System didn't enter sleep or hibernate mode correctly.
Type "Make sure that standby and hibernate are present." into PowerShell.
Hi @Eragonvn Have you identified the issue? I'm experiencing a very similar problem now. The main change was switching to a new GPU—from 3070 to 6950XT. After installing Windows 11 and setting up the system normally, I can put it to sleep. However, every few times I do it, it seems to attempt the shutdown but fails. The keyboard, mouse, monitors, case fans, and power button stop working, yet the GPU lights remain on. It doesn't enter a full sleep state. Usually, the PSU makes a click when it powers down, but during these unsuccessful attempts, it doesn't occur. The computer won't wake up even with button presses or a power button click—it just keeps blinking. A reset button also doesn't help. The only way to restart is by holding the power button to shut it off manually, then pressing it again and booting into Windows normally.
