Techmaniaco Posted May 25, 2014 Share Posted May 25, 2014 I've gotten pretty much everything to work on this y510p ideapad hackintosh I've made.Everything except the brightness controls. For some reason, I can't change the screen brightness while booted into Mavericks.Anyone have a solution to this? Quote Link to comment Share on other sites More sharing options...
Techmaniaco Posted May 25, 2014 Author Share Posted May 25, 2014 I also have problems with the usb ports. When I plug in a usb device while booted into Mavericks, the laptop freezes after a few seconds within plugging in the usb. Is this a problem with the IO storage controller?

Arise Posted May 25, 2014 Share Posted May 25, 2014 You should add a kext to let your fn keys interpret brightness , you need ACPI functions/methods in your DSDT and also you need to inject an efi string probably to get that working.If you look in preferences under display, do you have a slider to adjust the brightness?Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
Techmaniaco Posted May 25, 2014 Author Share Posted May 25, 2014 I tried downloading an ACPI kext for my exact laptop model from insanelymac, and that fixed my sound adjustment issue with the keyboard, but not the brightness adjustment. There is no brightness slider under display, and the monitor has one resolution to pick from, which is the one I forced. I am not using a DSDT. Is that why I cannot find a solution to this?

Arise Posted May 26, 2014 Share Posted May 26, 2014 Yes, you need DSDT methods to read and set screen brightness, but those alone won't work without efi string I guess in your case.So, besides Q0E and Q0F methods or PNLF device, you need to inject the efi string of your video card.Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
Techmaniaco Posted June 12, 2014 Author Share Posted June 12, 2014 I tried editing the DSDT of my system, but it turns out I can't use it because it's so screwed up. There are so many errors returned by MaciASL when compiling it unmodified. Quote Link to comment Share on other sites More sharing options...
ka05th30ry Posted June 12, 2014 Share Posted June 12, 2014 Techmaniaco,you can set the screen resolution by adding the following lines to your /Extra/org.chameleon.Boot.plist <key>GraphicsEnabler</key><string>Yes</string><key>IntelAzulFB</key><string>12</string><key>Graphics Mode</key><string>1366x748x32</string>This worked for me.As for the brightness,I havent figured that out quite yet either. Please let me know when you figure it out.Thanks Quote Link to comment Share on other sites More sharing options...
