Windows 10: Windows 11 - PC goes back to sleep even though all sleep/power settings are set to "never"

I currently have a wake timer set up on my Windows 11 pc that is set up to wake my computer using Task Scheduler, which allows some software to start running in the early morning, usually before I'm awake. This has been working fine for a while, but recently I discovered that my pc has been putting itself back to sleep after about 3 hours after each time the wake timer wakes it up. I ran a system power report using powercfg /sleep study, and it shows that for each time that the pc put itself back to sleep, an "offender" was encountered that lasted for the exact time that my computer was awak

Computer Sleep Option Missing in Settings

The Settings Power and Sleep menu in Settings should list Screen and Sleep, where Sleep is used to tell when the PC goes to sleep. Sleep is missing, so my computer never sleeps. Fast startup and Hibernate are not enabled. I used Tutorial Add or Remove Sleep in Power menu in Windows 10 to change the registry while in administrative mode, but sleep still is not seen. HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\FlyoutMenuSettings now lists :1: It was 0 before the change.

I cannot get a large image, so will type Default REG_SZ (value not set) ShowHibernate REG_DWORD 0X00000000 (0) ShowLockOption REG_DWORD 0X00000000 (1) ShowLockOption REG_DWORD 0X00000000 (1) I used Option 3 to add sleep using the Group Policy Editor. The steps seemed to work fine, but sleep is still missing. I’m using a “new” refurbished Dell T3500 workstation with mbr running the current version of win10. I have a number of these computers, and the other all have the normal sleep mode . Any suggestions? Jim
