Bios Mods -The Best BIOS Update and Modification Source

-Manufacturer & Model: ASUS N61Jq

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

hello there I will try to hlep you as best I can, I will also need the bios rom for the model the back lit keyboard is designed for. thx! Big Grin

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
