Microsoft has issued a new firmware update for the recently released Surface Pro. According to the update's release notes, the update contains a single fix related to system power reporting, but it's not clear if this is related to the hibernation issues that many Surface Pro owners have been encountering since launch.

Microsoft releases Surface Pro firmware update with power reliability fixes

Microsoft categorizes this as a reliability update with the following change:

  • Surface – Firmware –233.1763.257.0: Surface System Aggregator - 233.1763.257.0 revises system power reporting.

To recap, a number of users have complained of a bug that would cause the Surface Pro to abruptly go into a sleep state seemingly randomly. Earlier this week, Microsoft noted that it had identified the issue and was working on a fix that would be issued at some point via Windows Update. It's not entirely clear from the release notes whether this update is that fix, but it seems highly likely.
