Ok. I had the same problems than you. Now I always upgrade using a live-cd.
Set to invalid.
But feel free to reopen it if necessary.

Sound keys do not work on HP Compaq nx8220 (regression)

Solved on my side.
I've been updating distributions using update-manager for past 3 years.
Booting 8.10 live-cd and seeing keys working properly I reinstalled the
system (but kept /home directory).
After booting into freshly installed ubuntu, keys were still not
working. Then I checked Keyboard
1. What the key *should* do.
These are 3 sound keys: Mute volume, lower volume and raise volume. Mute volume
key contains LED indicator which is turned on when volume is muted.
2. What keycode (magic number) the key produces on your laptop.
(used method 4)
121 XF86AudioMute
122

More info.
Sound control works fine from Volume control in gnome. Mute LED
indicator on sound key is correctly switched on/off when muting/un-
muting sound from Volume control.

thank for you report but to be able to fix the hotkeys on your laptop we
need three things:
1. What the key *should* do.
2. What keycode (magic number) the key produces on your laptop.
3. How to identify your laptop by the manufacturer and model.
You can see the following documentation
