The Lenovo™ PC Diagnostics 2.0 app is designed to assist users with the display and debug of diagnostic information available on select Lenovo ThinkPad™ models (ThinkPad 13 2nd gen or later) and select ThinkStation™ (models P520, P720, P920). Downloading and launching this application will allow you to acquire the audio tones that are produced by your ThinkPad or ThinkStation when an abnormal or error condition is present. The tones are then translated to a specific error message which will be displayed on your smartphone. The application requires your phone to have an operating system level of Android v12 and above. Operating systems below v4.0.3 will not work with this application.
