Hi, I'm new, be kind I bought a surface pro 2 in the US in October 2013, and all was fine until I started getting problems with the December update (not sleeping, reduced battery life, overheating). Having read the forums/news I appreciated that it wasn't just me and I should wait for the next update. Installed the Patch Tuesday Defender updates from the 14 Jan in the UK hoping that some things would be fixed. Apparently not. Now the battery life is non-existent. I had a fully charged SP2 this morning, my default is powersaving mode. Just turned it on at the other end of my long journey, and my SP2 is warm to the touch and battery indicator is 5%. Is there any other update I'm missing? Should I got to MS support? Will hibernate rather than sleep help? Just starting to regret my 'always keep up to date with updates' ethos now. Any help appreciated. Cheers.
