Microsoft released a software fix for its Surface Pro 2 this past weekend notes ZDNet, addressing power management problems for the device. The cause of the problem was a December firmware update for the device that didn’t install properly for some users. Those that did get the December update installed experienced various issues such as rapid battery drain, not charging while plugged in and sleep / wake issues.
Microsoft(s msft) pulled the December firmware after Surface Pro 2 users complained about the issues. The company then said it would have a fix after the holidays. ZDNet’s Mary Jo Foley received an official statement from Microsoft on the firmware fix:
“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.”
The December update for my Surface Pro 2 actually failed, so I don’t expect to see this fix and therefore can’t report on if it addresses the problems caused by the last update.
At least one user in the Microsoft Surface Pro 2 support forums has received and installed the update, which appears to be rolling out in a staggered fashion, and reports success: “So far, my 128gb Surface is now back to normal. It sleeps properly, does not wake up on its own, and goes into hibernate as it should. I think, at least on the issues I had, the problems are resolved.”
