Asus Prime X299-A won't wake up from sleep mode

[czmiho]

Rig: Asus Prime X299-A (BIOS 0802), i9-7960X, 2x Corsair 32GB KIT DDR4 2666MHz CL16 Vengeance, Corsair RM850X, ASUS ROG STRIX GAMING GeForce GTX 1080Ti, 2x Samsung 960 EVO 500GB, Clean windows 10 install, all drivers current. Hibernation disabled.

Problem: PC doesn't wake up from sleep When I press power button it seems that it is waking up but i think that it reset in the process - after 2-3 seconds fans go louder like in cold boot.

Tried so far: clear CMOS, load optimized defaults, playing with some settings in BIOS (like ErP, PCIe speed,... ), windows with and without samsung nvme driver, with and without intel storage driver, 2 latest nvidia drivers, different GC. Different PSU and cables (same model). Reinstall windows.

It behaves the same in live ubuntu 17.10 (beta). Suspend in Linux on new platforms is iffy (+ suspending while booted from USB is not recomended i guess 😉 ) so i don't take it too seriously.

Hibernation is working but it ist too slow for me. It also hammers SSD (with 64GB of RAM)

Another clue: when i enable BIOS option RGB LED "when system is in sleep, hibernate or soft off" - then it goes off anyway when i put computer to sleep.

I am now out of ideas how to fix it 😞

Thanks in advance

There is latest firmware on both nvme SSDs. I don't use magician (i don't like unecessery software in my system). I would try with no nvme SSD but what's the point, i need them both.

I've tested sleep in linux (full instalation) and it behaves exactly the same.

I give up. Maybe next BIOS will fix it (small chance) otherwise i will just leave PC on all the time 😉

Two questions, one did you get this issue resolved? Two, did the PC ever sleep correctly before this issue happened?

I ask because an X299-E STRIX setup I worked on recently developed a similar issue. It was sleeping fine for a few weeks.

Edit: Nevermind, corrected the issue by removing the battery and putting it back.
