So I have had problems with my surface pro 2 since day one. I bought it about 4 months ago, and the keyboard input was always laggy, touch input was way behind and it was just generally slow. I had my computer buddy check it out and it turned out I was having hard disk problems, Event ID 153 about 5 to 10 a minute. Anyways Surface Support said they would warranty replace the Surface. I took it to the MS store in SLC and the lady swapped it out for me. Upon completion of this she was trying to wipe the Surface. Lady: "There were some problems and it says some files are missing so I will work on it in the back later." Me: "I know there are, I put the recovery partition on a flash drive." Lade: "What? That voids the warranty! Well since the transaction is already complete I will deal with it, but next time don't do that!" Me: "Seriously? It's part of the OS how can that void my warranty?" Lady: "It just does, next time make sure you put it back on if you bring it in." Me: "Uhh ... OK!" Is this true? Does putting the recovery partition on removable media void the warranty? It's part of the OS so I don't understand how it would and I read bits and pieces of the warranty manual and it didn't say anything about it. What are you guys thoughts? Thanks!
