Hi, I have a Surface Pro (yes I know this is the SP3 forum, hear me out). I am thinking about buying a new dock off of Ebay, someone's selling it because it shipped without a power cord. I'd like to buy a power cord for it, but the only ones that are being sold on Ebay are SP3 Docking Station power cords. SO, I'd like to know if anyone knows if the SP3 dock cord will work with a SP dock. -- Thanks in advance! jackson1442.
