## <ahref=""id="the-tests--"></a>The tests
## The tests
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.

### Windows Update
#### Windows Update
This test checks for any outstanding Windows updates and will prompt you to install those updates before you proceed to other tests. It is important to keep a Surface device up to date with the latest Windows updates, including drivers and firmware for the Surface device. The success of some of the tests that are performed later in the task sequence depend on these updated drivers and firmware. You will be prompted to restart the device if required by Windows Update. If you must restart the device, you will need to start the Microsoft Surface Diagnostic Toolkit again.

#### Device information
This test reads the Device ID and serial number in addition to basic system information such as device model, operating system version, processor, memory, and storage. The Device ID is recorded in the name of the log file and can be used to identify a log file for a specific device. Several system log files are also collected, including update and rollback logs, and output from several Windows built-in tools, such as [DirectX Diagnostics](http://go.microsoft.com/fwlink/p/?LinkId=746476) and [System Information](http://go.microsoft.com/fwlink/p/?LinkId=746477), power configuration, disk health, and event logs.

>**Note:** A Surface Type Cover is required for this test.
If a Surface Type Cover is not detected, the test prompts you to connect the Type Cover. When a Type Cover is detected the test prompts you to use the keyboard and touchpad. The cursor should move while you swipe the touchpad, and the keyboard Windows key should bring up the Start menu or Start screen to successfully pass this test. You can skip this test if a Type Cover is not used with the Surface device.

This test is essentially the same as the Type Cover test, except the integrated keyboard in the Surface Book base is tested rather than the Type Cover. Move the cursor and use the Windows key to bring up the Start menu to confirm that the touchpad and keyboard are operating successfully. This test will display the status of cursor movement and keyboard input for you to verify. Press **ESC** to complete the test.

>**Note:** This test is only applicable to Surface Book.
Depending on which mode Surface Book is in, different batteries are used to power the device. When Surface Book is in clipboard mode (detached form the keyboard) it uses an internal battery, and when it is connected in either laptop mode or canvas mode it uses different connections to the battery in the keyboard. In canvas mode, the screen is connected to the keyboard so that when the device is closed, the screen remains face-up and visible. Connect the Surface Book to the keyboard in this manner for the test to automatically proceed.

Performance and diagnostic trace logs are recorded from Performance Monitor for 30 seconds and collected in the .zip file output of the Microsoft Surface Diagnostic Toolkit by this test. You can analyze these trace logs with the [Windows Performance Analyzer](http://go.microsoft.com/fwlink/p/?LinkId=746486) to identify causes of application crashes, performance issues, or other undesirable behavior in Windows.

### Crash dump collection
#### Crash dump collection
If your Surface device has encountered an error that caused the device to fail or produce a blue screen error, this stage of the Microsoft Surface Diagnostic Toolkit records the information from the automatically recorded crash dump files in the diagnostic log. You can use these crash dump files to identify a faulty driver, hardware component, or application through analysis. Use the [Windows Debugging Tool](http://go.microsoft.com/fwlink/p/?LinkId=746488) to analyze these files. If you are not familiar with the analysis of crash dump files, you can describe your issue and post a link to your crash dump files (uploaded to OneDrive or another file sharing service) in the [Windows TechNet Forums](http://go.microsoft.com/fwlink/p/?LinkId=746489).
