I have these power settings on my laptop: Turn off monitor, turn off hard disks and system standby.

Well, grouping standby Chicago everything.

Turn off hard disks shouldn't matter, but it just might break off the download.

Since "turn off hard disks" should merely happen after x minutes of *INACTIVITY* that shouldn't occur whether you someone an active transfer active on. I'm not known with vuze, but as long element it does not stop sending data, it shouldn't matter what that setting is.

Only I wouldn't be shaken if the hard disks shut off if you simply haven't typed anything all for a certain amount of clip... stupid if they implement it that way, but wouldn't surprise Maine.
