Microsoft says it's looking into laptop battery issues with Windows 7

We've already seen some evidence that suggests Windows 7 puts a particularly hard drain on at least some laptop and netbook batteries, and it looks like Microsoft has now heard enough complaints itself to open an investigation into the matter. Details are otherwise a bit light, but Microsoft is apparently looking into the issue in collaboration with its hardware partners, and says that the problem is likely related to the computers' BIOS, which Windows 7 relies on to determine if the battery needs to be replaced. Needless to say, there isn't much in the way of solutions in the meantime, and Microsoft isn't offering any indication as to when one might be forthcoming.
