The newest Surface line of devices has been marred by a few unsettling problems. They just didn't seem to enter into the deepest of sleep states, which means the battery would run down far faster than you'd expect. Sometimes even being dead when you really wanted to use them. Some new firmware updates have been pushed out by Microsoft that finally solve those long-standing power drain issues.
The CEO of Microsoft, Panos Panay himself, actually posted in a blog post to communicate how thankful they are of patience from those affected. "Today's updates include a set of Microsoft and Intel driver and firmware updates for Surface Book and Surface Pro 4 that will help you get the most of the power management options that Surface is designed to offer and continue to make your Surface more productive," Panay wrote in the post. "We love our Surface customers. You are our early adopters and our fans and you keep inspiring us with what you are able to do with Surface. You keep pushing us to make Surface even better."
Power management was one of the first issues noted by some of the early adopters, and this update is long in the making. It was one of the most requested updates despite it largely being ignored until now. Battery life could potentially be reduced to around 3-5 working hours, sometimes even being completely drained once arriving at some far off destination. It didn't quite work as advertised, and was incredibly frustrating. And this is just in time for our long-term gaming focused review of the Surface Book. How delightful.
