DSDT Patching for DELL Sandy Bridge Processors

Recommended Posts


Hi, i have one Dell N4110 laptop, the specs is :

CPU: i5 2450

GPU: HD3000+AMD6630m

LAN: Realtek 8136

Wireless: Intel-n 1030

Audio: ALC269-vb

Extra: Synaptics touchpad, realtek card reader etc.


By now, i get most of them working, except the hybrid GPU, and i see a topic about this, by using dsdt & ssdt to disable the discrete graphics, only use the integrate one. Also i try to do it, but can't compile the ssdt part into dsdt. I am wondering whether you can do it.

Here is the link: http://www.projectosx.com/forum/index.php?showtopic=2315&st=0 The author have Intel+Nvidia optimus, and he succeed disable the Gt5xxm, but in my case, it seems that it doesn't match Intel+AMD combination.

nvidia optimus and amd dynamic switching are two completely different approaches and cant be disabled by a dsdt.
