"CPU fan control not available" on Samsung 900X3c

[microsome]

Using Fn+F11 shows the message "CPU fan control not available" and the current temperature. In 12.10 multiple pressing of these button switches from silent to normal and I think something like turbo/heavy use resulting in increasing usage of the fan.

In Ubuntu 13.04 this function is gone. In addition the keyboard back-light buttons (Fn+F9 and Fn+F10) invoke the message but I can not modify the brightness. It is always at max. More strange this is independent whether the light is on or off.

Please follow the steps in /usr/share/doc/udev/README.keymap.txt.gz to check whether the keymap needs to be updated, and the right scan code/keycode mapping. Thanks!

I checked for errors using sudo /lib/udev/keymap -i input/event3
The result for Fn+F11 is: scan code: 0xB3 key code: prog3

Don't know what prog3 means.

Here are the contents of the relevant files, strangely Fn+F11 is defined here as SIlentmode???

In addition I got these messages for Fn+F6, Fn+F7 and Fn+F8, respectively, even there are working:

Still have this problem on 16.10, silent mode not available, fan control - none.
