Yeah, your measurements are the best we got. But if you compare them to other people's readings, you take their errors on board.
Actually the main reason I did the Win7 power measurements was to be able to directly compare them to Linux power measurements on my setup, so to avoid comparing my Linux measurements with other peoples Win7 measurements.
Ultimately what I'm interested in is getting the same power draw with Linux as with Win7 (in the same circumstances).
I'm no expert either but I suppose it would be best if you could measure another board whose power consumption is known. But a 12VDC 10W incandescent light-bulb should be better than nothing. If your reading is way off, you'll know I was wrong.
I actually think (but if any electronics expert is reading this please correct me if I'm wrong) that incandescent light bulbs with a known rating make very good known loads due to their stable power draw and the PF of 1. I don't have a 12V light bulb here right now but I should be able to get one in the next few days.
Just to make things clear:
During testing , Lan cable was unplugged (I have only wifi network).
My powermeter is FHT-9999 , http://www.made-in-china.com/showroom/a ... 9999-.html
Power brick was Starmen TCS050120
Current was 230V AC
Rest was, as stated in the first post.
Keyboard and mouse were plugged in and VGA ELO touchscreen (touchscreen was off) monitor (19 inch 1280 x 1024) was connected.
My intention was not to fool anybody or provide false results . Just wrote, what was on the powermeter's screen.
I had no intention to imply that you wanted to fool anybody, I only asked you for more details so that we could try to find the cause of the difference between your and my readings.
Thanks for the details, the fact that you had the Ethernet cable unplugged explains a lot since that reduces power draw by approx. 1.5W in my testings.
You say you use wireless, but I guess you did not have a wireless adapter connected to the DN2800MT during your power measurements?
Also did you have "OS ACPI C3 Report" and "PCIe ASPM Support" enabled in the BIOS?
Was you monitor in DPMS standby (triggered by Win7 after 10mins of idle) or was it still showing a picture when you had the 7W reading?
