B560M AORUS ELITE - Doesn't wake up from sleep mode

[Modigliani]

I've tried a number of things to try to resolve this, but I still haven't been able to isolate the problem.

I have this motherboard: B560M AORUS ELITE.
 

A few months ago, my computer started having issues waking from sleep mode.

I updated the BIOS this week to try to resolve the issue again, switching to F12 (latest version). For four days, the computer couldn’t fully shut down – it kept the monitor light on, and pressing the power button didn’t turn it back on. To shut it down, I had to unplug it, wait 5 seconds, plug it back in, and then it would turn on.

After four days with the updated BIOS, it started shutting down normally. I knew it was shutting down correctly because the monitor light would blink, and when it shut down “incorrectly,” the light would stay on.

Once it started shutting down normally, I tried putting it to sleep, and it worked perfectly. For days, it went in and out of sleep mode without issues. Then, I needed to move the computer to the living room, so I shut it down, plugged it in in the living room, and it turned on normally. After leaving it idle for a while, it went to sleep but didn’t wake up, and I had to unplug it again.

Then I brought it back to the office, put it to sleep, and it wouldn’t wake up. I booted into Windows, and it still couldn’t wake from sleep mode. No BIOS settings were changed during this transition.

What I've tested so far:

• Replacing the power supply
• Swapping the RAM
• Disabling XMP
• Replacing the GPU
• Shorting pins 5 and 6 on the GPU
• Booting without the GPU
• Testing sleep mode wake-up in Windows
• Enabling and disabling the ERP option in the BIOS
• Restoring the BIOS to default settings
• Booting direct from windows boot loader

I would love to have sleep mode working again, but since the issue also happens in Windows, I believe it may be related to the BIOS settings or a hardware issue.

Is there anything I can try configuring in the BIOS to see if it can wake from sleep mode and keep working?

Hi MaLd0n, I tried this too, and I even added this link to my description. It seems to me that the problem is in the hardware. When updating the BIOS, for example, the computer turns off and on by itself. In my case, when it turns off after starting the BIOS update process, it can't turn on to continue the next steps of the update. I need to unplug it from the power outlet, turn it on, and then it continues updating the BIOS, but every time it turns off during the BIOS update, I have to do this again.

But the strange thing is that within a few days it can go back to sleep normally. Do you have any idea how I could find out where the problem is?

It all started after I did a BIOS update, but even reverting the BIOS to that old version, the system didn't come back.
