Crap. My Surface Pro also died after a year plus.
Out of warranty and I just cannot switch it on.
I brought it to a shop who think it's the hard disk and offered to fix it but if not the hard disk they then won't charge me. I used to love the device but I search and found some people had the same issue and I tried the different solutions they have and didn't work. A few of them also had concluded that the hard disk died. It's supposed to the SSD. Sigh. My love hate relationship continues.
