LOD continues while the 630 is powered down, as does the 830 (providing you haven't disabled LOD completely).
There is about a 1W difference as to when the fan is running versus not, but not standby versus "powered on", based on (previous) Energy Star and (more current) CEEVA testing.
I can confirm the HDMI port is completely disabled once the unit is put into standby.
