Hi Mac,
I have the same issue. One day in October I am using my surface pro and then a few hours later I come back and see it will not switch on! After dozens of calls, emails, cases made in October until now, I am no further. I have been told it's a hardware issue and Microsoft offer me the solution of buying a new one. My partner bought an Acer and I downloaded a reset picture and recovery point on a USB from a brand new windows 10. I then tried resetting the faulty surface pro laptop with this USB but it still does not turn on. The logo appears and disspears and that is all that happens. I only ever used the laptop for work purposes like email, Microsoft office. I don't understand how a flaw in their devices is the customers fault? Microsoft need to take the blame for their faulty products and give their customers ones that work. Like you, I thought buying top of the range laptop would save me this kind of hassle. Never again!!.can I ask did you ever get sorted?
