    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.

    I can confirm both of of dnieby's experiences. I too was charging my phone from my Surface 4's USB port before this happened. I could do nothing to stop the blinking. However when I unplugged the power supply from the Surface (kept the power supply plugged into the wall) plugged my Android phone into the power supply's USB port and, finally, plugged the power supply into the Surface again, the blinking immediately stopped.

    Additional note: I had allowed my phone to charge to 100% via the Surface USB before the blinking began. Not sure if that had anything to do with it, but maybe it confused the "smart" power supply?
