This is what the "new", 3 or 4 year old, Dell 5010?? laptop runing win
11 shows for possible sleep states: 

PS C:\Users\mmm> powercfg /a
The following sleep states are available on this system:
    Standby (S0 Low Power Idle) Network Connected
    Hibernate
    Fast Startup

---So it doesn't list S3, or Hybrid Sleep, only S0.  So I won't have
Hybrid Sleep anymore?? ---

The following sleep states are not available on this system:
   Standby (S1)
     The system firmware does not support this standby state.
     This standby state is disabled when S0 low power idle is supported.
   Standby (S2)
     The system firmware does not support this standby state.
     This standby state is disabled when S0 low power idle is supported.
   Standby (S3)
     This standby state is disabled when S0 low power idle is supported.
   Hybrid Sleep
         ----- So S1, S2 and S3 are all disabled when S0 is supported. 
               So S0 must be awfully important.  How come you don't  
               want it, Stan?  Or is this a different S0? 
     Standby (S3) is not available. ----- But I want it!!!!!
