Staples has them back in stock and at $60.00 it seems to be a good deal. Has AVR which is something I am looking for as my laser printer draws tons of power when it warms up.

The AVR is good, no doubt about it.
My Energizer UPS says:
"DO NOT use your UPS for: laser printers, vacuums, space heaters, copiers, or shredders.
Thanks. Now I understand. I just plugged my laser printer into a surge protector on a different outlet from the computer.Originally posted by: silverbullet555
I don't have the laser printer going through the UPS. But, the laser printer plugs into an outlet that is on the same circuit so when it powers up it consumes quite a bit of power for a few seconds. This has caused my computer to restart as my current UPS does not have AVR.
You're right. It was old stock, and TD knew it. That's why they lowered the price to dump them. It was our good fortune that the UPS company set the thing right.Originally posted by: Elixer
If the UPS unit is bad, then how is it that (in this case) TD sucks?
Thanks for that info.Oh, for laser printers, you need 4x the size of a UPS, since when it first kicks on, it puts a HUGE surge on the system... I have seen 1500VA UPS units been taken out of commision by some laser printers!
For the record, *all* UPSes say that.. generally the high current-draw of those devices tends to overload the inverter used in UPSes. It doesn't have anything to do with AVR, I don't think. I've never seen a consumer-class UPS that didn't have that warning on it.Originally posted by: emeraldsky

The fact that those units were selling at TD for less than half of the price anywhere else, seems to indicate that perhaps they knew about some "issues" with the units, or that the batteries were probably shot, if the stock had been sitting in a warehouse that long or was exposed to extreme shock/temperatures. They were definately "priced to move", not "at current market prices". I can't prove anything, but it seems likely. Grocery stores often do that. Most people never notice nor care, although sometimes I notice when stocks of something are marked way down to move them, and it doesn't correspond to any mfg-related promotions.Originally posted by: Elixer

Yep. I've also been seeing a disturbing trend, I've seen three APC UPS so far, that their inverter overload-detection circuit has somehow degraded, such that they randomly start alarming (overload alarm - different than battery-low alarm, and more annoying-sounding), within about a 1.5yr timeframe from when they are purchased, and it has nothing to do with the battery's state or capacity. In all cases, the load being drawn is no-where near the inverter's limit. (In some cases, the load connected had been switched totally off, which clearly indicates the UPS has gone defective.) In another case, it was a 650VA unit, and the only things left powered-on were a DSL modem and a wireless router, which shouldn't take much current at all. IMHO, APC must be having some QC issues these last few years. (Note that this observation is for three out of three APC UPSes that I've been around the last few years - IOW, all of them have eventually prematurely failed this way, in different physical locations, in different applications. The only commonality here is that they were APC UPSes.)Originally posted by: Elixer

Even without AVR, that shouldn't be happening. You either have:
1) low AC current on that circuit in the building, solution = plug in laser printer into a different circuit. Just make absolutely certain that both circuits are wired up the right way around.
2) noise from switching on the laser printer enters the computer's PSU and causes problems, solution = get a surge-protector with EMI/RFI filtering. However a UPS should provide that automatically. Could be a cheapo PC PSU too, perhaps replacing that would help.
3) a defective UPS, it should switch-over (entirely) to battery if the input AC voltage drops too low, my current Tripp-Lite does during brown-outs. AVR makes it more efficent though, because it allows the UPS's battery to last longer during brownouts, since it's only partially instead of fully running off of the battery.

I have had bad UPS units from BB & staples, but in both cases the UPS company in question fixed the issue.
