omni Posted January 13, 2014 Share Posted January 13, 2014 If you are getting a message: X86PlatformPlugin::publishACPIStates - Failed to get max non-turbo PState. Set max non-turbo PState to default value 1 in your kernel log, add the following to your SSDT's CPU0 scope: Name (APSN, 0x0N) Where N > 0. To find N, look at your _PSS (NPSS, APSS) table and count from index 0 (top) till you reach it. For example in my case, I only have one turbo state so the next highest non-Turbo would be 1: Name (NPSS, Package (0x10) { Package (0x06) { 0x00000A29, 0x0001C138, 0x0000000A, 0x0000000A, 0x00002400, 0x00002400 }, Package (0x06) { 0x00000A28, 0x0001C138, 0x0000000A, 0x0000000A, 0x00001A00, 0x00001A00 }, Package (0x06) { 0x000009C4, 0x0001AA59, 0x0000000A, 0x0000000A, 0x00001900, 0x00001900 }, Package (0x06) { 0x00000960, 0x000193E9, 0x0000000A, 0x0000000A, 0x00001800, 0x00001800 }, ....
