The fn button does not work: causes and solutions

Buying a new laptop is always a very pleasant experience. In today's world, for many, a computer is not only entertainment, but also a source of additional earnings. Therefore, it is very annoying to have even its small serviceability. Such troubles include cases when the fn button does not work. The reason for this may be several factors.

Lack of driver

Often, the configuration of the laptop provides for automatic detection of the keyboard and its functionality, but there are exceptions to this rule. In this case, you need to go to the official website of the laptop manufacturer and find drivers for a particular model. After that, install them and reboot the computer. If the problem was in the absence of the driver, then after the specified procedure all the functions of the keyboard will be available.

Key Sticking

If the keys on the laptop do not work, then the cause may be covered in their sticking. This happens rarely with new devices. But, if the fn button does not work together with several other keys, then it's likely that they are stuck. To eliminate this kind of malfunction, it is necessary to open the laptop and clean the buttons and keyboard panel with alcohol. In the event that the laptop is only purchased, this is not recommended; When self-disassembly, the owner loses the guarantee. It is better to contact the service center, which will fix the malfunction, though for a longer time.

Also, do not clean up the keyboard yourself if you are not sure that you will be able to disassemble and correctly assemble the laptop. If you still decide to solve the problem on your own, then first examine the nuances of disassembly of your model, and also remember the location of the keys on the panel.

Bios settings

Another reason that the fn key does not work is that the Bios system may not be configured correctly. To fix this, you need to go into the settings by holding F2 or del when the system boots. Next, select the System Configuration item and make the necessary changes, depending on the problem. If the fn button does not work after that, you can try switching other parameters related to Action Keys.

In some models of laptops there are malfunctions, in which all keys work, but only when they are combined. So, it happens that the function keys are active only when you press the fn button together. The problem is also solved in the Bios-> System Configuration-> Action Keys Mode-> Disable settings.

In addition to the mechanical and software faults, it may also be influenced by errors during assembly or damage during delivery or storage. Sometimes the problem is that the fn button does not work properly. The reason for this often lies in the Bios settings. In any case, for better and safer servicing of your computer or laptop, you need to contact specialized service centers, or at least to those people who have already had to solve similar problems.
