Cannot wake from Hybrid sleep

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hi everyone

Recently I noticed that I cannot wake my PC from sleep: When put to sleep, the fans stopped, and RAM is still on (at least their LEDs are on). When you try to wake it up, the fans spin up, PCH LEDs turn on, then after a second or two the power just got completely cut off. After that you have to press the power button and go through POST to enter into Windows. The last Dr. Debug code before everything goes off was E3, according to this post it only indicates that system is waking from E3 state, not sure if Asrock use the same list though.
After some troubleshooting I found this seems to be related to Windows's hybrid sleep feature. For those who don't know, hybrid sleep is a combination of normal sleep and hibernate where the system is suspended to RAM (normal sleep) and a copy is also written to hard drive. The idea is that you can still quickly resume from RAM but also protected from power loss or such with a non-volatile copy.

So in short I found out that if I turn off hybrid sleep the system could wake up normally from sleep. I think this works OK but I still want that hybrid sleep for being protected from power failures or such. And this is really strange as waking from hybrid sleep should be exactly the same as waking from normal as long as everything was still in RAM. I tried to look into event logs but couldn't find anything though. Dose anyone have any idea on this?

Here is my setup

Mobo: Z370 Taichi
BIOS: P1.80. Had tried to load default setting but didn't help.
CPU: i7-8700k, no OC
RAM: Corsair vengeance RGB 8G*2. Had tired to revert to 2133MHz base clock and problem still persists, so shouldn't be related to RAM OC
No discrete GPU (yet).
SSD: Samsung 970 EVO 1TB
PSU: Corsair HX1000 Platinum
OS: Win 10 build 1803, latest update and latest drivers.

	So I finally got some time to test this. put in a new SATA SSD and install win10, it can do hybrid sleep and wake up correctly. So this is related to either my windows settings or NVME driver.
