OK, I checked Clover,ACPI,SSDT, Drop OEM, which seems to have done something.
Now I have this BootError regarding the Prozessor.
Here is the Clover Folder. The signature 306d4 in Screenshot seems to belong to a I7-5500. Wrong Prozessor in SSDTPRgen script?
Removed SSDT.aml: Same Error as before
Removed all SSDTs: Other Error (Screenshot)
Removed all SSDTs and DDST: Same as (Screenshot)
The i5-5257u is used in the 12,1 Family. Why wouldnt it work?
Should I try with Ma5250cBookAir7,2 (Broadwell 5250) instead?
Should I try the Remove _DSM method patch on the DDST?
To clarify. Do you mean leave Drop OEM in SSDT true and remove SSDT.aml from Sort order, when just elliminating SSDT.aml? Set to false when removing all SSDTs.
I underrstand you do not recommend touching Drop OEM_DSM, correct?
Would I need Remove _DSM method patch on the DDST instead?
I guess I have PM working. Sleep works as follows: Starts with Screen dimming. Some seconds later Screen Powers Down. About 30sec. later HD spinns down and Sleep. Wake up immediate.
