[G4] Sleep, Different Kinds

[Brian Silverio]

Anne,
"Use separate time to put display to sleep" just turns your monitor 
off.  If you are running a download or or backup they will continue to 
run.  Move the mouse or press a key and the monitor turns back on.

"Put the hard disk to sleep when possible" will cause your hard 
drive(s) to spin down if they are not accessed in some (unknown to me) 
time period.  I have five drives and find that my boot drive rarely 
spins down.  The others often do.  Then when I do something that uses 
the "sleeping" drive I have to wait for it to spin up to speed.  Again 
downloads and backups will continue to run w/o problem.

"Put computer to sleep when it is inactive for x minutes" is another 
story.  My understanding of "inactive" is that a human has not touched 
a key or moved the mouse in x minutes.  when this happens your 
downloads will stop, also any other process that is running will stop.  
Things will resume when you wake the machine up.  Your download will 
have to be restarted.  I would think twice about trusting a backup that 
had a system sleep happen in the middle.  Unless you had verified the 
backup.

I hope this helps

Brian
