Thread: Need program to play WAV depending on laptop power status

As title really..

I need a program/script that will play a WAV (a different one each time) when:

a) Laptop battery is fully charged
b) Laptop battery is low (say 30%)
c) Laptop battery is critical (10%?)
d) Laptop switches to AC power
e) Laptop switches to battery power

Can't seem to find any generic programs that can manage this, nor can I seem to find a way to do it in vbscript. (Although MSDN seems to think you should be able to).

Any ideas people?!
