Fn lock not working

HP ProBook 440 G6
Microsoft Windows 10 (64-bit)

Hi!

I have problem with Fn lock function and Fn + Fxx functionality. Now Fn works in inverse manner and Fn lock not working at all. Changing BIOS settings has no effect.

Note: I'm upgraded my new notebook from preinstalled FreeDOS to my own copy of latest (1903) Windows 10 Pro. Then I've downloaded HP Support Assistant and installed all HP software including HP Hotkey Support (HP Inc. - 6.2.50.1).

I've found solution: it is latest BIOS 01.03.00 firmware problem. After rollback to 01.02.00 Fn lock begin works properly.

Seems HP QA  owe me pair beers 🙂

HP provides separate installers without restrictions - they do all things perfectly. I've do tthis twice - first of all i've instaled fresh version with Fn bug, then downgraded to previous.

Choose your OS here https://support.hp.com/us-en/drivers/selfservice/hp-probook-440-g6-notebook-pc/23200928

Then go to BIOS->Details->See full details->Revision History.

May be you don't need to choose OS for BIOS upgrade utility, but i've do it.
