If while booting the power switch is in OFF position, turn off the fan,
too.

Hi Tom, Hi Prafulla,

while testing, i noticed i've forgot to turn off the fan in power down
mode which was introduced in commit a9f1a4893364dd.

Tom, can you pick this bugfix patch so it can make it into the 2012.10
release?

Thanks, Michael
