Hi, thanks for this one, but AsusNBFnKeys.kext is not loaded after replacing DSDT.aml you've send. Is there any other way to remap FN+PauseBreak and FN+ScrLK with FN+F5 and FN+F6? p.s. can you look at https://osxlatitude.com/index.php?/topic/1946-complete-applehda-patching-guide/?p=23412 regarding AppleHDA mic problem? Thanks for help! -- best regards fingerr

Hi EMlyDinEsH, Unfortunately your kext doesn't work. But I've got kext and guide from http://www.insanelymac.com/forum/topic/287133-guide-backlight-brightness-for-intel-80860046-1st-gen-hd-gma-5700mhd/ working (with modifications from post 68 by jerrywilborn). One thing is I can control brightness using FN+PauseBreak and FN+Delete not by default Asus ones FN+F5 and FN+F6. Is there a way to change this? Second thing is, using either your or other kext my LCDD is not detected, log says : 04.10.2013 22:55:34,000 kernel[0]: ACPIBacklightPanel: Version 1.2 04.10.2013 23:33:57,000 kernel[0]: ACPIBacklightPanel: ACPI Methods _DOS _BCL _BCM _BQC found.

I've tried many changes and adjustments to DSDT including changing device name from GFX0 to IGPU to be only one (I have optimus equipped notebook so there are few GFX0 entries). Can you have a look at my current DSDTand check why LCDD is not detected? Thanks in advance and best regards, fingerr. DSDT.aml.zip

Hi, you've put PLNF device beyond Scope _SB. Move your PLNF section just before last } in _SB scope: now your DSDT looks like this: .... } } // <- this one to remove Device (PNLF) { Name (_HID, EisaId ("APP0002")) Name (_CID, "backlight") Name (_UID, 0x0E) Name (_STA, 0x0B) Method (_BCL, 0, NotSerialized) { Return (\_SB.PCI0.GFX0.LCDD._BCL ()) } Method (_BCM, 1, NotSerialized) { Store (One, \_SB.PCI0.GFX0.BCMD) Store (\_SB.PCI0.GFX0.GCBL (Arg0), Local0) Subtract (0x0A, Local0, LBTN) \_SB.PCI0.SBRG.EC0.STBR () } Method (_BQC, 0, NotSerialized) { Return (\_SB.PCI0.GFX0.LCDD._BQC ()) } Method (_DOS, 1, NotSerialized) { \_SB.PCI0.GFX0._DOS (Arg0) } } so you have to delete one "}" above and device PLNF and add one just after "}" closing PLNF device. SO it'll look like this: .... } Device (PNLF) { Name (_HID, EisaId ("APP0002")) Name (_CID, "backlight") Name (_UID, 0x0E) Name (_STA, 0x0B) Method (_BCL, 0, NotSerialized) { Return (\_SB.PCI0.GFX0.LCDD._BCL ()) } Method (_BCM, 1, NotSerialized) { Store (One, \_SB.PCI0.GFX0.BCMD) Store (\_SB.PCI0.GFX0.GCBL (Arg0), Local0) Subtract (0x0A, Local0, LBTN) \_SB.PCI0.SBRG.EC0.STBR () } Method (_BQC, 0, NotSerialized) { Return (\_SB.PCI0.GFX0.LCDD._BQC ()) } Method (_DOS, 1, NotSerialized) { \_SB.PCI0.GFX0._DOS (Arg0) } } } // <-this one to add .... -- best regards fingerr

but it only hapen once at first boot after kext is loaded for first time, now lgo says: 04.10.2013 10:22:57,000 kernel[0]: AsusACPIBacklightPanel: ACPI Methods _DOS _BCL _BCM _BQC found.

Hi EMlyDinEsH, I have Asus U30Jc (1st gen IntelHD graphics + Nvidia 310M disabled via DSDT to save battery) and I can change brightness OOB using "original" keys (Fn+F5,Fn+F6 ) but slider is not working and I there is no bezel (bezel appears when i press Fn+PauseBreak, Fn+Delete but does nothing and seems both act as to increase brightness). Please find attached my DSDT and tell if this can work on this notebook. kernel log says: 04.10.2013 00:06:08,000 kernel[0]: AsusACPIBacklightPanel: ACPI Methods _DOS _BCL _BCM _BQC found.

Hi EMlyDinEsH, your guide is excellent but for me it is a "science fiction " May I ask you to look at my AppleHDA and codec dump? This kext is from guy from other forum who tried to patch it for me (using layout-id 12) and sound output is working but mic is strange thing. I can see it in devices and when I go to audio input setting, I can also see record level bar is showing activity (tapping laptop chasis with fingers) but when I try to record something using audacity (or making skype test call) playback of recording is very quiet and noisy (tapping fingers) or even when I try to shout. It looks like Mic has very low sensivity (Mic itself is OK, tested under ubuntu). Please have mercy and take a look at my files. --EDIT-- during boot log says: 03.10.2013 23:04:21,000 kernel[0]: Sound assertion - Command/Response TIMED OUT and ( kRequestStateMatch == fCodecRequest->state = 2 ), fCodecRequest->command->codec: 0xffffff800ef64500, fCodecRequest->command->verb: 0x3017FF00, fPoweredDown: 0 I don't know if this is sth important. p.s. sorry for my english, I'm not native. -- Thanks in advance and best regards, fingerr.
