What to do if your Surface power supply or charger doesn’t work
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 power 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 the connector with a soft, dry, lint-free cloth, and check for any damage. (Replace damaged cables.) Plug the charger back into the power outlet and your Surface.
-
Plug it in the other way: Flip the connector on the charger 180 degrees, and then check to see if the LED light comes on and determine if your Surface starts charging again.
-
Try a different power source: Plug the charger into a different outlet, surge protector, or power strip.
-
If you're using a Surface Dock: If the Surface device battery is empty, first charge it using the power supply that came with your Surface. After that, try to charge it with the Surface Dock again.
-
Try using another Surface power supply or USB-C PD charger: If you have another Surface power supply available, try using that to charge your Surface. If your Surface has a USB-C port, try using a USB-C PD charger instead. If those work or if you don't have another Surface power supply or USB-C PD charger, start a service order for your power supply. Otherwise, start a service order for your Surface.
If your Surface power supply or charger still doesn't work, submit a service order
There's one last step you can take.
If these steps don't resolve the problem, you can submit a service order to Microsoft to access available repair or replacement options. Go to Device Service and Repair, register, and then select your Surface to start a service order.
