Surface tablet 11 not booting

Try these steps in order:

1. Force a shutdown and restart
   1. Press and hold the power button for about 20 seconds, until the Surface turns off and the logo screen disappears.
   2. Keep holding until the Windows or Surface logo appears again, then release the power button.
   3. If Windows still does not boot past the flashing logo, continue below.
2. Disconnect accessories and retry
   1. Unplug all USB devices, SD cards, external monitors, Type Cover, Surface Dock, and any other accessories.
   2. Connect the original Surface power supply and charge for at least 15 minutes.
   3. Press the power button once to turn it on and see if it now passes the logo screen.
3. Boot from a USB recovery drive and reset If the device still will not boot, use a USB recovery drive to repair or reset Windows:
   1. On another PC, create a Surface USB recovery drive as described in Creating and using a USB recovery drive for Surface.
   2. Shut down the Surface.
   3. Insert the USB recovery drive into the Surface.
   4. Press and hold the volume-down button, then press and release the power button.
   5. When the Surface logo appears, release the volume-down button.
   6. Follow the on-screen instructions to repair or reset Windows from the recovery environment.
4. If Windows still will not start If the device remains stuck at the logo screen even after attempting a USB recovery/reset, service is likely required. Use the service options to check warranty, create a service order, or find an in-person service center.
