Aloha !

I have been quietly following this thread for a while and have found it extremely helpful AND educational. I now have a closely related HP notebook with most everything working ... only one last hurdle. The CPU fan stops and never runs again after waking from sleep. I understand that I need ACPIThermal.kext installed and that there are some DSDT mods involved as well. The DSDT mods are where I am having an issue as my DSDT is a bit different in the TZ scope area than the ones in use here.

Here are some of my system details ...

Notebook: HP 6910p
Chipset: GM965
CPU: T7700 (merom)
GPU: Intel x3100
O/S: Mac OS X 10.6.8

I have rolled the SSDT data into the TZ area of the DSDT but can't seem to figure out how to proceed further as a couple of my critical internal data structures differ a fair bit from your example DSDT.

Perhaps someone can explain in words what exactly is being changed in the TZ scope ?

I've attached my TZ scope for reference ... (I've transferred like comments from your DSDT to make cross-referencing a bit less painful)

Any help or advice from you resident gurus would be most appreciated :)

I'm not sure if this can be useful but I was able to make the external vga of the hp6720s fully functional, you just have to connect the vga when the pc is off, then turn it on and close the lid, the system wil load normally and once loaded you can open the lid and use the external monitor (the internal will be turned off)
I'm running snow leopard 10.6.6 and my gma reference is x3100 2a02 I'm going to do some further testing... (note that before my vga plug wasn't working, even if mirroring was turned off the screen was scrambled the "usual way") I hope this was useful

So, you don't need to be "expert" to implement THIS WAY (new DSDT + SSDTs + org.chameleon.Boot.plist + smbios.plist + Kexts).

Unfortunately, I can not test right now - I've already sold this laptop (switched to MBP), but I will ask new owner to test this...

Hi juanerson, I've borrowed HP 550 laptop from my daughter again and installed Lion using your files just to check and, eventually, help testing C_states issue. Great work my friend. Smooth install everything working just like on Snow Leopard.
About c_states:
Boot info screen states that C_states implementation failed. Collbook shows normal speedster working. Here is my ioreg File:
http://dl.dropbox.co...s%20MacBook.zip
P.S.
Seems that HP 550 run hotter. 74 C on harder tasks or maybe Istat menus (free version) shows higher results. I remember blackch had a solution on this but It was long ago I was using this laptop and forgot almost everything about it.
EDIT:
Occasionally freezing (screen, not mouse) using Thirdsmile patched kexts (Brightness fix)

Brightness patch for 10.5.8 Framebuffer kext(from here) - same as for 10.6 and 10.7.
Do not know if it is needed in fact, but even so I made it...
Also I have not tested it, but I think it should work.

Hi Thirdsmile.
Are you experiencing some screen freezing with your graphic kexts? (screen saver, sleep etc)

Last time I have used 10.7.2 with framebuffer from 10.6.8 - and there was no freezing.
From that time I have switched to MBP, so now I can not test how latest versions work.

No more problem with audio stuttering here. Maybe it was a cache problem. Now i have problem with graphics freeze, when i watch a video on youtube my screen freeze. I've tried to install thirdsmile GMAX3100FB patched but i have a black screen on boot (i've also overrided EDID). My card is 2a12.

Have you patched it for 2a12 (patched kext above is for 2a02)?

smilenkovski,
Corrupted file again, maybe due to Xcode version. Please use the .app attached to extract. Thanks my friend.
iStat Pro widget for temperatures. And please do not upgrade it, is a hacked version by Slice.

alemate23, Which SSDT tables (for C-States) are you using for Merom? Because smilenkovski have NOT C-States (Merom too) support from his ioreg.
Can you upload your ioreg, Please? Private Message.

smilenkovski, from your ioreg (was extracted before the EDIT part, right?):
You need C-States for better temperatures and prevent audio stuttering.

Also, why don't have installed the proper FrameBuffer? from 10.5.8 patched by ThirdSmile HERE... or the vanilla one I uploaded HERE... that FB.kext avoid the KP "GPU parser error...".

All the rest is fine... SpeedStep, fan control, battery meter...etc.
