uhm .. just to be clear about terminology:
are you talking about "suspend-to-ram" or "suspend-to-disk"? Concerning the
former, it will take only days at best until your notebook batteries are
completely empty, and even this presumes their power level is fairly high
when suspending to ram and pulling the plug. At least in my experience..
If you meant "hibernation" as in suspend-to-disk this means roughly that your
working memory gets written to disk. Upon resuming the BIOS reads from a
special hibernation partition or a hibernation file, writes its contents back
to the memory and returns control back to the operating system. There's no
way that "hibernate dies" unless you use a hammer to awaken your lappy or
Magneto from X-Men is mad about you - because the memory contents are
physically manifested on your harddisk. This method's advantage is _exactly_
its independence from having power available or not.
Sorry if this is too OT by now. ;)
