Microsoft is finally rolling out an overdue update for the Surface 2 Pro tablet PCs after an earlier update in December left users with reduced battery life and unexpected glitches in the tablet's sleep mode function.

Microsoft's blunder with a previous update for Surface Pro 2 left users unhappy. The Redmond software giant rolled out an update last month, which was meant to improve the battery life of the Surface Pro 2, but unfortunately it did exactly the opposite. Following several users' complaints about the update, Microsoft pulled it down and promised a fix "after the holidays."

Better late than never.  Microsoft is rolling out a new update to address the issues with the former update in Surface Pro 2 tablets.

The December 10 update ruined the overall tablet experience for Surface Pro 2 users. Several users complained about battery drainage, as well as error messages while charging. Some tablets also failed to detect a connected power supply, or even stopped before fully charging the tablet. Besides the reported battery problems following the sluggish update, Surface Pro 2 owners also complained about the tablet refusing to go in to sleep mode, or would turn off completely when the cover was closed, which is an alternate to sleep mode.

In a statement sent by Microsoft's public relations firm, Waggener Edstrom Communications, PC World reports: "This weekend we released an update that addresses the unexpected wake and battery drain behavior experienced by a small number of Surface Pro 2 customers who installed the December Windows Update. This should have no impact on customers who had not received the December update. We are working hard to deliver the rest of the December update to those customers who had not received it prior to it being removed from distribution."

In October, last year, Microsoft received complaints about the Windows RT 8.1 update from some Surface RT owners that the machines were freezing. Microsoft was forced to pull down the update  and  fixed the issue with a follow-up update.
