I called Dell and a technician named Aayush logged in remotely and after a couple reboots he figured it out. * Checked USB Wake options in BIOS* Disabled Fast Startup* Refresh the hiberfil.sys file I have to give dell props for their overall support system. They even sent a guy out to replace a fan because it was too noisy, and I live out the boonies. 
Just got this Inspiron 3910. Windows 11 has it set for 15 minutes to go to sleep but it never does, I just turn it off thing off. I can manually set it to sleep but it comes back on at some point so I just turn it off to make sure.  I've never had this problem with any computer. Still under warranty so I'll give them a call. Just thought I'd familiarize myself with the message board and add my 2 cents. Seems others have this issue too. I'll update after I speak with service.
Inspiron 3910, works so hard it never sleeps
