I, too, am a firm beliver in leaving my PC's on. The ones at work we leave on constantly. We have a couple we've had for over three years and they're working as good as our newer ones. For my personal XT at home, I leave it on constantly except for during thunderstorms or when I know I'll be gone or not using it for a few days. The thing I've always wondered about is monitors. I turned mine off when they won't be used for a few hours. I've looked at screen saver programs, BUT: Most screen saver programs save the screen contents in memory and then display a blank screen. So, the CRT is still powered up and all the sweep circuit is still going. Therefore, my question is: IS it better for the CRT to be left on constantly (as far as the cathode and analog sweep circuitry) or to be turned on and off once a day? -- John H.

I can't speak about an AT monitor in particular, but here in the UW CS dept, we leave the monitors on for all terminals and workstations 24 hours a day, all year long. In the case of the B/W uvaxII monitors, cycling the power is really hard on their circuits. We recently moved to our new building and lost three or four monitors because we had to turn them off and on. My monitor now has problems but is still usable (it's been replaced once already). I also leave the monitor on my home terminal on all the time (I do turn down the brightness when I'm not using it); cycling the power on it also makes the screen do strange things until it is fully warmed up.
