Microsoft has released yet another firmware update for its Surface Pro 3 tablet. It's the second such update for the product in less than two weeks.

Surface Pro 3

The last firmware update for the Surface Pro 3 was rolled out on July 22 to fix, among other things, a couple of minor battery issues. However, many owners of the tablet have been reporting for weeks that there is an excessive amount of battery drain from their Surface Pro 3 models. Microsoft later said it discovered the issue was indeed affecting a small number of customers and that it believed it was "something that can be addressed via software."

So far, there's no word on what's contained in this latest firmware release, but we will update this post when we learn more.

Update: Microsoft has now updated the Surface history page for the Surface Pro 3 with the change log to this week's new firmware update. Again, based on this information, this does not appear to fix the battery draining issues.

  • Surface Pro UEFI - v3.11.1550.0 improves stability and performance when changing between power states.
  • Surface Pen Settings - v12.0.303.1 improves system stability with the Windows 10 Anniversary Update.
