I'm getting a 15r as well, and it has the exact same specs except for the processor which is an Intel Core i3-2310M 2,10 GHz. Will I still be able to use this DSDT?

I happen to have not the i3 or i7 models, but the one in the middle, the i5 model!




So is someone able to make a DSDT for the i5 and complete the DSDT collection for this laptop model?

First, I want to thank everyone who helped (androdev, MaLd0n,...) to be able install the Lion.

But I can not solve the problem of the touchpad.

I installed the kexts (AppleACPIPS2Nub.kext, VoodooPS2Controller.kext) in S / L / E, but does not work on 32bit or 64bit.

Is it necessary to change the DSDL file?

I appreciate any help.

Thanks MaLd0n,


Just applied your fixed dsdt, system can go to sleep - power light flashing slowly and fan turn off... but system still cannot return from sleep... After pushing the power button, I can hear DVD reading, power light turn solid but screen is blank and cannot ssh logon. I am on Lion GM and com.apple.Boot.plist modified as suggested:











<key>Kernel Flags</key>


<key>Legacy Logo</key>






Kexts in /Extra/Extenstions:






Additional Kexts in /S/L/E:



AppleACPIPlatform.kext (replaced by the vesion from 10.6.7 to get VoodooBattery to work)


apart from the above all are vanilla kexts.


Attached below with send_me.zip stuff captured before/after applying the fixed for your reference:

send_me_Old.zip ---> Before apply your fixed DSDT

send_me_New.zip ---> After apply your fixed DSDT


BTW, how can I verify Speedstep is working or not?
