chofete Posted June 16, 2011 Share Posted June 16, 2011 Hello I have a hackintoshed HP 8540w, it´s almost working 90%. One of the things that it´s not working is the brighnest level control. If i start with AC connected it works a full brightness. If i start without AC connected it works al low brightness level. The graphic card is a nVidia FX Quadro 880m. If i open Screen Preferences i saw a Brightness bar under screen resolution, i touch it but it´s locked (can move but always return to the same place). I can press keys to change the brightness but alwasy at same level. I found a thread talking about it: http://www.insanelymac.com/forum/index.php?showtopic=220057 I tryed to write it on the dsdt.aml i use, but i can´t compile it. I attach the dsdt.aml with the correction: dsdt.zip I attach the original one too: dsdtoriginal.aml.zip If anyone can help me he is helping other people too. Thanks to everyone.
