Hi all,
As most of you who own a Dell XPS 9500 know, its ACPI S3 sleep is broken (and the 9510, 9520 and new 9530 didn't fare much better). After some work on this loaned machine, I've finally managed to create a fully working hibernate (mode 25) and resume for the XPS 95x0 family, which works quickly and consistently, and importantly is a much more practical solution for a hackintosh than shutdown.
Latest EFI snapshot can be found here
The only issue I have at the moment is that upon resume from hibernation there seems to be some form of additional power drain (not due to any OS process load as far as I can see), and the temperature increases by about 10C which suggests some kext and/or device is not behaving properly. I've attached the powermetrics for pre- and post- hibernation, alongside a power gadget screenshot (you can see where the suspend/resume event is from the temperature hike).
Any suggestions/tips as to what could be happening here?
Thanks in advance
