Asus laptop special modding

-Manufacturer & Model: ASUS N61Jq
-Bios revision: N61Jq 212

The problem is simple to explain, the notebook is given with a simple keyboard (no backlit)
There is an existing keyboard model which works fine with my model but the backlight keys (Fn+F3: bright down and turn off/ Fn+F4: bright up and turn on) are not responding. Backlit power connector is present.

I don't want to make a hard-mod with solding wire to +5v/ground and have the backlight always ON or doing a complexe electrical schema to have 3 brightness or it...

I suppose the Fn keys routines are hold in the Bios, I have not found any apps to mod *.2xx type roms.. Perhaps not used good keywords in searchs.

So, can somebody look into the bios file if the Fn keys commands are somewhere and if FN+F3 and FN+F4 are disabled/missing and could be added?? Perhaps looking at a G60 bios for backlit commands


PS: excuse me if I make some mistakes about bios contents
PPS: excuse my not-really-good english because i'm french (excuse my president too )

 

If somebody knows how to dissassemble (or decode) and modify asus bioses with *.2xx extensions, i will ty to find someting interesting

 

OK, I take a look... so DSDT has to be the solution -> go everest software to find it but what are the softwares to use to mod it/implant the modded one? and also the simpliest soft to look in an EFI bios ? (I'm on windows 7 x64, but I find only soft for OS X)
thx


Euh, Everest told me that is an AMI bios ? normal or not ?


Edit: have looked into the dsdt table but i'm not sure to find sth...

isn't it better to work on dsdt extracted from the "bios" rom ? (i've tried to extract but everytime i get an error ...



I have something... but need to confirm and I did not find where is the FN+F3 and FN+F4 keys command
