Answer 1

Try these in order:

Press Fn + Esc once.
- On many keyboards, this toggles Function Lock.
- After that, test F1, F2, and F3 again.
If the keys still do the wrong action, use Fn + F1/F2/F3.
- On keyboards with an Fn key, holding Fn while pressing the key uses the alternate command.
If the keyboard has an F Lock key, press it.
- F Lock Off = alternate functions work.
- F Lock On = standard F1, F2, F3 functions work.
If the goal is to make the keyboard easier to use while testing, open Start > Settings > Accessibility > Keyboard.
- Check whether Sticky keys or Filter keys are affecting key behavior.
- Windows logo key + Ctrl + O opens the on-screen keyboard for testing.
If none of that changes the behavior, check the Lenovo BIOS/firmware setting for function key behavior.
- Look for a setting that switches between Function Keys and Media/Action Keys.

Windows has no control over the actions associated to the function keys, because the actions vary from laptop to laptop, it is always the laptop manufacturer that controls the actions.

1

If pressing a function key does not product the correct action, try pressing Fn + the function key.

If that works, then press Fn + Esc to toggle off the function lock on your keyboard.

2

If that does not resolve the problem, boot your laptop into BIOS and search in there for a setting to toggle between Function Keys and Action/Media Keys.

If that setting is not available, open the Lenovo Vantage app on your laptop and check in the Input - User Defined Key section for anything that may be blocking those function keys.
