Sleeping when battery dies..

I know when a Macbook dies completely will it be in the same spot where you left off, but is their anyway I can make sure it is logged off/powered down when it is plugged back in? I don't want my mom to open her MacBook at work and see what I was looking at..?

Thanks!

I love this question..... the answer is don't look at whatever you're looking at and then you won't have to worry about it. ;D
