Joseph,
I already tried to bisect kernel, but part of kernels hangs at boot and
I was unable to get any results. At mesa bugtracker I found workeraund,
if I disable CONFIG_HOTPLUG_PCI_ACPI option in kernel config all start
to work fine.

I've checked provided kernel and seems nothing has changed. Keys still
does't work and dmesg is sielent when I'm pressing mic mute.
For Fn+F10 it seems that the closest behavior would be to take selective
screenshot. But if there is no such event defined that it might be
mapped as a generic Fn
With v2 both keyboard and mouse from Lenovo Essentials set stopped to
work. Fortunately I had a replacement so I still was able to check what
happens. Seems that they stopped to be recognized as input devices, at
least there were no messages like following in dmesg
input: Primax Lenovo Essential
Keyboard worked with new kernel, however Fn+F4 still doesn't functional. I've
also noticed that mouse middle button stopped to work (both scrolling and
clicking) on this version.
dmesg doesn't show anything on pressing Fn+F4.

I've noticed that on every boot numerous errors appears:

Hi Chris, difference between full log and one I attached to previous
comment is that in the full one contained line "usage 0 hid: 0x0c
index 0x00 code 0x00 type 0x0" repeated endlessly. I rebooted system
once log file was filled with that line up to ~150 mb. If anything else
should be in
Thank you for clarification. Yes, system looks stable. The only thing
that bothers is that these messages are visible for a moment during
power off/suspend.
Please close this ticket

I believe you are talking about v7 kernel. I've tried it and for this
version dmesg was sielent on Fn+F4 and Fn+F10 pressing.

With v7 it seems that Fn+F4 and Fn+F10 still do nothing, however other media
keys got Mute Mic mapping as well as their primary function. For example if I
press Vol+ I hear that volume increased but also GNOME shows that microphone
become muted. This happens for mute, vol+, vol- and playback
No worries, thats might happen for everyone.
Some good news, now there is some reaction on both keys in dmesg:
[ 28.599434] (efault) data 0x0:0x00x0
Message is the same for Fn+F4 and Fn+F10.
Mouse still work in weird way with mouse wheel not working. There is
also a quirk that restart entry
Here what I was able to extract with the latest kernel:
Fn+F4
[ 44.615947] lenovo_raw_event data 0x1:0x0:0x0
