Buying a new laptop is always a very pleasant event. In the modern world, for many, the computer is not only entertainment, but also a source of additional income. Therefore, it is very annoying to have even its minor serviceability. Such troubles include cases when the fn button does not work. The reason for this may be several factors.
Lack of driverOften, 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 the driver for the specific model. After that, install them and restart the computer. If the problem was the lack of a driver, then after this procedure all the keyboard functions will be available.
Sticky keys
If the keys on the laptop do not work, then the reason may lie in their sticking. New devices rarely do this. But, if the fn button does not work in conjunction with several other keys, then it is 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 an alcohol solution. In the event that the laptop is just purchased, this is not recommended, because when disassembling it independently, the owner loses the warranty. It is better to contact a service center that will fix the problem, albeit in a longer time frame.
Also, do not engage in self-cleaning the keyboard in the case when you are not sure that you can carefully disassemble and assemble the laptop correctly. If you still decide to solve the problem yourself, then first examine the nuances of disassembling your model, and also remember the location of the keys on the panel.
Bios Settings
Another reason that the fn key does not work may be incorrect system setup in Bios. To fix this, you need to go into the settings by holding F2 or del at system startup. Next, select System Configuration and make the necessary changes depending on the problem. If the fn button does not work even after that, then you can try to switch other parameters related to Action Keys.
In some laptop models, there are malfunctions in which all the keys work, but only with their combination. So, it happens that
function keys are only active when pressed together with the fn button. The problem is also solved in the settings Bios-> System Configuration-> Action Keys Mode-> Disable.
In addition to mechanical and software causes of malfunctions, assembly errors or damage during delivery or storage may also have an effect. Sometimes the problem is that the fn button does not work correctly. The reason for this is often the Bios settings. In any case, for better and safer maintenance of your computer or laptop, you must contact specialized service centers or, at least, those people who have already had to solve such problems.
