Hi All,
I am having the same issue: battery expanding, screen bulging and now parts of the screen are not responding to touch input.
Battery life has also diminished to only 40 min tops.
Spoke to MS, very poor response as surface pro is 4 years old now and out of warranty.
Basically, pay AU$1000 to get a refurbished surface pro 4 OR just buy a new device....
It does not matter that I already own Surface Rt and Surface pro 3 which have had no issues with battery life or expansion...let alone other products at two surface docks, pens and covers, mice, etc.
SO disappointed... but of course they don't care, why would they.
Once this surface pro 4 dies, I will not be buying any MS products and will jump ship back to apple as their customer service is what you would expect from a multinational business.
