Battery Meter for Laptop

[frankiebaby]

Anybody have any Idea on how to determine the voltage of the battery on a thinkpad 380? Or anything about the battery status, besides % remaining. Voltage, current whatever. Any ideas, even if just where to look would help thnx!

Does the computer itself show the battery voltage in some way? On screen? If so it is probably using a bios call and you'll need to do the same in your program.
