Fn keys

Let us try this. Some laptop models allow us to disable/enable Fn key by holding Fn key and press Esc.

So that, the volume and brightness can be changed without/with Fn key. Fn can be locked by Fn+Esc → volume and brightness can be changed without Fn key.

 

Volume keys

Since upgrading to Windows 10 my Lenovo keyboard volume keys now require the Fn key; i.e. Fn+F2 or Fn+F3. How do I go back to just using the F2/F3 keys as volume controls?

 

FN key always on

If you press “Num Lock" (might also be labeled "Num Lk”) (I’ve also seen it labeled “Pad Lock” for numeric Pad) it turns on the blue keys, and inverts the meaning of the “Fn” key – it’s a way to use that embedded numeric keypad without having to hold down the “Fn” key the entire time. To fix it, just find and press the “Num Lock” or “Pad Lock” key again. (Note, sometimes these keys are themselves “Fn” keys, so you may, or may not, need to also hold down the “Fn” key to get the right function.) Often there is an indicator light associated with the setting.
