I tried to install GenericUSBXHCI with and without serval options.

GenericUSBXHCI was loaded normally but no effect to sleep function.

 

When I close lid or choose 'sleep' from menu, LED(on Powerbutton) starts blinking and Fan stop.

When I open lid or type keyboard, Fan starts spin up but LED is still blinking and Display stays on black. 

And I can't find any words related to sleep/wake on system.log.

If you are using and voodoosd card driver, remove it, it has that effect.

VooDooSDHC(with and without mod) is nothing to effect on my system. So I already removed.

 

To modify VooDooSDHC,

I need to edit only vender,device ID on IOmatchname section on info.plist of VoodooSDHC. is it right?

you can check in chameleon wizard app the option to enable backlight and see if that works.

I try it but no effect.

I think enablebacklight option is for ATI and nVidia GPU.

My laptop has nVidia GT 730M but 730M doesn't work.

works with only Intel HD4400. can't boot without option SkipNvidiaGFX=y

Display Sleep, Brightness and Dim are working after patch DSDT.

 

I also tried wake on LAN. Ethernet port LED is active on sleep but nothing will happen.

 

I think I have to patch DSDT for wakeup from sleep funtion.
