Hi have lenovo g580.
Im trying to get Brighnetness controlls and sleep.
i have ivy bridge i5-3230M, using PNLF SB patch from Olarila i m able to get brightness control. But it requires a patched AppleACPIPlatform.kext (V1.3.6) inorder to work but to enable native powermanagement i had to use stock AppleAcpiPlatform.kext(V1.7). but with this im getting KP as 'appleacpiplatformexpert start failed '. my system wont start without 'DSDT=0'.
I hope someone can help me to fix this.
