Help with Ati Mobility 4650 (id:9480) on HP DV7 17"

hi to all,

 

i'm on Snow 10.6.8 ...and i'm been crazy ! :)

 

I read all the posts but i can't reach a good result. The HDMI output works at full resolution, but the internal LCD 17" is black ... i try ATY_init, GraphicsEnabler=Yes/No, video ROM ... nothing.

 

I don't understand this:

 

1) what is the connectorinfo ? Where can i edit it ?

2) what's the right method: bootloader with GraphicsEnabler, Kexts, video rom, ecc ?

 

Thanks !

Hi. I got the same laptop with the same Graphics Card.As of now I've gotten so far as having internal screen working at full resolution with acceleration, but output is corrupted (on 10.6.6). When using 10.6.8 the colors are wrong too. Pay a visit to muchas thread here in the ATI section. He has posted a very good tutorial. You also need dual-link patch in DSDT. If you tell me your exact model of your laptop and its the same as mine (DV7-2160eg) I can send you my DSDT file). Also, be advised that when following much as guide you will likely get LVDS connector info that ends with 12 00 00 07. For me it was like that, but in the end it wasn't working. I had to change it to end with 12 01 00 07 in order to get output on internal screen.

Hi Drake :)

 

My Laptop is DV7-2215el (http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01959180&tmp_task=prodinfoCategory&cc=it&dlc=it&lc=it&product=4050124)

 

I read all the avaiable guides ... but maybe i don't understand the correct procedure.

 

Now i'm in Lion and I try:

 

- Edit plist in ATI4600Controller to add my card: 94801002

- Edit bin of ATI4600Controller insert Shrike buffer with the personality found by misha (http://www.insanelymac.com/forum/index.php?showtopic=252061&st=256)

- Boot with Chamaleon (Shrike-Peregrine) and GE=YES/GE=No

- Patch DSDT to add DualLink

 

Nothing ... i have enable the remote desktop so i can connect and see screen only by VNC... and i see that the grafiphic card not recognized :(

 

Can u explain me your steps please ? :)

Hi Drake,

 

my best result is:

 

- Edit plist in ATI4600Controller to add my card: 94801002

- Edit bin of ATI4600Controller insert Shrike buffer with the personality

02 00 00 00 40 00 00 00 09 01 00 00 12 01 00 07 for LVDS

- Boot with Chameleon Shrike GE=Yes

 

LVDS is on but i see a noise (as a old TV without signal) and the image ed colors are scrambled. Override EDID ... no changes :( ... i think that there aren't other chances :(

May be the problem is the dual lvds interface as touched in this forum (about other matter):http://forums.guru3d.com/showthread.php?p=3789313

I think so because my panel is a lg and present the very same problem as your: I can´t get lvds. Seems that it show half resolution and not the expected image. Btw, my card (4650 mobility) uses dig 5. Very strange.
