    -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 (remove space)



    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 :biggrin:)

    Doesn't work this way.
    If you want brightness control you should look at the laptop's DSDT and work from there because Brightness is govern by ACPI and ACPI is determined by DSDT Codes.
    And although the extension is .206 I believe it is still AMI BIOS (I did some BIOS Mods before with .number extension but it is the same type of BIOS just trying to trick you).
    Just change the extension to make the BIOS Tools accept it.

    Actually That's an EFI BIOS.

    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 ... :confused:



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

    Code:
                Method (GLKB, 1, NotSerialized)
                {
                    If (LEqual (Arg0, 0x01))
                    {
                        Store (\_SB.PCI0.SBRG.EC0.RRAM (0x0449), Local0)
                        And (Local0, 0x02, Local0)
                        If (Local0)
                        {
                            Return (One)
                        }
                        Else
                        {
                            Return (Zero)
                        }
                    }
                    Else
                    {
                        If (LEqual (Arg0, 0x02))
                        {
                            Return (KBLV)
                        }
                        Else
                        {
                            If (LEqual (Arg0, 0x03))
                            {
                                Return (0x80)
                            }
                        }
                    }
    
                    Return (Ones)
                }
