Microsoft has issued a statement on reports that a new group of Surface Pro 3 owners are experiencing battery drain issues with the tablet, denying that the new problems were caused by a firmware update released on August 29.
People that own Surface Pro 3 units with batteries made by LGC have been reporting that they appear to be stuck at a specific power percentage and labeled as "Not Charging" when the tablet is plugged in. Some people believed the problems rose from the firmware update on August 29, which was ironically designed to fix battery draining problems with another set of Surface Pro 3 tablets.
We are aware of a battery issue that is affecting a limited number of Surface Pro 3 users. We can confirm that the issue affecting these customers was not caused by the software updates issued on August 29th. Our team is actively looking in to the issue to determine the cause and identify a fix. We will post an update as soon as we have more information to share.
We will, of course, keep you up to date on this latest Surface Pro 3 battery bug.
