Functional keys is locket to fn functions by default. I need to switch its for default functions (f1-f12) and use additional functions using fn+f* combination. But there is no option for doing it in efi settings. Fn lock function doesn't work too.

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).

HP Support Assistant has recommend upgrade to 1.3.00. So we done that.

After bios update FN LOCK function is not working, FN led stays off.

 

So we decided to downgrade BIOS. On support site is available only 1.1.00 and 1.2.00 for downgrade.
Because 1.2.00 was closest match to our original 1.2xx - we choose that.

After BIOS downgrade, 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 possible for us. We are often using Fxx keys, so working FN LOCK is a must.

HP, we need fix ASAP!
