Mac apaga la fuente de alimentación cuando está en reposo

Estoy enviando mi computadora portátil a dormir ( - > Dormir) y cuando la abro más tarde, comienza a cargar el sistema desde el principio como si lo hubiera apagado. Pierdo progreso en mi trabajo debido a esto.
No encontré dónde puedo deshabilitar este comportamiento en la configuración. Esto comenzó hace unas semanas (después de la actualización del sistema, supongo).

¿Es una manera de arreglarlo?

macOS 10.13.4 (17E202)
MacBook Pro (15 pulgadas, 2016)

EDIT 2

Mis acciones después del día de trabajo:
- desconectar el cable de alimentación del portátil
- Haciendo clic para dormir ( - > Dormir)
- Cerrar la tapa del portátil.

La computadora portátil se apaga, no porque haya poca batería en el modo de suspensión, lo he comprobado (después de dormir la batería, no menos del 80%).
