I fried the CPU on my laptop a few months ago, called an "overnight" repair service, and got my laptop back a month later. Lotsa stuff didn't work, so it had to go back into the shop a couple of times. Then, I found that I couldn't get onto the net through my wireless hook-up. Called 'em again and they send a techie out. He piddle with the laptop for a couple of minutes, then asked me if I had the necessary codes.
A friend (who has written books on wireless systems) had set the wireless system up for my wife and me in the first place, and when he finished, he gave me a whole list of passwords and code numbers, which I wrote down in a notebook. He admonished me, "Don't lose this!" So I filed it away carefully.
When the techie asked for the codes, I sez, "Just a sec," and dove into a desk drawer. By the time I came up with the notebook and started to hand it to him, he said, "That's okay, I don't need it now. I hacked into it."
Really makes ya wonder! I guess stone walls, drawbridges, and moats just ain't what they used to be.
