please excuse me if I seem a bit stumped, it's because I am. Did you receive this as part of a promotional deal, at a trade show? How did you get this cup holder? Does it have any trademark on it?"
Caller: "It came with my computer, I don't know anything about a promotional. It just has '4X' on it."
At this point the Tech Rep had to mute the caller, because he couldn't stand it anymore.
The caller had been USING THE LOAD DRAWER OF THE CD-ROM DRIVE AS A CUP HOLDER,
and snapped it off the drive!
