It took me a long, long time to find some useful figures. I did find something in the end though, it's a spreadsheet from 'EU Energy Star', the one I have is a few years old but it covers systems up to four or five years ago so is ideal for refurbished systems like the Esprimo ones above. (That should be Q556 not Q557 by the way). The file name of the actual spreadsheet I have is:- eu_energy_star_computers_61_-_20180220.xlsx I think searching for that name should get you somewhere, but if not then drop me an E-Mail (valid address here) and I'll send you a copy. -- Chris Green ยท --- SoupGate-Win32 v1.05 * Origin: Agency HUB, Dunedin - New Zealand | Fido<>Usenet Gateway (3:770/3) .
