The function key denoted by “Fn” is mostly located at the laptop keyboard’s left bottom. This key offers some useful features to control the different functions of a laptop.
Holding the “Fn” key along with keys from F1 to F12 can perform different functions. You can perform multiple functions such as dimming the backlight, muting, increasing or decreasing the volume, enabling or disabling Wi-Fi, lock your system and various other features.
However, the “Fn” key on itself is not on or off. Some other settings might alter its functionality, and we are going to explore it further.
How to turn on Function Key?
First of all, go to the start menu and select all program. After that, select Toshiba from there. It will lead you to the next menu tab.
After that, go to utilities and then move on to the accessibility menu.
Once you have reached the accessibility menu, turn on the “Fn” key option from the menu. It will enable the “Fn” key, and the key would work along with other keys from F1 to F12. You might set the pattern of events there and alter further options related to “Fn” key. After all of that, click on the Ok tab.
Check the key
Now that you have enabled the “Fn” key, it’s time to verify if it’s working or not. You can hold the “Fn” key and press the top row’s backlight dimming button on the keyboard. If the backlight gets dim, then the key is working fine, the problem is resolved.
If the key is still not working after enabling it in the settings, it might be a hardware issue, and you might need to replace your keyboard of the laptop or computer system.
