Check the power cable connection
Make sure the power cable is plugged in securely.
Note: When you unplug the power cable from your Surface Studio 1, Surface Studio 2, or Surface Studio 2+, unplug it from the wall first. The plug that’s attached to the base has a lock to keep it in place when you move your Surface Studio, Surface Studio 2, or Surface Studio 2+. If you need to unplug the power cable from the base, slide the plug away from the base to release the lock.
