When buzz started being generated throughout online communities that Windows 7 may be causing premature battery degradation(causing batteries to die quicker than they should), Microsoft took the bull by the horns and began investigating. A spokesman from Microsoft stated at the time that it could possibly be a problem in communication between the BIOS and Windows as that is where 7 gets all of its data on battery life. However, that apparently wasn’t the case. In an official statement, Microsoft has declared that Windows 7 is not responsible for causing the alleged rapid degradation of notebook batteries.
“Windows 7 is correctly warning about batteries that are in fact failing and Windows 7 is neither incorrectly reporting on battery status nor in any way whatsoever causing batteries to reach this state,” Microsoft president Steven Sinofsky wrote in the Engineering Windows 7 Blog. “We are seeing nothing more than the normal course of battery degradation over time … In every case we have been able to identify the battery being reported on was in fact in need of recommended replacement.”
Sinofsky also stated- “It should stand to reason that some customers would be surprised to see this warning after upgrading a PC that was previously operating fine. Essentially the battery was degrading but it was not evident to the customer until Windows 7 made this information available.”
In short, if the “consider replacing the battery” notification pops up on your notebook shortly after installing Windows 7, the problem lies within the battery and now Windows 7.
