On Windows 7 a Vostro 3500 laptop shows the battery life remaining, while on Windows 8 this information appears to be missing. The percentage is still available, but the life remaining is missing.

How is battery life remaining calculated and does this require some level of driver support? Is it a standardized interface? Does anybody know which driver is responsible for handling this feature?

I want to force the old Windows 7 driver, but I don't know which driver does battery remaining.
