Samsung n145 plus (JP02 version) fan control not working #17

Thank you for you fan control module.
Seems it worked on my hardware (n145 plus JP02) BIOS 01HG
But actualy fan is not speed up at all.
I try to figure out the problem, but I'm not familiar with SABI and
you can direct me where I should start.

Here is output of the module.
[37257.055422] Easy slow down manager: checking for SABI support.
[37257.055732] Easy slow down manager: SABI is supported (f50d9)
[37257.055743] SABI header:
[37257.055752]  SMI Port Number = 0x00b2
[37257.055762]  SMI Interface Function = 0xc0
[37257.055771]  SMI enable memory buffer = 0xc1
[37257.055781]  SMI restore memory buffer = 0xc2
[37257.055790]  SABI data offset = 0x0f00
[37257.055800]  SABI data segment = 0xdf01
[37257.055809]  BIOS interface version = 0x32
[37257.055819]  KBD Launcher string = 0x53
[37257.055831] Easy slow down manager: SABI Interface = c00dff10

Then I echoed 2 to set fan speedup
echo 2 > /proc/easy_slow_down_manager
And there is no error, so I think command was successful, but no
actualy fan speedup.

There's some ACPI errors appears at dmesg, not sure it's SABI related
