I've tried to install mountain lion on my laptop vpcs12c5e (on that there is already installed os x Lion), like Lion after the boot screen of mac os the output of the display became the hdmi port, and the monitor of the laptop swich off.

This is the hardware of my pc:


CPU: DualCore Intel Core i5 540M, 2800 MHz (21 x 133)

GPU: NVIDIA GeForce 310M

Audio: Realtek ALC275 @ Intel Ibex Peak PCH - High Definition Audio Controller [b-2] PCI

nVIDIA HDMI @ nVIDIA GT218 - High Definition Audio Controller PCI

LAN: Atheros AR8131 PCI-E Gigabit Ethernet Controller (NDIS 6.20)


Lan, Bluetooth, Audio with internal microphone are working on Lion, hope they'll work also on Mountain Lion

On Lion I've got internal display working using the flag: GraphicsEnabler=No but I'm looking for a dsdt patch


Hope someone could help me


This is the DSDT extracted:

Hi there,

I have a Lenovo G460 having almost the same configuration:

Intel core i5 520m

Nvidia geforce 310m

Audio: Conexant CX20585

Wifi: Atheros AR9285


I have installed ML and everything seems to be working fine but after boot the system hangs instantly. I can move the mouse but cant access anything. You can check out my thread


Can you extract your dsdt again as I'm not able to open it.


You can see in my thread how i have edited the graphics section of my dsdt.
