  • Windows update and system repair

  • Power supply and battery

  • Touchscreen and display brightness

  • Speakers and microphone

  • Network connectivity

  • Memory and storage


  • If you're using the Surface Diagnostic Toolkit on a work device, go to Surface Tools for IT, and then download the Surface Diagnostic Toolkit for Business.

  • If your work or school manages your Surface, check with your IT department before running the tool.
