Default Programmable Button Operations

The function button (FN) located on the top panel is used to diagnose device failure or to perform firmware

restoration. After pressing the button, release it at the appropriate time to enter the required mode to either

troubleshoot issues in your computer or restore your computer to the default configuration. Refer to the

following illustration for detailed instructions:

The LED indicators behave differently when diagnosing a device failure compared to performing a firmware

restoration. See the following table for details:
