  1. Sony Vaio VPCF115FM Discussion: DSDT Injection

    Thanks for that but unfortunately it doesn't work. There is no change at all in the behaviour of the brightness slide control. If I move the control from the rightmost position (full brightness) leftwards, the screen darkens almost imperceptibly but at around 70% position from left to right the screen turns off completely and stays off (unless I press the "display off" button in the keyboard to turn it on). This is the same behaviour I've got with the previous DSDT. Alexei

    Hello! Has anyone managed to enable brightness control on any VAIO that suffered with the now solved black screen issue? My VPCF12M0E/B has the OSX's brightness slide control (System Preferences->Displays) enabled but it doesn't work properly. It is always on max brightness and if I move the slide to the left, the brightness is reduced only slightly then the display is turned off (I can turn the display on again by using the dedicated key on the VAIO's keyboard). I've tried a few things like Rehabman's ACPIBrightness.kext (unsuitable for NVIDIA cards) and GenericBrightness.kext to no avail. Cheers, Alexei

    Hi guys, I was quite busy these last days but finally was able to continue the tests on my VAIO. @jl4c: I tried both versions of DSDT.aml you sent me (v1 and v2) but the results are similar to art.sormy's, that is: MSRDumper.kext: no P states at all DPCIManager: P states vary as (7, 8, 9, 10, 11, 13) according to the processor load (7=idle, 13=heavy work) Also, AppleLPC.kext does not load. Got the same results with this one: it doesn't work, doesn't detect the network cable. What is the exact model of your WLAN card? Is it the stock one or did you replace it? Does it work on OSX out of the box? I'd rather buy a WLAN card as long as it is 100% compatible. Regarding your touchpad's issues, try this modified version of VoodooPS2: http://www.hackintoshosx.com/files/file/3896-alps-multitouch-trackpad-kext-for-mavericks/ This one still have minor issues but is by far the best one I found (anyways, my VAIO touchpad is crappy even on Windows). You should be able to tweak it on Trackpad (System Preferences) wich is quite nice. Did you manage to fix the "About this Mac" bug? Finally, can you share your Clover's config.plist? I think I messed up mine because the power button is not working any more Thanks guys!

    Which dsdt? Did you forget to attach it?

    I didn't expect you'd reply so quickly so I spent some time analysing your fixes to art.sormy's DSDT and by comparison I applied those fixes to my original DSDT and guess what? It works flawlessly! I got full acceleration on my VAIO's internal screen. Awesome! (just a thought: I tried a similar fix to override EDID few months ago but it didn't work. I guess the problem was either that I didn't try it with Clover or the backlight section was missing.) Of course I also tried the fixed DSDT you sent me and it works exactly the same as mine as far as I can tell. The overall performance is excellent, now OSX runs really fast (and it is not even installed on the SSD drive!). I noticed though that our DSDT versions are different in size so I will keep using yours. My main issues now are that I don't have any network capabilities (Intel 6200AGN WLAN and Marvell 88e8057 Ethernet are not supported at all). Also the new DSDT doesn't fix HDAudio. Here is my IOReg dumped from a session running with your fixed DSDT: VPCF12M0E_ioreg_fixed.zip I can't say anything about the state on my VAIO of the minor issues like speedstep that art.sormy has reported (don't really know how to test) but of course I'm willing to help, even though my goal now is to get network and audio working! Many thanks!!! Are you actually able to connect to a network after applying this fix? I gave it a try and a new network device is available now but only get "Cable unplugged" on network configuration, even if the cable is actually connected and its port on the hub flashes. The system log is also flooded with an error message regarding the Yukon2 device that cannot be initialised. Any thoughts? Thanks!

    Hello jl4c and art.sormy, Wow, that's a nice finding! Finally the internal screen is working on a Vaio F series! I have a Sony VAIO VPCF12M0E/B which is almost identical to art.sormy's VAIO: the only difference I can tell is the WLAN (Intel 6200), graphics card (NVIDIA GeForce G330M) and the internal screen is Full HD. I have exactly the same issues described by art.sormy regarding the internal screen and certainly other minor issues (e.g. HDA audio doesn't work without VoodooHDA). I send attached all relevant files: From Linux: - DSDT.aml - edid-lvds.bin - lspci From OSX 10.9 booted with latest Clover EFI (2k_r2939), nv_disable=1 and Inject NVDIA: - ioreg files @jl4c: Could you try your method to see if it makes the internal screen work properly? Or alternatively explain how to fix it? @art.sormy: What is this AppleYukon2 Info.plist patch you mentioned in your previous post? Currently the ethernet is not working. Many thanks! VPCF12M0E.zip

    Hey, some guys managed to turn on the internal screen and brightness control, even though there is no image. Check this out: http://www.insanelymac.com/forum/topic/300715-vaio-users-black-screen-after-boot/ Maybe you guys can help them further?

    It seems no one is working on this issue any more... But I was bored and then decided to search on the Internet for other similar problems and found this: http://www.insanelymac.com/forum/topic/285692-nvcap-injection-in-mountain-lion/ Have any of you ever tried this method?

    Hey guys, Have you ever tried this DSDT related fix? http://www.insanelymac.com/forum/topic/229747-snow-leopard-on-vaio-tz-tz31vn-internal-display-not-enabled/

    I guess we could use Natit.kext to inject some of the dictionary entries proposed in that link. I've been trying things for the last two weekends and I guess I learned a lot in the process. I'm convinced that we have to tack two problems in sequence. First one is to properly detect an AppleBacklightDisplay without the Nvidia driver being activated. This currently doesn't happen with GraphicsEnabler=no and until it isn't fixed we cannot go to the next step which is to force the display EDID. Also, I agree with the author of that post that GraphicsEnabler=yes somehow messes up the display detection on laptops so we should avoid using it and try to inject properties instead. I could try to patch IODisplayWrangler and IONDRVSupport classes that have source code available but it's almost impossible to do that without a second computer to debug the driver (I only have my VAIO). What could be crucial to speed up things is to find a definitive guide on how VAIO displays are supposed to be detected and then try to override the detection process in the source code of that classes. Any thoughts?

    I guess this is not news at all, but just a reminder on how the Linux guys used to fix the internal screen issue: https://code.google.com/p/vaio-f11-linux/wiki/NVIDIASetup They just have to provide an EDID dataset.
  14. Sony Vaio VPCF115FM Discussion: DSDT Injection

    Hello guys, Have you ever thought about doing something similar to this post? http://www.insanelymac.com/forum/topic/277765-mobility-5650-acer-aspire-7741g-no-lvds-qeci-1600x900-need-help-with-personality/#entry1869325 They have a similar issue with Radeon cards and LVDS. I don't have any experience with that, but thought that could give you guys some hints. If you have any new ideas, I can test them on my VPCF12M0E/B. Alexei

    Unfortunately, I don't believe that anybody is still working on this issue...
