Unplug That Computer!

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.

    What’s the exact name of the product? Searching on the clasohlson site (I don’t speak Swedish) or for “etech e300 power meter” reveals nothing…
