Electrical Question re: computer

[Larry_OHF]

When I rebooted the PC today, the battery-backup on the floor registered a beep that power had been cut off from the main supply and that I was now on battery power...but this only lasted the length of one beep. It was not isolated to the PC as the phone which is sharing this USP also registered a break in current for the duration of a second. The power disruption did not affect anything outside of this USP, for the overhead light did not blink. Can a PC power-surge backfeed into the USP to disrupt electrical flow? In other words, can Windows cause such an occurance by merely rebooting, which involves only program-related activity and has nothing to do with the power supply in the PC hiccuping?

Sorry I don't know the answer to your question, but what kind of batteries are you using?? I'm having quite frequesnt power cut-offs which last just a few milliseconds but are enough to switch off the PC.

Just because you didn't notice the light blinking doesn't mean you didn't have a power break.

It takes more than a few milliseconds for the bulb to cool.

But at the exact moment of the reboot? That was just too close to be coincidental with no apparent provocation from any other external or internal source.

BTW, ZFR, its a Cyberpower UPS.

Larry I've used several commercial UPS's and my questions would be: How old is it? And when was the last time it was serviced? In my experience a problem like this is almost always a fault with the UPS itself. Usually it's battery. They are great when they're working, but seem to have a lifespan much shorter than your average PC. I have run a DOS only 1 program installed system with my AMEK RECALL Audio console off UPS for 5 years. So far: Failure> UPS:3, PC DOS:0

The UPS is about four years old I think. I did not know they had to be serviced...They can be serviced? I'd just buy a new one if this konks out. I gave about $60 for it.

Not worth getting serviced even if it could be. Bigger ones can. I guess they've priced it in the "just buy a new one" range...
