Lenovo U410 few little issues

Recommended Posts

Hi,

 

I recently bought myself a nice little Lenovo U410

 

Specs:

- CPU type Intel Core i3 3217U (Ivy Bridge)

- CPU speed 1700 Mhz

- Graphics HD400/Nvidia GeForce 610M nvidia optimus

- RAM 8GB, 500GB HD, 24GB SSD

- Sound: 7 Series/C210 Series Chipset Family PCI Express High Definition Audio Controller (8086:1e20)

- LAN Realtek RTL8101E/RTL8102E (10ec:8136)

- Wifi: Some intel centrino chipset -> to be replaced

- Card reader

- 2x USB3 port (8086:1e31)

- 2x USB2 port

- Webcam

- Synaptic touchpad

 

As I understand, I dont need to care about the GeForce Optimus Card.

 

I did a ##### install using the Fusion guide and osx is running pretty stable. I had do do some patches in DSDT to get sleep working -> needed to patch UHCI to step down the (not working) USB3 ports to USB2 standards.

I needed to remove the XHCI kext from IOUSBFamily.kext to get the webcam working.

 

Some things are still bugging me:

- Is there a way to get my audio working without voodoohda? its working, but I cant autoswitch between earphone jack and internal speakers. Right now, I have to switch die output device thru system settings.

 

- brightness control is working, but I'd like to patch DSDT to set the control to a few steps. Right now, I dont see the OSD when I change brightness thru fn keys and since this Ultrabook has numerous steps between full and lowest brightness, it takes almost 20 secs to get from one end to the other.

 

- Cant get the ethernet to show up in system settings...

 

Other than that this little thing is awesome...

 

Cheers,

Mike

Ok, got Ethernet to show up in System Preferences...

 

I installed Apple8169Ethernet.kext and voila, Ethernet is showing up. Now I have access to App Store. Don´t know if Ethernet is actually working, but since I use wifi only, I don´t care :-)

 

OSD for brightness control left to be fixed

Hi,

 

made my audio device show up in System Information.

 

I still get some errors while booting, so I still dont have audio thru applehda.kext. But I'm getting closer somehow :-)
