    I saw this come up a. few times around the web so I figured it'd be a good thing to post this for people's reference.

    First, if it's blinking, there IS an error. Contact support and they will send you a new one. It was quick and easy to get done and they're very helpful.

    HOWEVER, if you can't wait for a new supply, you MIGHT be able to get yours running again like I did.

    To set up things I have to note that before it started, I did have my phone charging via Surface USB Port. I tried everything I could think of to cause the power supply to "reset" and
    nothing would work. I also have the issue where the supply cord is pulling away
    from the magnetic connector. (IMHO, the ONLY poorly designed part of the power
    supply.) First, I unplugged it from all sources and left it unplugged for a bit. That
    didn't seem to do anything. ODDLY enough, something DID work. I plugged my
    PHONE into the USB supply in the Power Block, THEN plugged my Surface Pro 3...It
    blinked, then reset. Now it is charging and I have a solid light.

    I don't know if it will last, but it does appear that the power block isn't
    just a regular power block. I think it's a smart block and it noticed there was
    some type of problem and shut down.

    Either way, a new one is on the way and I did appear to get this one working in the meantime. I hope this helps someone else.
