DSDT for Lenovo W520 model 4270cto

[陈小龙]

Could someone kindly patch the DSDT for my Lenovo W520?

 

Currently, the following functions do not work:

 

Sleep/Suspend

Brightness control (nVidia Quadro 2000m)

Battery (not detected)

Audio (Conexant 20672 SmartAudio HD)

 

Is it possible to fix these with a patched DSDT?

 

Thanks in advance!

 

EDIT: Additional information:

 

In /Extra/org.chameleon.Boot.plist, I have

 

<key>GeneratePStates</key>
<string>Yes</string>
<key>GenerateCStates</key>
<string>Yes</string>

 

SMBios: MacBookPro8,1 because I have a Sandy Bridge laptop.
