Don't do that. The user's manual is wrong. We all know by now that the Plus has a feable power supply. > * I have not installed a fan. The Mac is not sold with a fan, > therefore I expected that I need not purchase one. Be sure that you don't block the vents on the top, OR the vents on the sides. Avoid a sunny window on hot summer days, etc. A fan is noisey, but it should extend the power supply life you are getting. I bought my Plus about a half year after they came out. Still on the original analog board, still on the original battery, no fan, I turn it off if I am not going to be using it for a while--say, more than 40 minutes or so. I never leave it on over night or when I am not around. (There once was a rumor of a Mac that caught fire!) I expect that my power supply could go at any time, but I haven't had to shell out $200 yet. >of turning the computer off? The serviceman says to get the "Pyro" >screen saver program. Does that actually give the board a chance >to cool down, or is it no different than turning down the brightness? Screen savers amount to about the same thing as turning down the brightness. Doesn't help the analog board, helps the tube from gettng burnt. Kent Borg kent@lloyd.uucp or ...!husc6!lloyd!kent
