Solved Blinking Power Supply (How to Fix)

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?

So honestly I thought this solution was nuts, but I don't have the money to replace it or the time to wait for a replacement so what the heck... I tried it and for no good reason... it worked!! Thanks for the idea! Next paycheck I will order a new one, but for now.... keeping my fingers crossed!

Yes, but this unplug, replug only works once.
The charging worked for a while but then started flashing.
The "fix" did not work again

I experienced the same problem with a Surface Pro 4 that had sat on the shelf for months and unable to charge using the MS Surface Docking Station.

Problem: Connecting to a MS Surface Docking Station overnight. The power light blinks and the Surface does not charge.

Solution: Use the Travel power adapter. It's dumb enough to charge the nearly dead battery in the Surface. Once charged, then use the MS Surface Docking Station as usual.

Yep, the battery was dead flat. Using a travel charger brought it back to life. Thank you!
