Thanks!
Did you mean to send this just to me?
I think others on the list would be interested...

That is true of almost all computers; desktops tend to draw around
15W when "off". That's because various components on the motherboard
are kept alive (frequently, for example, the LAN port - some even
have the LAN LED on when "off") and the start-up circuits have to be
energise to allow the momentary-action push-button to turn the PC on.
That's what the EU directive ErP/EuP is about: reducing what is the
hardware (not software) standby power consumption. In ErP/EuP 1, it
was specified as 1W, in ErP/EuP 2, 0.5W. But in order to achieve
this, both the motherboard (and any expansion cards, presumably) and
the power supply must be ErP/EuP compliant, and ErP/EuP features must
be enabled in BIOS. This will disable features such as WOL or wake on
alarm.

I don't know who is saying desktop pc's are pulling 12W but I
haven't seen a system that will pull that from the wall outside a
laptop.

In the last few days, I've been reading studies showing that
average power consumption of a PC is about 12W. Which
is not incredibly high.
Makes me wonder how much
I’m
killing the planet with the 700W power
supply in my PC.
Anecdotally (no calibration of the Meter):
My AL511 Acer Monitor is pulling 7watt on standby and 22-24W in use.
Router/USB 3G Dongle isn't registering.
The Laptop running with battery, external keyboard and mouse,Â
plugged into
power supply is pulling 14-19W.
It is worth noting, that to maximise battery operation, a lot of
research and
development has gone into developing energy efficient laptops.
I also buy the maximum RAM available, when I purchase any computer.
Removing the Battery and running off mains power, the Netbook is
drawing 17W, it spiked to 24W when the fan came on but returned
to 17W (with fan still on, while I wrote this email).
The power use rose to 19 W, with a spike to 24W, when I fired up
firefox.
When I opened up Open Office, it spiked to 24W then dropped back to
17,
then back to 19W.
Firing up GIMP it goes spiked at 22W.
Opening a document in the PDF viewer - the energy use spiked to
26W, before
dropping back to 17W
Loading ramin.com.au the power use is fluctuatint between 17-19W, for
slug.org.au 17-22W.
nsw.gov.au 19-24W
Writing this email, with Firefox, GIMP, PDF viewer and Open office
running
in background,
fan came on and electricity use is fluctuating between 17-19W.

cuiously, when the laptop is shutdown, it still draws 7W!
