Whaka Posted March 23, 2015 Share Posted March 23, 2015 Hi, on my packard bell TS44HR , i noticied the HD3000 (id 0x0126, same as early 2011 13" MBP 8,1) don't have his power management working at all. it stuck at his low frequency all time (checked with intel power gadget) someone know about this issue ? actually under 10.8.5, using MBP 8,1 smbios, with a tuned fakesmc to match the model. i have a generated ssdt for CPUPM (kp at boot if not present), and "dropSSDT=Yes"in chameleon. (nothing change on this point if i set to "No") and, is the igp powermanagement depending from the original cpu ssdt ? thanks Link to comment Share on other sites More sharing options...

Whaka Posted March 23, 2015 Author Share Posted March 23, 2015 ok... it works, with chameleon. just removing my generated ssdt form Extra, and keep only "dropSSDT=Yes" no p/c states generation by bootloader... so, fully osx native powermanagement. cpu states are ok, igp states too. and now, i really get smooth osx effects i keep MBP 8,2 smbios, but only because MBP 8,2 are 15" screen, like my laptop Link to comment Share on other sites More sharing options...
