Notes: most appliances seem to consume about 4 watts on standby. Power adapters that are plugged in but not connected to anything still draw about 2 W. The X60 provides a very good performance to power consumption ratio! The ZX6000 workstation doesn't!

Preconceptions: I thought the audio amp and subwoofer would use much more electricity. Clearly, they use more the louder the sound output but the average consumption will remain low.
