Microsoft issued the January 2016 firmware updates for the Surface Pro 4 and the Surface Book this week. As you may have noticed, the updates don’t provide a fix for the infamous improper sleep and battery drainage issues. But be rest assured, Microsoft is working on them.

The Redmond, Washington company has addressed users concerns on the Surface Support website to let them know that it is working on the aforementioned issues. “Yesterday our engineering team published some updates for Surface Book and Surface Pro 4. These updates offer refinements to improve battery charging and thermal tuning, wireless and Bluetooth performance, and to the detach-reattach experience on Surface Book,” the company wrote.

“We know some of you are still experiencing issues, including issues related to power management, and we are working to address those as quickly as possible. We’ll publish additional updates as soon as they are ready.”

Several users of the Surface Book and the Surface Pro 4, the two computing devices Microsoft launched in October last year, complained about improper sleep issue on their devices. The issue, as you can imagine, took a toll on the battery life as well. Microsoft last month acknowledged the issue but noted that the fix will only be made available in early 2016.

Media reports suggest that the issue is incurring from a flaw in the Intel Skylake processors lineup, and many non-Surface devices are impacted too.
