	The computer had been drawing at most 42W/.35A . I turned on
a 40W light bulb when the computer was halted, but not powered down.
(Its unable to power down by itself). So effectively when I
turned the lamp on, I was sucking MORE than previously since I
had a 40W bulb and whatever the "at rest" draw of the computer
was. (Not much, I realize, but still something)

	Unfortunately, since my monitoring host is also the
host it shuts down, this is the only logs I have :

20060512 080639 100 NA 0 [OL CHRG] NA NA

	I guess I wasn't defining the scenerio correctly.

	1) Power goes out
	2) UPS on Battery
	3) UPS gets to 30% battery
	4) System realizes it, does a "shutdown -h now"
	5) UPS gets to 1% battery 
	6) Power comes back on

	During the entire time, there was never a power loss to the
system

	Doesn't apply here, power was never technically lost, the
system only did a shutdown because it believed there wasn't enough
power left in the UPS.

	So why isn't UPSLOG not atleast showing the "ups.load"?


	I also now have a NEW issue

4) When the UPS was put back onto power, and I manually restarted
the computer, the UPS was charging :

20060512 100203 4 NA 0 [OL CHRG LB] NA NA
20060512 100703 6 NA 0 [OL CHRG LB] NA NA
20060512 101203 9 NA 0 [OL CHRG LB] NA NA
20060512 101703 11 NA 0 [OL CHRG LB] NA NA
20060512 102203 13 NA 0 [OL CHRG LB] NA NA

	and then all of a sudden :

May 12 10:26:27 soekris upsd[498]: Client upsmon at 127.0.0.1 set FSD on UPS [ellip
se]
May 12 10:26:27 soekris upsmon[519]: UPS ellipse at localhost on battery
May 12 10:26:27 soekris upsmon[519]: Executing automatic power-fail shutdown
May 12 10:26:27 soekris kernel: May 12 10:26:27 soekris upsmon[519]: Executing a
utomatic power-fail shutdown
May 12 10:26:27 soekris upsmon[519]: Auto logout and shutdown proceeding

	And it shut it down! It wasn't on battery, I know it.
