That is a cost of doing business. I remember big signs at Digital,
Spitbrook to turn off computers at night. I rarely saw anyone do that
except for some laptops. We come from the 24x7 era. I generally shut
down my work laptop and workstation on weekends, partially because the
heat and cooling stops on weekends here.

On a related note, in general laptop power supplies pull power whehever
they are plugged in regardless of whether they are charging their laptop
or cell phone. Motorola is now selling a green charger that only pulls
power when the attached device is charging. I have not see it much

Most of the energy used during the use phase of a mobile phone=92s
lifecycle is wasted when the charger is left on standby (plugged in, but
not in use). Since 2000, Motorola has reduced the average standby power
of its chargers by 70 percent, and the new EcoMoto=99 wall charger
consumes just 0.03 watts on standby, 90 percent better than the current
Environmental Protection Agency ENERGY STAR standard.


I still have my abacus. Maybe I'll bring that into a restaurant to
compute the tip rather than my Android :-)
