The elegant solution is not just written for energy efficiency under Windows 11/10. As you can see from the screenshot taken in Windows 10 above, it is quite easy to influence the computer depending on the CPU load. You can easily use this simple and fast CPU load-based hibernate solution on older versions of Microsoft's Windows operating systems, whether it's a Windows desktop, tablet, Surface Pro / Go, or even a server operating system.
I discovered that Dontsleep works if you also check SCREENSAVER. But I do not do this. Only STANDBY HYBRID RUHE should be activated. I just want the PC to keep running for hours for downloads or radio recordings, but the monitor to darken to save electricity. This is no longer possible on three totally different PCs. It worked reliably under Win10. Each PC was freshly installed with Win 11 22000.194 from a MediaCreation stick. The installation went smoothly, although the processors were actually not reported as compatible by PcHealthTool. Win 11 runs very well. I use two interventions in the registry, which did not cause any problems under Win10 with regard to dontsleep. "Log in without a password" and "Elimination of the lock screen".
