Microsoft is disputing Internet reports that claim its new Windows 7 operating system drains laptop batteries at an unusually fast rate or, at times, falsely warns users that their battery is about to fail.

"At this time we have no reason to believe there is any issue related to Windows 7 in this context," said Windows group president Steven Sinofsky, in a blog post Tuesday.

"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," said Sinofsky.

"In every case we have been able to identify the battery being reported on was in fact in need of recommended replacement," said Sinofsky.

His comments counter numerous user reports on Microsoft's support forum and tech blogs that suggests Windows 7 causes batteries to fail prematurely or issues bogus replacement warnings.
