Windows Vista Power plans (auto save before shutdown)

I have the MGE office protection System (model NOVA AVR 1250).

IT connects to the PC by USB cable and Vista recognizes it (with out having to install any drivers)

and i set vista to shut down when when the UPS reaches 50% battery.

my 1st concern is it looks like Vista Powers off with out actually saving settings and shutting down, when restarting everything seems normal PC boots normally with out any errors, but i loose any Windows changes made during the last session, i haven't tried having open documents to see if i loose any Data.

after searching help and support, the MS Vista Site and google i still didn't find any answer to my problem so i figured i try using the scheduled Tasks to do that, but i cant seem to find the proper trigger.

im wondering if its possible to use "low battery level" state/ notification as a trigger?.

alternative methods are more than welcome.

 

Steve R Jones, very close I was also hoping it would also call the power company and complain about the power failure , but seriously I was thinking of making use of something similar to Alt + F4. which closes any open program (but requires a confirmation to save the item)

yes i thought about the saving everything b4 leaving My PC, but i saw no harm in seeing if there wasn't a fully automated Solution.
