[HOW TO]modify AppleGraphicsPowerManagement.kext for X1400 of T60 in 10.6.8

18 November 2011 - 02:43 PM

I made my T60's OSX 10.6.8 work with original CPU power management, and had some other edit, including modify AppleGraphicsPowerManagement.kext .

so , it can go sleep and wake good.

but my videocard X1400 become very hot sometime, I guess it's be overclock with some wrong thing in AppleGraphicsPowerManagement.kext\Contents\Info.plist .



I edit it as below:

add code

<key>MacBookPro2,2</key> <====== I use smbios as MBP 15" 2,2
<dict>
<key>Vendor1002Device7145</key> <====== my X1400's ID is 0x71451002
<dict>
<key>QSC</key>
<dict>
<key>Enabled</key>
<integer>1</integer>
<key>Mode</key>
<integer>1</integer>
<key>hwPState</key>
<array>
<integer>0</integer>
<integer>0</integer>
<integer>0</integer>
<integer>1</integer>
<integer>1</integer>
<integer>1</integer>
<integer>1</integer>

</array>
<key>qscOnTime</key>
<array>
<integer>0</integer>
<integer>2240</integer>
<integer>3520</integer>
<integer>0</integer>
<integer>3680</integer>
<integer>4960</integer>
<integer>6720</integer>
<integer>9120</integer>
<integer>0</integer>
</array>
</dict>

<key>control-id</key>
<integer>17</integer>
<key>max-power-state</key>
<integer>8</integer> <====== 8 states as my screen light control with fn+Home(End)
</dict>
</dict>




these code are copied from the original below:

I think the main problem is those words , because MBP 8,2 use the advanced videocard.

I don't know what's the meaning of those words , and there're only information of AppleGraphicsPowerManagement.kext about N card that I can find on the Internet.



Is somebody can tell me those code's meaning, or way to make it suits to my X1400 ?

sorry for my poor English!
