Sinofsky: Don’t blame Windows 7 for battery problems

Microsoft Windows President Steven Sinofsky fired back with both barrels today at complaints that Windows 7 was to blame for degraded battery life on some laptops.

In a post on the Engineering Windows 7 blog today, Sinofsky said Microsoft did testing, analysis and review with PC manufacturers before concluding that the complaints arose because Windows 7 is showing more information about battery life than people are used to on their PC and some of those batteries are “in a degraded state.”

He wrote:

“To the very best of the collective ecosystem knowledge, Windows 7 is correctly warning 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. In every case we have been able to identify the battery being reported on was in fact in need of recommended replacement.”

It sounds like the sort of thing that happens with new medical diagnostic equipment or environmental testing technology, when a new tool starts finding unpleasant things. More from Sinofsky’s entry:

“The transparency provided in this new Windows 7 feature produced a notice that previously was not available to customers and did so shortly after upgrade. This is the root cause of the urgency with which we’ve seen postings, but does not change the reality of the condition of the battery. “
