Ok, everyone. (Few product issues are as infuriating as this because I want to love this device). After living with this issue on/off for a few months and trying/applying every update, patch, resetting
firmware settings I am 99% sure it is a heat-related
issue. Plugging the device in or on the dockstation it begins to recharge. After about 5-15mins of recharging it sometimes shuts down. The back of the surface closest to the display port and USB is exceptionally hot upon touch each time this happens (hotter
than during normal usage). I believe this is very clearly an overheating issue during charging and it may be why it has taken Microsoft so long to offer a fix.
As I have already said before, I'm quite sure that there are different issues involving the Surface Pro. The one discussed here refers to the Surface Pro randomly hibernating, i.e. you may be using Word, Excel or surfing the web, or doing nothing, and it
hibernates, sometimes after 3 hours, sometimes after 10 minutes. No problem with overheating, mine was never hot, not even warm, during use or while recharging it, but it hibernated. I imagined all possible scenarios, but the final result was that the issue
was totally random.
After I updated the Nvidia drivers and applied the patch that you can find at this address:

I never had the problem again. Never. It's now 3 months at least I'm using it, never happened again, before it happened 2-3 or more times per hour.
Therefore, either you have THIS issue and THAT is the solution or you have another issue and my suggestion is to ask for a replacement as soon as possible because I'm quite sure that you have a hardware issue that cannot be solved via software.
