Fn HotKey driver for Lenovo Notebooks

Recommended Posts

greetings EmlyDinEsH

I have a Lenovo Thinkpad E440 I install the kext and I work the following hotkeys

Fn + F1 Disable audio

Fn + F2 Reduce audio

Fn + F3 Increase audio

I do not work

Fn + F4 Disable the microphone

Fn + F5 Decrease the brightness

Fn + F6 Increase brightness

Fn + F8 disable / enable wifi

I can not tell you if applying the patches to dsdt work, start in the world of hackintosh few weeks ago and still have much to learn.


Sorry for late reply, try new v1.2 and see. If not working then PM me your DSDT dump, system.log and ioreg.

Hi Great Job !

I finally found something that addresses my issue with Lenovo Ideapad Z500 's Fn Keys .

but when I patch my DSDT  it  doesn't compile

it gives the following error.

11829, 6126, syntax error, unexpected $end and premature End-Of-File


how do I fix that ?

the patches I used with MaciASL≠ are :

AC DC event notify patch

CFG patch

Fan control patch (G400s/Z500)

Model series Gxxx/Zxxx ID patch

Fn Brightness Keys Patch



Thanks in advance .

'could also be a side effect of an incorrectly decompiled DSDT table. Rehabman's always recommends to decompile with iasl line command and recompile with MacIASL. Version RM-1.31 (RM252.2) preferred and works always perfectly.

Post your file(s) so we can have a look.

I did follow the Rehabman's guide to make my DSDT and SSDT.
I fixed my problem by installing the latest Elantech smart touchpad  kext .
but I'd like to have those mods you made, enabled. like fan control...
here is my dsdt  I extracted it on my linux partition .
could you please patch it for me.
it compiles well and works before adding your patches .






I'm on El capitan lenovo Ideapad z500 i7
