A while back I bought a power consumption meter, which I can use to measure the power consumption of any electric device. This was a real eye-opener for me. I knew things used a bit of power while in stand-by mode, but I had no idea how much they actually used!
My computer + screen turned out to use a good 20W together, even when I had switched them off with (what I thought was) the
hard power switch on the back. In
soft power-off it uses 30W. Also, I found out that my speakers use 4W whether off or on, because of the power adapter.
Mum’s computer, which is a PIII 533MHz, uses a whopping 65W in normal (
soft) power-off mode! So, when you’re switching your computer off – pull the plug at the same time. That way we can take some stress off the earth.
