Function key in HP laptop

The steps to lock or unlock the function (Fn) key on an HP laptop can vary depending on the specific model of the laptop, but here are some general steps you can try:

To lock the Fn key:

1. Press and hold the "Fn" key on the keyboard.
2. While holding the "Fn" key, press the "Num Lock" key.
3. Release both keys.

This should lock the Fn key, meaning that the function keys (F1-F12) will be the default keys on the keyboard, and you'll need to hold the Fn key to access the alternate functions (such as volume or brightness controls).

To unlock the Fn key:

1. Press and hold the "Fn" key on the keyboard.
2. While holding the "Fn" key, press the "Num Lock" key again.
3. Release both keys.

This should unlock the Fn key, meaning that the alternate functions will be the default keys on the keyboard, and you'll need to hold the Fn key to access the function keys.

If this method doesn't work, you can try looking for a BIOS setting that controls the behavior of the Fn key. The steps to access the BIOS can vary depending on the model of the laptop, but you can usually do so by restarting the computer and pressing a specific key (such as F2 or Del) during the boot process to enter the BIOS setup utility. Look for a setting related to the Fn key or function key behavior, and adjust it as needed. Be careful when changing settings in the BIOS, as incorrect changes can cause problems with the computer.
