[Guide] HP G62 DSDT working with SpeedStep

[Sainath]

Hi guys,

i wanted to share with you the dsdt i created from my HP G62-363TX,but should work with any intel i3 370m HP G62 laptop. I will also attach only the patches to apply it to your dsdt if your specs are different.

 

My system specs :-

CPU - i3-370m

GPU - ATI 5470m

WIFI - Ralink 3090 ( doesn't work )

 

Heres whats working :

1. SpeedStep( Enable P&C state & also C2 , C3 , C4 state ) Use SSDT from update 1 and DropSSDT=Yes
2. Battery ( Use AppleSmartBatteryManager.kext )
3. All USB ports
4. And all major DSDT patches

How to Use :

 

    Using DSDT :

                          Copy to /Extra and add DSDT=Yes to boot loader or check select location of dsdt.aml  in Chameleon Wizard

    Using Patch :

                          Use Chameleon Wizard 

                             1.  Go to DSDT

                             2.  Select patch Tab

                             3.  Under apply patch choose the respective file and patch 

                             4.  Then add DSDT to bootloader

   Patch your own DSDT :

                          Use any DSDT editor and add patch. Simple. REQUIRES A CLEAN DSDT. MAY GIVE ERRORS FOR PRE EDITED DSDT.

Enjoy ! 

Happy Hack !

Update 1 :-

Use SMBios as MacBookPro 6,2

• Graphics Card enabled thought DSDT ( ATI 5470M ) -

                                    Use GraphicsEnabler=Yes

                                     and vanilla kext

• Use SSDT attached to get SpeedStep without P&C-states

                                    To use ssdt boot DropSSDT=Yes

• Minor patches

if it doesn't work use the first DSDT and SSDT from the update 1

if doesn't work patch your own DSDT check update 2.

Update 2 :-

 

Added Text files containing the patches. Try both any one will work. REQUIRES A CLEAN DSDT. MAY GIVE ERRORS FOR PRE EDITED DSDT.

1. G62 350m
2. G62 370m

To use the text files use any dsdt editor and select add patch and choose the text file

 

Also added SSDT.aml separately.

Hi. How did you patch the SSDT? What patch did you use?

[Sainath]

The ssdt.aml I extracted from windows. I also patched power management in dsdt to get 7 states. Power management works even without ssdt.aml

[Sainath]

Btw did the dsdt work for you ? Im the speedstep ?

I recently modified the bios disabling Intel HD Graphics. I've installed OS X Mavericks this morning. Let me some time and I'll test it.

[Sainath]

sure !

Update :

add the patches as text file and SSDT separately.

[giofrida]

I applied the 'i3 350m' patch in my DSDT (just the _INI method patch, because I've already applied the other ones) but I don't find any improvement.

 

Are you using Clover in order to get HD 5470M to work? I'm using it with patched connector values but VGA doesn't work (yet)

[Sainath]

I used to use chameleon (internal display only) recently I shifted to clover (internal display and HDMI) didnt test VGA ! Test if your power management works (p-state)

[giofrida]

Have you got an application or kext to check C and P states?
Another question, are you using AppleHDA for the sound? Does the internal microphone and HDMI audio work?

 

EDIT: I tried the microphone on Windows and it doesn't work at all. So it's not an AppleHDA problem. Please try your microphone and tell me if it works or not. Thanks

[Sainath]

Microphone didn't for me on hackintosh. Use can test p-states with DPCImanager. Didn't try HDMI audio yet.

I've just found out that my microphone needs to be replaced. 

 

With your DSDT edit:

P States: 7, 8, 9, 12, 14, 16, 17

 

Without:

P States: 7, 8, 9, 12, 14, 16, 17

 

It seems that adding the OSI Darwin check does nothing (maybe only lower temperature, maybe)
