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 :)

ok :)

 

i already tried with MBP 8,2, and i'ts not better...

i'm going to test with MBP 8,3 and i tell you

 

edit : tried with MBP 8,3, not better,  and with mac mini 5,1 screen freeze before login screen.

i'm going to try clover, maybe he can do the trick.

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 :D
