If that's the right name.

At present, if the battery runs down when I'm not looking, on restarting
the machine (by pressing the power button) after connecting the supply,
it does a restart similar to if I'd shut it down, other than that it
gives the "Windows did not shut down properly", and some app.s say
_they_ did not shut down properly.

Is it possible to set something so that the system does a "sleep",
"hibernate", or whatever, so that when I apply power and restart, it
wakes itself up how it was? If it is, what settings do I have to change
where?

I'm not talking about shutdowns instigated by an action, such as closing
the lid or pressing the power button. Is it even _possible_ to trap the
"battery is too low" situation?

W7 HP SP1 32-bit.

The home software that comes with APC UPS hardware does precisely that.
When a time limit (user settable) is reached during a power outage, an
hibernate is instituted.

The only problem I've noticed with this occurs when you have a very
large memory: For example, I have 64GB of memory and that takes quite
awhile to save even though my C disk is an SSD. This causes software to
time out and initiate a "panic" shutdown. Further, Windows and most OS
demand to save hibernation on your boot disk - this is left over from
the BIOS standard that's been around for years. So the hibernation file
eats a lot of boot disk space. As SSD prices drop and sizes increase,
this hit doesn't seem so bad.
