If you experience no sound after installing internal speakers, please follow the steps below to enable the Internal Speaker function in the Bioses.

Note: If your computer does not have internal speakers installed, please do not enable this setting, as it may result in the system having no audio output.

1. Ensure that the internal speaker hardware has been installed correctly.

4. Once in the Bioses screen, press the [F7] key on your keyboard, or click [Advanced Mode]① on the screen.
   
5. In Advanced Mode, select [Security]②, then select [I/O Interface Security]③.
