-Manufacturer & Model: ASUS N61Jq
-Bios revision: N61Jq 212
-Bios Type: American Megatrends
-Bios Download Link: http://dlcdnet.asus.com/pub/ASUS/nb/N61J/N61JqAS212.zip

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 and for my not-so-good english

Have posted my problem in another forum, their answer about bios was that there is an EFI bios and that I should look into the DSDT which was a simplier method to enable backlit with ACPI tables ...

Code:
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

i think a N73 or a G60 bios has the backlit code, for the N73 : http://dlcdnet.asus.com/pub/ASUS/nb/N73J...QAS207.zip

The connector has +5V and ground ... so i don't know why the keyboard doesn't want to shine when pressing FN F3 or F4... laptops with original backlit keyboards have the backlit flash/wink when starting computer and not me.

Thanks
