Sorry, I re-read and see that Vista came on it originally. I looked up one A200 model and Toshiba shows this link & info.

You can look around in your BIOS setup page and it will show the version you currently have. Check that against Toshiba's site. Since this model is a few years old, it wouldn't be uncommon for Toshiba to stop providing updates.
If you received a message that the BIOS update you were trying to install wasn't needed (already up to date), then there's nothing you can do. As long as you were downloading the latest available update. You chance bricking the computer by using non-standard or beta BIOS software.
ACPI - Advanced Configuration and Power Interface, is a standard for software and operating systems to work with your hardware. I'd venture a guess that the power management software is newer than the BIOS instructions in the computer. Just a theory.
You could try playing with the power management software in W7 or see if there's something you can turn off and see if it makes a difference. Does the computer shut down in Vista w/the battery & PS plugged in?
