Hmm, wonder if it would work properly on Windows while in power saving
mode?  My thinking being that they may put something in their own driver
software to compensate for hardware flaws.  Rather than redesign their
hardware to remove the flaws.  It was a common enough practice, and I'm
sure it still goes on.

I'm always a bit suspicious of power saving modes.  Firstly whether they
save any significant amount of power to make it worth while, whether
it's worth saving power if you then have to wait for things to wake up,
and whether they will wake up.  I've seen things that just go into a
coma, or require resetting once woken up (and they don't get reset
automatically).
