There have been some reports of issues dogging Microsoft’s range of Surface products, from the Surface Pro’s issues with entering the “Sleep” state, short battery life, and the Surface Pen stylus playing up, and it now looks like Microsoft is taking these problems seriously and working on solutions.

This commitment to fixing the issues comes from a number of posts on the Microsoft Answers forum, where users can ask the community, which includes Microsoft representatives, for help with any issues they have.
