Naturally, this is the key that is used to perform different functions with the keyboard of our laptop. At first glance, we can see that this key has a red or blue color.

In addition to this, there are other keys that have the same color but with a smaller symbol or word and at the bottom of these. This is to activate any of the functions that are marked that way.

For example, on some keyboards, the arrow keys are used to lower and raise the volume or lower and raise the brightness of the screen. We achieve this by combining any of the arrow keys together with the Fn key.

Now, we will explain how you can deactivate this key or solve the problem of an inverted Fn key or when it has stopped working as if it had been blocked.

However, this is one of the solutions. In some forums, they have shown that it can also be solved if you hold down the Fn and the number lock keys respectively.

The latter will serve us more than anything for those Desktop computers. Despite having all these methods, we must be clear that it will change a lot depending on the computer or laptop you have.

The important thing is that you take into account that you must look for the padlock symbol with the number nine inside to specify this function. In some cases, pressing the Fn + F11 key has helped them.

  2. You should completely shut down the computer. You can press and hold the power button for about 5 minutes and that way we will also have turned it off.
  3. Now, you will need to turn on the computer again.
  4. Immediately when it is turning on, you will need to press the F10 key consecutively a few times.

What does it mean to turn the Fn key or action keys on and off?

When we have the Fn key permanently activated, then we will not need to use the Fn key so that we can use those function keys.

Which are basically those that have other symbols or words corresponding to the color of the Fn key.

An example of this we have with respect to the F8 key, which in HP computers helps us to raise or lower the volume.

Or also when we press this key together with Fn, which helps us to raise or lower the zoom of a web page.

Now, when we have this option in the “deactivated” mode, then it will be necessary to use the Fn key to perform the different secondary functions that all these keys have.

Like for example, when we use the F1 key to open a corresponding window with help. Or also when we are pressing this key together with the Fn, which helps us to have the computer in sleep mode.

How to disable the Fn key on Lenovo?

How to disable the Fn key on Lenovo

In this case, we will talk about when a Lenovo laptop has the Fn key permanently activated and you want to deactivate it.

The following method is to be applied on a computer running Windows 8.1 operating system.

Tutorial to disable the Fn key on Lenovo

  1. Turn off your Lenovo laptop.
  2. Next, you must turn it on and press while the F10 key is initializing several times consecutively.
  3. In this way, we have been able to access the BIOS of our computer and the corresponding menu will appear.
  4. We must go down with the arrow keys on our keyboard to where it says “Settings”.
  5. There we must select an option called “Hotkey Mode”, which basically deals with the hotkey mode.
  6. This mode must be set as “disabled”, that is, as disabled.
  7. After that, you must save the configuration you have made by pressing the F10 key.
  8. And we finish by pressing the ENTER or INTRO key on our keyboard.

How are the keys when we deactivate the Fn key?

When this option is found to be activated, then the corresponding hotkey, which is the Fx, will be activated by pressing it. And to use the inherited Fx key, we will have to perform the key combination of Fn + Fn.

However, if we have this option as disabled or deactivated, then we will have that the key that corresponds to the shortcut is obtained with the combination on the keyboard Fn + Fx. And for the legacy, it is obtained by pressing only Fx.

It should be noted that the command that is pressed combining the Fn key and the Esc key may still be working, but it has not been activated once we restart the computer.

This is very easy to solve. Most of the time this happens is because the BIOS of our computer is totally out of date and you must look for the update. Other times it is the software of these keys.

The same happens when this Hotkey mode does not appear on the BIOS screen, it is recommended that the person quickly update their BIOS to solve it.
