​

This laptop has i5-10210u with CPUID of A0660 which isn't supported by XNU. After seeing EB|EXITBS:START screen for more than hundred times, I found out that I have to spoof it as 806EC.. hard start 😅

It took me A LOT of time to fix lidwake, hibernation.. :D

​

For waking the machine up with lifting lid while it's on S3 sleep, I had to put _PRW method to _SB.PCI0.LPCB.H_EC device & make patch for OSYS and GOST to make it recognized as Windows10.

​

For hibernation, adding HibernationFixup.kext&setting Hibernatemode to NVRAM&enabling `Fix black screen on wake from hibernation for Lenovo Thinkpad T490` patch on ReservedMemory from Sample.plist did the job.

​

Also, when disabling NVMe drives, use SSDT-RP01.PXSX-disbale from OCLT. Using one from dortania caused package power to get higher after sleep.
