Brightness control on HD520?

[Borkie]

Hi, I managed to get Mojave 10.14.1 running on my Asus P2530 laptop, but one thing I couldn't get working even after three days of messing around is the brightness, which is always locked at maximum. I tried following RehabMan's guide, but it seems to not be working at all. Am I doing something wrong or my graphics chip is not compatible?

just add simple device PNLF into scope _SB with Whatevergreen kext load

 

 

Device (PNLF)
        {
            Name (_ADR, Zero)  // _ADR: Address
            Name (_HID, EisaId ("APP0002"))  // _HID: Hardware ID
            Name (_CID, "backlight")  // _CID: Compatible ID
            Name (_UID, 0x10)  // _UID: Unique ID
            Name (_STA, 0x0B)  // _STA: Status
        }

I'm still a bit of a noob about that, where should I put this code?
