My volume and brightness keys aren't controlling my volume and brightness. I know it has something to do with my fn key, because when I hold my fn key and press the volume or brightness, they do what they are supposed to do. How do I turn off the fn lock? I looked it up and tried holding down esc and fn, caps lock and fn and alt and fn but none of them worked. What do I do?

    The combination 'fn + shift' worked for me on hp Z Book windows 11. Note that on my keyboard's left 'shift' key, there is 'fn lock' marked on the bottom right. You may look for the same mark on other keys if this combination does not work for you!

    I have a Omnibook X and I had this problem for about a week, and alot of these anwsers didnt work for me. I realized you kinda have to look at your own keyboard. There should be at least one key that says "FN LOCK" in little letters (mines on my shift key.)

    Just hold down the FN key and then press the "FN LOCK" key (shift for me.)

    Hope this helps.

    On my Dell Laptop E6420

    THE solution is:

    Fn + F2 - This toggles the FUNCTION On or Off.

    My F2 key has a small LOCK ICON and in the same color as the Fn key.

    If you have a laptop from Lenovo and it has the Lenovo Vantage app installed, check all your systems/updates. It should be an app. There should be a section to click on device settings > input > scroll to FnLock and turn it on.

    I've been having the same issues where my Esc, Tab and 1 have completely stopped working, and I'm not too sure what to do, so I'm forced to hold down the Fn button to decrease/increase the sound and brightness. Figuring this out helped me a ton without having to hold down the Fn button, as the Fn stays locked now.

    Do you check BIOS/UEFI configuration?

    Restart your computer and access the BIOS or UEFI settings by pressing a specific key during startup (e.g., F2, Del, or Esc). Navigate to the Keyboard or Function Key Behavior section and look for an option to change the Fn lock behaviour. The specific option and location may vary depending on your computer's manufacturer and BIOS/UEFI version.
