ASUS B550F struggles with Wi-Fi during power-off and restart.
ASUS B550F struggles with Wi-Fi during power-off and restart.
TL;DR there is a known issue on ASUS B550 motherboards where they don't "wake up" devices properly from sleep, this is the only time I have issues, but when this happens, my monitor also won't display an image when coming out of sleep, even after powering off and pulling power cable from my computer and monitor. Could the MB be causing a monitor issue? Is it worth RMAing a MB for this? Short answer: It seems to be some sort of faulty HW or conflict with certain Ryzen CPUs. As one person who had a Ryzen 3000 CPU did not have issues after switching to a Ryzen 5000 Specs: OS: W10 Pro. Version 10.0.19043 Build 19043 CPU: Ryzen 5 3600 DRAM: 32 GB Corsair 3200 Mbps/MT/s with DOCP on MB: ASUS B550F Gaming WiFi GPU: AMD RX 6800 BIOS/UEFI: 2423 (Newest besides Beta) Monitor: Samsung G5 (FW 1007) Back ground: Relatively new system I built less then a year ago. About 3 months in to having it, the system would not wake properly when I took it out of sleep mode. It would vary in what stopped it, but basically it failed to POST when coming out of sleep, and my biggest weird issue is the monitor also won't show an image even when the system can POST again. Sometimes it stopped on the DIMM QLED, sometimes CPU or BOOT/drive. I thought at first this was a CPU or RAM issue, and I have RMA'd both (after extensive min conifgging) and still had the issue. I did update my BIOS several times and the CPU/DIMM POST error now does not happen, basically it halts on the BOOT QLED. I found out this is a known issue for these MBs: https://rog.asus.com/forum/showthread.ph...ssue/page2 I have the newest BIOS but it still does this even after: Updating all drivers (including GPU driver), disabling fast startup and hibernate, updating W10, running chkdsk and sfc, newest monitor FW, full min config (not a DIMM or CPU/GPU issue, only MB), disabling sleep for devices in power settings. I even RMAd my monitor, but this NEW one also goes black when this happens. You name it I have probably tried it. I have heard basically someone debugged this and the MB may not be sending voltages correctly to the NVMe drive, causing it to drop off until you do a hard reset. But the only way I get my monitor back up is by connecting a different monitor first, and then this one and it comes back to life and works fine until the sleep issue hits again. So I guess my question is, is this MB issue causing my monitor issue too? Or is it maybe a perfect storm of a faulty monitor messing up when the MB does? And is this MB worth RMA'ing at this point or should I just not use sleep? Edited December 31, 2021 by Frizz Noted answer
Based on my observations, sleep and wake cycles tend to be inconsistent across different systems. My work laptop tends to enter a very basic mode when waking, which is much easier to manage compared to other devices.
Open to testing, but I've checked my UEFI settings multiple times. If you can suggest a likely spot to revisit, that would help.
It would really impress you in my opinion if you experimented with sleep under this configuration for a month. I’m sure you’ll get a clear picture on whether the MB functions properly with specific CPUs or if certain voltage controllers or software settings need adjustment.
I could give it a shot. The last time I tried it it worked just fine, but it would wake up on its own after a short run before falling back asleep. I was bothered by it waking up without instructions, so I turned it off in the OS.
