Stop user from canceling hibernation

I have my machine set to wa me when the battery is at 25% and got to hybrid sleep at 15%.

Well, I must have been extremely focussed on what I was working on because I didn't see the waing bubbles and suddenly lost power and some amount of work.

Is there a way to force the system to go to hibeation/sleep regardless what I am doing or wa me in such a way so I cannot miss it, a system dialog box perhaps?

Thanks.
