If the LED light on your Surface charger is blinking, flashing, off, or on (but your Surface still isn’t charging), here’s what to do:
Check cables and reset your power supply unit: Disconnect the charger from your Surface, unplug the power cable from the electrical outlet in the wall, and then disconnect any USB accessories.
Wait at least 10 seconds. This gives the charger time to reset.
After that, clean everything with a soft, dry, lint-free cloth, and check for any damage. (Be sure to replace damaged cables.) Plug the charger back into the electrical outlet and your Surface.
Plug it in the other way: Flip the charger 180 degrees, and check to see if the LED light comes on and if your Surface starts charging again.
Try a different power source: Plug the charger into another outlet, surge protector, or power strip.
If you are using a Surface Dock: If the Surface device battery is empty, first charge it using the power supply that came with the device for a few minutes before trying to charge with the Surface Dock again.
Still having issues?
If these steps don't resolve the problem, replace your power supply. Go to Device Service and Repair, register, and then select your Surface to start a service order.
