Introduction to the function of "Fn" button for different brand notebooks

"FN" means "function", which is used to form key combinations with other keys to achieve control. It is a key that appears in the lower left corner of the notebook and netbook keyboard. Some notebooks put the CTRL key in the lower left corner, and FN is in the bottom row of the keyboard from the left to the second position. "Fn" with a lot of blue engraved, but also useful green, purple, and the combination of keys to implement the function of the same color on the other key to express. These key combinations can be used to adjust hardware (hibernate, toggle display), or to implement keys that are omitted from the notebook on the desktop.

Although this layout design in the industry has been controversial, but for the old user does not affect. The FN key does not function as input in the notebook, it is the same as the CTRL key, and the combination of the FN key and the other keys can be directly supported by the BIOS (which is the practice of most brands), or it can be software level (e.g. Sony's approach), Of course, the most current form is mixed, that is to say, some key combinations are directly supported by BIOS in any environment, and some key combinations require additional software support in the operating system to be effective.

Most FN combinations are implemented using the FN key plus ESC or the F1~F12 key, but there are some vendors (such as IBM, Compaq, and Sony) that have a combination of the FN key and the letter key, and most of these combinations are "secret" to the average user: Below we will also share these special key combinations. The combination of the FN key and the corresponding function is generally unified in the whole brand. Fn + up/down key to adjust the brightness of the display; Fn + SAS key to turn on or off the external CRT monitor or projector.
