I guess way back when, when my school was built, they had some sort of system that sent a small electrical pulse to every outlet on campus, this was used to trigger the auto set on all the clocks. now, most of the clocks have been updated and are on their own secure network... but this system still exsists. example: every hour on the hour, my touch lamp that i have turns on, starts dim, next hour gets brighter, brightest and then after that it turns off. my question, could this be bad for my computer and other electrical equipment that i have plugged in here (laptop, cell phone charger, klipsch 5.1's, extigy sound, fridge, tv, microwave, ect.) I thought that plugging things into a surge protector would work... but it dosen't, my lamp will still turn on if it is plugged into one. (a teacher i asked said somthing to how the surge was small enough that it would pass though the protection on a power strip, then he went on to talk about a line conditioner) anyway... what do you guys think?

I would be worried cuase there are still power surdges getting through you power bar which could damage your computer. Try a really high quality power bar, perhaps that would work better, I really dont know mabey an electrician would know what to do.

I can tell you that there are 2 kinds of ups that I know about. The kind with and the without line conditioning.
Without Line conditioning make sure it cuts to battery when the voltages get out of whack. For example mine will do that. So if I have a surge, blackout, or brownout it will kick to battery. So for example when my laser printer powers up it'll draw enough voltage to kick the ups's battery on.
With a line conditioner in the same situation it wouldn't just kick on the battery it would add or decrease the voltage so it always stayed at the proper level.

Considering this happens once an hour you may want to spend the extra money for a line conditioning ups as having the ups kick to battery once an hour could possibly kill the ups's battery rather quick.

Here's an assumption:

Those old clocks probably used a low voltage, high frequency pulse to keep everything synchronized. All the clocks needed was a bandpass filter to only allow a certain frequency spectrum in to catch the pulse.

This is very much like how power plants use their own power lines to transmit information from one power plant to anohther.

If this is the case, your computer's power supply creates DC current using a bridge and some filtering/capacitors. In all likelyhood, this pulse would be filtered by the time power leaves the power supply.

if you don't notice all the lights in the room getting bright ofr a second, iwouldn't worrythat much.

I used to use them too but awhile back my friends hourse got struck by lightning and there was nothing left in his house that worked. He lost 2 computer, 7 cordless phones, home theather system, 40" tv, vcr, dvd and numerous other stuff. I went out and bought this from futureshop

*edit, oops doesnt automatically make my link linkable

Get a UPS or line conditioner that will compensate peaks and drops (and line noise)

never ever buy belkin power products. or anything else. except for maybe cat 5.

neither of those are inline. there was a big thread over in GH about UPSs a bit back, lemme see if i can dig it up

That is right. I would never subject any of my electronics to a Belkin power protection (yea right) product. I've seen more Belkin's fail than all other brands combined.

I recommend Opti or APC. I use both and they work great.

I agree with that. APC makes excellent power protection products (especially their older ones). The one Viewsonic Opti-UPS I worked with seemed to work pretty well.

Why would you put a laser printer on your UPS? :confused:
