Yes, you should reinstall the original kernel to replace the test kernel
provided by me, and you have to add back that line to alsa-base.conf so
that LEDs will work.

I suggest you to report the F11 LED issue to upstream kernel at

This fix will be included in all kernels in the future, but that will take
some time as it takes time to backport.

You received this bug notification because you are a member of Kernel

  HP ProBook 470 G5, LED's in Hotkeys f5, f8 and f11 without function

Status in linux package in Ubuntu:

Bug description:
  Notebook: HP ProBook 470 G5 (3KZ03EA)
  Distro: Linux Mint 19.1 Tessa
  Desktop: Cinnamon 4.0.8
  Kernel: 4.15.0-43-generic x86_64 bits: 64

  The functions of all hotkeys are given, but the LED's in the [f5]
  Speaker-mute, [f8] Micro-mute and [f11] Wireless on/off Buttons do not
  show the status. Disturbing is also the LED in [f11] permanently lit.

  This is my first bug report to launchpad and I ask for leniency and
  troubleshooting support.

  I created 12 logs, unfortunately the upload did not work at once:

  xev keypress test.txt

  Previous attempts:
  My on-board search for other HP ProBook Hotkey LED-issues led me to this bug 
report: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1705586

  but the solution to the file: /etc/modprobe.d/alsa-base.conf
  to supplement the entry: options snd-hda-intel mode = mute-led-gpio

  did not lead to the solution here. Presumably, the failure results
  from a different ubuntu-version and/or a another kernel.
