Hi Martin -- I went through the steps outlined:

vanh...@reptar:~$ /lib/udev/findkeyboards
AT keyboard: input/event5

vanh...@reptar:~$ sudo /lib/udev/keymap input/event5 > orig-map.txt

... however when attempting to generate output with:

vanh...@reptar:~$ sudo /lib/udev/keymap -i input/event5

... no events are registered at all when using Function+up, or
Function+down.  Both Function+left/right (volume), and all the
directional keys work just fine:

vanh...@reptar:~$ sudo /lib/udev/keymap -i input/event5
[sudo] password for vanhoof:
Press ESC to finish
scan code: 0xC8   key code: up
scan code: 0xD0   key code: down
scan code: 0xCB   key code: left
scan code: 0xCD   key code: right
scan code: 0xAE   key code: volumedown
scan code: 0xB0   key code: volumeup
[...]
scan code: 0x01   key code: esc


I checked on Lenovo's site, and there are presently no BIOS updates
available for this laptop yet.


Just in-case it is needed, I'm attaching steps 4, and 5 here as well:

vanh...@reptar:~$ head /sys/class/dmi/id/sys_vendor
LENOVO
vanh...@reptar:~$ head /sys/class/dmi/id/product_name
3389


Could this just be a BIOS issue, or any other ideas?
