Windows 10 Pro no longer supports sleep functionality.
Windows 10 Pro no longer supports sleep functionality.
I have installed Windows 10 Pro Version 21H1 on the 11/11/2020 OS build 19043.1110. I’m using Experience Windows Feature Experience Pack 120.2212.3530.0 with hardware like the Asus X470 Gaming F AMD 2700X, 32GB RAM, Vega56, and storage devices ranging from 500GB to 860GB. I recently adjusted power settings via Settings > Power and Sleep, but now only the monitor sleep timer remains. Previously, I had a second entry to set the PC sleep timer as well. I explored registry changes and found the driver for my Vega graphics card was installed correctly. I restarted after each attempt. Before noticing the problem, I applied several Windows updates, turned off PBO, lowered core and LLC voltages, and reduced the number of active cores from 8 to 4 due to heat concerns. I’m unsure what should come next.
Sleep features are turned off when there is one device connected that doesn’t allow sleep. This might happen if a driver is missing. Open Device Manager and verify all hardware is recognized (Chipset, GPU, Audio, Ethernet, Wireless, Bluetooth, SATA Controller, etc.). Ensure no "!" symbols appear anywhere.
Other than that, I’ll look again for anything. The only new items are a card reader and a Razer Basilisk basic mouse. The mouse software isn’t running, and there’s no indication of sleep being disabled anywhere. Even with advanced power settings, the only option is hibernate.
Powercfg command executed on the specified path. Available sleep options include Hibernate. Not supported states are Standby (S1), Standby (S2), Standby (S3), and Hybrid Sleep Standby. Standby (S0 Low Power Idle) is also unavailable. Fast Startup feature is currently disabled.
The setup matches the expected configuration. S3 and S4 are activated as required.
I located a configuration for S4 and S5, but not S3. I’ll go through my manual to understand it better. This BIOS is quite annoying because adjusting one setting often affects many others, such as resetting RAM speed, voltage, and timing when I change CPU OC options (manual, auto, DOCP, default). It also impacts sleep functionality. I managed to get it to hibernate, so that’s one thing. Wake-up is slower but power consumption is lower, though it might stress the disk.
I updated my BIOS to version 5809 from 5406, which led me to the latest AGESA for my X470 board. It introduced finer CPU controls, a resizable BAR, enhanced memory settings, and more options to experiment with. This change made my PC unstable at first, but I managed to get it stable at 90W @3.7Ghz across all eight cores, which suits my daily tasks well. The new BIOS settings also clarified something I hadn’t noticed before: disabling CPU cores would turn off S3 sleep mode. This wasn’t mentioned in the manual, BIOS docs, or online forums—so this was my solution.
This feedback is really helpful! It’s frustrating seeing manufacturers overlook important details like BIOS settings. The BLCK value option should have been clearer in the manual. I’d appreciate it if companies prioritized better documentation and clearer explanations for consumers. While I’m knowledgeable, I sometimes struggle to keep up with rapid changes in CPU architecture, and having more detailed guidance would be a big plus. Thank you for uncovering this issue and helping others avoid unnecessary troubles.
I'm glad this assists others. My previous challenges with 4th gen Intel 80 series boards and Asus BIOS updates have benefited many people. It's great that the Asus Ctrl-C/Ctrl-V feature from AMD documentation fits into the BIOS context boxes. The UEFI is particularly helpful since it's tailored to your board and current setup, unlike searching online to verify compatibility. It only requires minimal space for context text, which is helpful for the X470 board with its larger ROM chip.
