Reasons why the fn key doesn't work

One of the most common fn button failure problems is a physical failure due to water contacting the keyboard. When liquid gets on the text input device, an oxide film is created on the tracks of the board with a further violation of one of the matrices. As a result, current does not flow through them, and the fn button on a Samsung laptop does not work. Often the track on which the computer function key is located fails, as it is associated with many keyboard buttons.

Another reason is that the fn key is disabled by default, and in order to activate it, the user needs to press a combination of buttons, most often Fn + NumLock. This reason can also include the deactivated modesystem key in the BIOS environment.

The third and last reason could be a dirty keyboard. If debris gets under the keys, blocking their pressing may occur. This happens because the rubberized nozzle on the button is not pressed inward and does not contact the device board.

These are some of the most common reasons why the fn button does not work on a Samsung laptop.
