Comment 14 for bug 1841039

I have HP 450 G6 as well.
Installing the latest firmware as described unfortunately did NOT fix the issue.

Just to clarify something with the others that have experienced and reported the issue ...

Please confirm that you are pressing Fn+F3/F4/F8 while the little led on the Fn key is lit.
If that is not the case, then you are actually pressing only F3/F4/F8 which worked just fine anyways.

So, to reproduce:
1) press Fn+Left Shift (Fn Lock) so that the led on Fn is lit.
2) press the combinations in question Fn+F3/F4/F8 and verify the keycodes are different with showkey.

Reason for this:
I thought it was fixed for a moment after installing the new firmware.
But, then I realized that the Fn lock is turned off.
