A quick google turns up rather conflicting data, as if the chip is using an internal or (up to) two external sensors (which sound like thermistors).

I can't think off hand why it would have some power draw, unless the whole thing is on standby (as opposed to really/truly off). Copiers (there really is the printing side of a copier in there) usually have a warm-up delay, but I don't think it would be that critical. >This is where I'm stuck.

I'd try running a packet sniffer on eth10 (/usr/sbin/tcpdump -i eth10 -n) and see what if any traffic exists. Another option is to try pinging the addresses in the range 192.0.0.1 - 192.0.0.254 (a broadcast ping of 192.0.0.255 probably would be ignored). Look in the arp cache (/sbin/arp -a) and see what shows up with a MAC address - possibly 00:60:B0, or 08:00:09 >> Your power never goes out? > >Maybe once every two or three years.

Your surge protector may or may not help. Big deal is the difference in voltages between "ground" and what-ever else is around. If the whole building suddenly jumped up to 1000 Volts above ground for a second, it's _probably_ going to be OK as long as the building entrance grounds are tied together. Problem occurs when the grounds are in physically different locations. Old guy

Went outside and timed stator of watthour meter with printer unplugged (1:23, 1:14, 1:16) and plugged in but switched off (1:49, 1:52, 1:56) -- that's a minute and some seconds for the stator to make one revolution.

What you are measuring is the forward voltage drop across the diode under a "known" current. That translates directly into temperature at that spot on the die (which probably isn't the hot spot on the die). See the Intel spec sheets for the CPU for details. The words you are looking for are "Thermal Diode". The problem is measuring that voltage accurately, and converting that digital value into an assumed die temperature. Old guy

But since I suspect that the transverse conductivity is at least as good as the vertical, I would suspect this temp is close to the mean of the die. If this thing is reporting temperatures out by 20C it is not worth anything. Intel CPUs report their temperatures far more accurately than that. My cpy even not running is at around 38C under low loads. I simply do not believe 27 unless you are pouring liquid N2 over the chip. > Old guy |
