The myriad problems with Microsoft's Surface Book and its Surface Pro 4 tablet are well documented, and now we know what Redmond's definition of "quickly" is: A period of time no less than two months in length. The company has released a rash of updates to the devices that it says will help users get the most of the platform's power management options. There's a baker's dozen of them and the most common phrase among the listings is "improves system stability." That applies to everything from updates for audio drivers to the Surface Management Engine and a lot in between.
