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:
