FireROR Posted January 20, 2013 Share Posted January 20, 2013 Hello I recently install the iatkos ml2 on my Thinkpad T520 and everything work OOB including the HD3000 video card. And yes. I do replace the WIFI card and flash the whitelist BIOS (1.39) And I created a DSDT file try to get the sleep working on my Thinkpad. The system boots ok then screen goes weird (like the resolution is not right or something, some bright like cross the LCD screen). The keyboard still responds which make me believe the system is ok. I tried use GraphicsEnabler=No and it still the same. Any help? System info: Thinkpad T520 4239CTO Resolution: 1366x768 Link to comment Share on other sites More sharing options...

FireROR Posted January 20, 2013 Author Share Posted January 20, 2013 Mine is 0x01268086 which I think it already in the info.plist. And the qe/ci is enabled without DSDT file. I did copy some settings from the T420 DSDT file which is about the HD3000. Their T420 is on HD+ screen but mine is 1366x768. Is that matter? I am not familiar with DSDT edit, could someone help me?

Yes. Try adding/editing this: "AAPL00,DualLink", Buffer (0x04) { 0x00, 0x00, 0x00, 0x00 }, inside Device (VID) 1 Link to comment Share on other sites More sharing options...

Thank you guys... This values are internal screen specific taken from real Macs. Simply enables or disables dual link. For low resolution screen (or none if I remember correctly): "AAPL00,DualLink", Buffer (0x04) { 0x00, 0x00, 0x00, 0x00 And high resolution screen (1440x900 and higher): "AAPL00,DualLink", Buffer (0x04) { 0x01, 0x00, 0x00, 0x00 Link to comment Share on other sites More sharing options...
