The Microsoft Surface Diagnostic Toolkit is a small, portable diagnostic tool that runs through a suite of tests to diagnose the hardware of Surface devices. The Microsoft Surface Diagnostic Toolkit executable file is less than 3 MB, which allows it to be distributed through email. It does not require installation, so it can be run directly from a USB stick or over the network. The Microsoft Surface Diagnostic Toolkit walks you through several tests of individual components including the touchscreen, cameras, and sensors.
The Microsoft Surface Diagnostic Toolkit runs several individual tests on a Surface device. Not all tests are applicable to every device. For example, the Home button test is not applicable to Surface Pro 4 where there is no Home button. You can specify which tests to run, or you can choose to run all tests. For tests that require external devices (such as testing output to an external display) but you do not have the required external device at the time of the test, you are given the option to skip the test. If a test fails, you are prompted to continue or stop testing at that time.
The Microsoft Surface Diagnostic Toolkit tests verify only the hardware of a Surface device and do not test or resolve issues with the operating system or software.
This tutorial will show you how to download and use the Microsoft Surface Diagnostic Toolkit on your Windows 8.1 and Windows 10 Surface device.
All Surface devices come with a Windows recovery partition that incudes information that allows you to refresh your device or reset Surface to its factory condition. In case you have any issues with the Surface, you could use the built-in recovery options.
If you ever have a problem getting Surface to start, or if the built-in recovery info has been removed from your Surface, then you can download the recovery image files you need from Microsoft and create a Surface USB recovery drive to boot from and use to access recovery tools and solve problems with your Surface.
This tutorial will show you how to download a recovery image for your Surface, and how to create and use a USB recovery drive from the downloaded recovery image.
