Where s the fn key on a laptop? Why didn t I find it?

Common features of the FN key of the notebook The FN key does not play an input role in the laptop, it is a pure key combination like the CTRL key, the key combination composed of the FN key and other keys can be directly supported by the BIOS (this is the practice of most brands), or it can be at the software level (such as Sony's practice), of course, the most current form is hybrid, that is to say, some key combinations are directly supported by the BIOS and can be used in any environment, Some key combinations require additional software support in the operating system to take effect. Most FN key combinations are implemented using the FN key plus the ESC or F1 F12 key, but there are also some manufacturers (e.g. IBM, Compaq, and Sony) models that have some combinations with the FN key and the letter key, and most of these combinations are "secret techniques" for the average user:) and we will also share these special key combinations with you in this article.

The combination of the FN keys and the corresponding functions are generally uniform across the brand. Laptops generally have only one FN key, which is set between the Ctrl and Windows keys in the lower left corner of the keyboard: Of course, there are special ones, such as IBM putting it on the left side of the Ctrl key on the far left of the keyboard:

Some ultra-thin and light models of Japanese and Korean brands like to design a second fn key next to the up, down, left, and right arrow keys on the right side of the keyboard. In laptops, the FN shortcut key usually has two functions, one is to realize the adjustment and switching functions of the hardware, such as the adjustment of screen brightness, display switching, sleep and standby, etc., and the other is to supplement some keys that are on the standard desktop keyboard but not on the laptop, such as numlock, scrlock, break and even the page up and page down keys are commonly used in laptops to achieve the combination of fn keys and other keys, Some models can also use a combination of the FN key and some letter keys to implement the function of the numeric keypad. In order to be intuitive and convenient to operate, almost all laptops print the fn key in a different color (most commonly light purple or light blue), and print the icons of the combined functions in the same color for the keys that can be combined with the fn key, so that it looks intuitive.

Since the fn key needs to be combined with other keys to play a role, and most models of the fn key only one is located in the lower left corner of the keyboard, if the key to be matched with the fn key is located on the right side of the keyboard, it is inconvenient to operate with both hands, so many machines also provide the "stickiness" of the fn key function, that is to say, you don't have to press the fn key all the time, as long as you press it once, it simulates being in a state of pressing all the time, and then you can calmly find another key to realize the function of the key combination, and then press the fn key after completing the operation, it will return to the state of not pressing, so that it can adapt to different user environments, but even if it provides this function, it is turned off by default so as not to accidentally trigger it by the user.
