Wow!!! Lot’s of “update” news this week. But, maybe, Microsoft finally got the infamous (and long-standing) Surface sleep issues fixed on the Surface Pro 4 and Surface Book.
Only about a week after Microsoft released a cumulative update (that was resetting the default file associations for some people), they dropped another update yesterday – which seems to include fixes for the the battery drain while sleeping problem that has plagued the SP4 and Surface Book since release.
The February Update for the Surface Pro 4 and Surface Book includes a whole slew of fixes and driver updates.

Surface Sleep Issues Fixed: Should I Install It?
If you’ve been plagued by the battery drain while sleeping issues you might want to give it a shot (you may need to go into Windows Update and tap the Check for Updates button).
I would advise you to make sure you have good backups and a USB Recovery Drive just in case. If you’re cautious or you haven’t had the battery problems, you might want to hold off and let the early adopters find the issues for you 🙂
While the folks over at Reddit seem to confirm that the battery drain issue is fixed, some people have already reported problems with the patch on the WindowsCentral Forum. It’s not clear how widespread those problems are yet.
