RE: RE: (ukha_d) UPS

["Nikola Kasic" <nikola@xxxxxxx>]

Peter,

UPS is usually connected to PC via serial (non-standard) cable. At least mine is (APC). It can then pass details about power to PC (about battery, logs etc.). There is a software, Powerchute, (which I don't use) which starts shutting down windows properly after configured period of time, to prevent crash when battery dries out.

I have Win2000, so I don't know about XP.

On my UPS, I have five leds which indicate how much UPS is loaded. I have 700VA UPS and connected server, network switch, ADSL modem, and possibly few more little devices. My UPS has 4 sockets and I connected power strip on one of them. Still it's showing that it's loaded less then 20%. I don't have monitor there.

I think that mine can last more than 15 min on batteries, and because I never had such a long outage, I never bothered installing PowerChute.

My UPS serves me as a voltage regulator as well, because it shows me that in 70% of the time it's cutting voltage because it's too high. Strange, because I'm in London, in a new building and I asumed that power supply should be stable and within the specs.

Hope this gives you some idea.

Nik

It is up to date, but that wouldn't make any difference - the UPS isn't very
clever - it's not connected to the PC in any way (other than power).

IME on XP, IRQ_NOT_LESS_THAN_EQUAL means a device driver has blown up.
That
could either be the UPS driver having a fit, or a driver for one of the
USB
devices getting upset when the USB devices power off. Best way to find
out is
to unplug everything and test powering off.

Could this be a conflict of IRQ's? Not an XP expert but it sounds
like
something wrong along those lines. Perhaps the UPS is trying to fire
off
an
IRQ events to tell the system that the powers gone, but it
conflicting
with
something?

Just a stab in the dark (excuse the pun).
