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).

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.

Thanks for this! Rolling back the bios from 01.03.00 to 01.02.00 indeed fixed the fn lock function.

We have here HP Probook 450 G6. It came with BIOS version 1.2.xx (xx was for sure not 00, but I don't remember exact number). After upgrading to 1.3.00 FN LOCK function is not working, FN led stays off.

 

After BIOS downgrade back to 1.2.00, Windows 10 IS UNABLE TO BOOT. It freeze on HP logo screen with Windows 10 dots.

Windows will boot only in SAFE mode. Even Windows setup will not boot.

 

So downgrade is not solution to us. We are often using Fxx keys, so working FN LOCK is a must.

Hmmm, freezing can be caused by some HP drivers. You can investigate sys logs, try to find workaround disable some services or drivers... In another words try to dance with magic toubourine with unpredictable resaults.

 

But simply claim HP support to fix buggy BIOS!
