Hello. I know, that currently it is impossible to get sleep/wake functionality using just Intel HD530 and HD630 Graphics cards. I would like to gather as much of knowledge of this problem as possible, so please share all you know / think about this. Also if something Im writing is wrong, please correct me. Maybe it would somehow be possible to overcome this. I know chances are low, but I would love to try. So here's what I know:
- Problem occurs when we use systems with only iGPU and no discrete GPU installed.
- It is causing the system not being able to wake from sleep. Usually it's first a black screen, and after a few seconds crash/reboot.
- Its occurring on Intel Integra HD530 and HD630, so in CPU's like Skylake, Kaby Lake. Im having it on i7-7700T.
- Problem does NOT occur with UHD630 for example on Coffee Lake. Sometimes there is a little confusion because of that, because people tend to confuse these two GPUs.
- It has something to do with wrong implementation of _WAK function in SSDT (please write more about this if you know).
- Using hibernate mode 25 doesn't resolve this, because resuming system from this also uses _WAK function.
Currently only solution is to install secondary - discrete GPU. But I would like to have a compact design PC, and fitting separate GPU is not a option in that case.
Do you know what part of OS is causing this problem? Do you think it might be possible to solve with some software hack?
Would it be possible to resolve this by WhateverGreen developers?
Please share all you can think of, like where to look, what to research, and so on. I know there is a small chance of success, but still I would like try.
