x99 instant wake

[irix78]

Hello,

 

My build:

Main Board: Huanan X99-tf (UEFI BOOT)

CPU: XEON E5-2678v3

RAM 4x16GB DDR3

OS: 10.15.5

 

Everything works perfect except sleep/wake.

It go to sleep without any problem but after 1-2 sec it wakes without any reason.

 

Most strange is that pmset -g log shows NO wake reason.

 

Wake from Normal Sleep [CDNVA] : due to / Using AC (Charge:0%)

Kernel log shows:

Wake reason: ?

 

I have tried all suggestions I have found including SSDT-UAIC, Energy Saver settings, hibernatemode change, different bios settings but nothing.

 

Any suggestions?

 

Regards

Piotr

for my case, it has something to do with the usb, i need to set usbconnector to 255 (internal) or 0xFF.

i was using corsair aio cooler, and i set the usb for my corsair cooler to internal if i plugged in the usb connector of corsair to motherboard.

for now i am using BCM943602CS and i set the usb connector to internal for the bluetooth (usb header connected to mobo)

 

if you have devices with usb header connected directly to the motherboard, i suggest you need to set it to 255

Thank you for the suggestion.

 

Problem SOLVED!!!

1.Surprisingly turning "Enable Hibernation" to DISABLE in BIOS fixed sleep issue.

It sleeps ok but did not wake from keyboard/mouse but power button only.

 

2. I have found hidden JPWR switch under rear ports cover, and enable usb power when sleep.

It did not help immediately so i have to RE-ENABLE "Enable Hibernation”  and it works perfect now.

Thanks for any help!
