El MBP se apaga durante el sueño

Suelo poner mi MBP 2018 en reposo cerrando la tapa (sin ningún programa abierto) y la próxima vez solo tengo que abrir la tapa y desbloquear con la huella dactilar. Sin embargo, recientemente ha adquirido un comportamiento molesto al apagarse ocasionalmente durante el reposo, obligándome a iniciar sesión con contraseña más tarde.

Este es un extracto de pmset -g log comando:

Así que, a las 3:19 de la madrugada, el portátil se puso a dormir: Entering Sleep state due to 'Clamshell Sleep':TCPKeepAlive=inactive Using Batt

Sin embargo, 3 segundos más tarde hubo una solicitud de despertar de [*proc=powerd request=TCPKATurnOff inDelta=43257] . También HibernateStats hibmode=0 standbydelay=0 .

Realmente no sé lo que significa. La próxima vez que abra la tapa a las 15:27, esto se puso en el registro:

Ya he desactivado Siesta energética y Despertar para el Wifi , intentó reiniciar la NVRAM y el SMC. El problema sigue ocurriendo ocasionalmente.
