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.
My Dell Mini 9 seems to run out of battery power very quick but I don't get any error messages.
It would last quite a bit longer with XP.
The issues seem to be very drastic i.e. 2.5 hours dropping to

...nothing?
HP mini 210 lasts about 9 hours running Windows 7 Home Premium. It's got an ugly battery sticking out of the back, but I can't complain about the battery life at all.
@toast I think his batter died. ;)
The more I use it the shorter the battery seems to last. I'm averaging an hour. This is just Facebook browsing mind you. No YouTube or videogames.
I can't even play Magic the Gathering Online because of the screen resolution! XD
Sony Vaio FW :- I thought it was just me who was having this problem or do I really need to change my battery?
My Dell XPS m1530 laptop battery life dropped from 3 hours to less than 30 minutes on a full charge over 3 months
