You can disable or enable the Fn key functionality using the BIOS utility.
To disable or enable the function key (fn) in the BIOS follow the below steps:
• Hold the power button for at least five seconds to turn off the computer.
• Turn on the computer and immediately press the f10 key repeatedly, about once every second to open the BIOS setup window.
• Press the right-arrow or left-arrow keys to navigate to the System Configuration option.
• Press the up-arrow or down-arrow keys to navigate to the Action Keys Mode option, and then press the Enter key to display the Enable / Disable menu.
• Select the desired mode:
• Disabled: Requires pressing and holding the function key (fn) while pressing one of the f1 through f12 keys to use the action indicated on the action key.
• For example, on some computer models, if the Action Keys Mode is Disabled, pressing the f11 key will minimize and maximize a web browser if open. Alternatively, pressing and holding the fn + f11 keys will mute the sound.
• The action keys may vary depending on the model of notebook.
• Enabled: Requires pressing only one of the f1 through f12 keys to use the action as indicated on the action key.
• For example, on some computer models, if the Action Keys Mode is Enabled, pressing f11 will mute the sound as indicated on the action key. Alternatively, pressing and holding fn + f11 will minimize and maximize a web browser if open.
• The action keys may vary depending on the model of notebook.
• Press the f10 key to save the selection and restart the computer.
The function key (fn) option can be reset at any time.
