Most of us can't do it. We can do a guess by taking care of the computer
gears specifications, plus doing a very inaccurate, raw measurement
using an elCheapo power coasts meter. Note, the measurement accuracy
given by the specifications of those elCheapo power coasts meters are
completely wrong, those devices are far away of being that precise, they
are absolutely unusable even for raw consumption measurements, but they
might indicate, if there should be a computer device that does consume
much less or more than it should regarding to it's specifications.
