Hi, when one has a NeXT running all day (e.g as a uucp-server) one doesen't want the Display on all day. Dimming it prevents the burn in on the screen, but the heating for the tube is still on and the monitor still consumes energy. Does someone has a solution for this e.g. with a add-on switch for the monitor or so ? Or is there a software-solution for that ? -Heiko -- Heiko W.Rupp, Gerwigstr.5, D-7500 Karlsruhe 1 | hwr@pilhuhn.ka.sub.org Tel: +49 7021 693642 (voice only) | uk85@dkauni2.bitnet What do you think of western civilisation ? - Should be introduced !

Or is there a software-solution for that ? I work at an Audio/Video store, and I spoke the the "Techies" there a few months ago about this very same problem. I was told quite simply that if I could make the screen turn black, I was fine. Leaving the monitor powered on is no big deal if the guns aren't on (black). This would be analagous to leaving an audio amplifier or preamplifier on 24hours per day, even when not listening. This is a practice followed by most "audiophiles." Also, power drain is minimal, so I was told not worry about it. If you are worried about, you are probably better off powering off your machine. -- MikeC _________________________________________________________ Michael D.

After using the NeXTStation Monochrome 400 for the first full month and receiving my electric power bill I can make the following non-authoritative statement about power consumption: I had the station on practically the whole month (it was off perhaps fro about 20 hours total). My Power bill has gone up by about $ 7 for the month (i.e., 52 kWh). This averages to a consumption of about 72 W which seems somewhat low. Given the fluctuation in consumtion by other appliances, one might assume that 100--150 W is a correct ballpark figure. It would still be nice if one could switch the monitor off, though, when away from the machine for more than, say, 4 hours. Greetings, Hardy -------****------- Meinhard E.

Or is there a software-solution for that ? This may not sound like an ideal solution, but I haven't seen any original suggestions for this problem in a while, so I'll bite. According to the documentation (Network and System Administration Manual), if the monitor (and therefore the keyboard) is not plugged in at boot time, the system will alternatively go to serial port 'A' to use it as a console. So presumably you could connect up an old terminal to the serial port and boot your machine after unplugging the monitor. I haven't actually tried this, so don't sue me if it doesn't work. -- Trevor Bourget (trevor@telesoft.com or uunet!ucsd.edu!telesoft!trevor) p.s. Come to think of it, this might be a way for those NeXTstation color wannabees to buy their slab and sort of use it for a while until they can get the cash to get a color monitor (no, Virginia, you can't use the monochrome monitor; it's not the same cable). It's not NeXTStep, but at least it's UNIX.

NOTE: On older cubes (probably around the first four thousand), the power supply will not operate if the monitor is not plugged in. The older power supply requires a minimum amount of operating load to be present. :-) Joe jchin@van-bc.wimsey.bc.ca -- ************************************************************** * "Kill the body and the head will die" (Hunter S.
