Surface Pro 4, Surface Book Get Firmware Updates; Users Complain They're Buggy

Microsoft has released its first firmware updates of the year for the Surface Book and the Surface Pro 4 computing devices. The updates aim to deliver a range of improvements, though if you were hoping fixes for battery drain and wake-up issues, your wait isn't over just yet.

The Redmond giant on Thursday released January 2016 firmware updates for both its new Surface devices. The company notes that the updates will offer thermal tuning, wireless access point compatibility, and better support for 5GHz Wi-Fi network.

Additional improvements include enhanced keyboard detection and stability patches for Nvidia graphics cards. The description of the update confirms that Microsoft hasn't yet patched the battery drain and sleeping issues in the Surface Pro 4 and the Surface Book, and that should upset many users.

Last month, Microsoft acknowledged an issue with the Surface Pro 4 and the Surface Book that was preventing the devices from going to standby mode properly - this as you can imagine, also took a toll on the battery.

This is apparently happening because of issues in the Intel Skylake chipsets. Microsoft last month noted that it would release a fix for the aforementioned issues "sometime soon in the new year." Now, it appears affected users would have to wait for a few more weeks.

If that wasn't disappointing enough, the updates as per user complaints and are also causing driver issues. Oddly enough, the update has also made it harder to detach the Surface Book screen at all. Some users also note that after the update, their Surface device has stopped recognising the Surface Pen.
