Lenovo PC Diagnostics is a handy tool that helps troubleshoot issues on certain Lenovo ThinkPad™ models. To use it, you need an Android phone or tablet with an operating system of v4.0.3 or higher. Simply download the app and run it. If your ThinkPad or ThinkStation encounters a problem, it'll make a unique sound. This app will pick up that sound, decode it, and display a specific error message on your device to help you understand what's wrong.

It works like a translator between your Lenovo ThinkPad or ThinkStation and you. This way, you can understand and address any issues more efficiently.
