Re: Bad design
If I have to look in the manual (absolute last resort of course) it's a really bad design!
One of Apricot's IBM compatibles had the power switch on the back. It was a grey plastic rectangle with a slightly stepped outer edge, just the right size and shape to look like the cover over a 9-pin serial port or similar. I made very sure when I installed the machine that the customer staff knew exactly where it was.
More intuitive was an HP tower with the power button at the top (right next to the floppy eject button - a molly-guard was deployed on our in-house machine). We had a phone call from a customer late one afternoon, bearing in mind this was the days of hard power switches.
Customer : "How do i turn the computer off?"
Us: "Errm, press the same button as you did this morning!"
Customer: "Yes, I know that, but I've forgotten where it is!"
It takes a special kind to forget, in 8 hours, where a power button is when it's on the front of a tower system in the most obvious place possible!
