Con un script AutoHotkey , puedes remapear el atajo de Win+L y crear otro para Dormir (elegí Win+S, normalmente no se usa a menos que uses OneNote):
#l:: ; Win+L
Shutdown, 0 ; this is the code for Log Off
return
#s:: ; Win+S
DllCall("PowrProf\SetSuspendState", "int", 0, "int", 0, "int", 0) ; DLL call to sleep
return
Hay más detalles sobre la llamada DLL en el archivo de ayuda de AutoHotkey:
; Call the Windows API function "SetSuspendState" to have the system suspend or hibernate.
; Windows 95/NT4: Since this function does not exist, the following call would have no effect.
; Parameter #1: Pass 1 instead of 0 to hibernate rather than suspend.
; Parameter #2: Pass 1 instead of 0 to suspend immediately rather than asking each application for permission.
; Parameter #3: Pass 1 instead of 0 to disable all wake events.
DllCall("PowrProf\SetSuspendState", "int", 0, "int", 0, "int", 0)
