Is Sleep the same as Standby ? (I'm running a desktop unit here.) If so,
go with Hibernate. It turns your computer off . (At lest I think so as the
power light goes off.)
Correct, "Hibernate" writes the current contents of RAM to a disk
file, and shuts the computer off. When you boot, the OS looks for a
hibernate file. If it finds one, it reads it and recovers the previous
session from that. If no hibernate file exists, a normal bootup
occurs.
"Sleep" mode powers down the disks, the monitor, whatever else power
can be removed from. The machine is not actually powered down, and
data continues to be stored in RAM, so it can be restarted more
quickly then if it had hibernated. But it uses more power in this mode
than if it hibernated.
I think that "Standby" and "sleep" are two words for the same thing in
Windows XP. The "Power options property" dialog allows you to
configure parameters for standby and hibernation.
