Problem with sleep function on Windows while using a dGPU
Problem with sleep function on Windows while using a dGPU
Hello I have this PC running Windows 11 pro* and most recent updates for every installed apps. It is configured for not going to sleep ever (only the display turns off after 1h). CPU: i5 9600K MB: Asus Z390-A (latest BIOS v.2004) (GPU: Rx590 using HDMI) SSD: 250GB Samsung 750 evo (sATA 2.5'') RAM: 2x8GB DDR4 2666 PSU: XFX XPS 600W Monitor: some Acer FHD monnitor (using HDMI) When using only the iGPU (no dGPU installed), everything works as expected. Whenever I install my dGPU (XFX RX590), the PC will go into some kind of sleep state after a while. You could say it "plays dead" It becomes unresponsive (won't wake when moving the mouse or using the keyboard) and can no longer be reached remotely (using some kind of VNC-like). The RGB lightning seem to indicate that the PC is still ON though. Only a hard reboot will allow to get back to windows. I tried swapping the dGPU for another unit of the same model that works well in another PC. The problem remains with this PC (meaning the dGPU unit seems OK). If this is a settings issue, I cannot find what setting I need to change. If this is some compatibility issue, I don't know how to troubleshoot it. Do you have any advice for me? Thank you very much in advance for your help. Best, -a- (* I had the same issue when running Win10pro. I recently upgraded to Win11 to see if it would fix the issue. It didn't)
Thank you for the details. I disabled sleep modes, hibernation, and hybrid sleep. Also, I’m confused about why the issue appears with a dGPU but not an iGPU when the problem seems linked to the PSU. Could it be that the PSU isn’t powerful enough, or maybe the power supply doesn’t meet the requirements when the dGPU is off? The PC keeps running without shutdown, including fans and RGB, even during idle times...
I also misinterpreted the topic. The link provided explained Windows power states. Let me know if you need further clarification.
