También encontré este comportamiento:
En modo AC, si desactivo Bluetooth, el sistema se suspende correctamente (lo intenté varias veces). En modo Batería, siempre funciona bien.
Realmente no entiendo lo que está pasando.
PD: Perdón por mi inglés.
Gracias
¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡actualizar!!!!!!!!!!!!!!!!!!!!!!! Bueno, parece que todo es aleatorio. Luego otra cosa que hice fue:
Me di cuenta de que acpitool puede cambiar de dispositivo para no despertar de la suspensión (según lo que leí)

No me gusta esta solución pero es lo que tengo por ahora. No sé cómo hacer que esta configuración sea permanente porque perdí los cambios después de reiniciar. ¿¿¿Alguna idea??? Tengo miedo de tener algún efecto secundario.
gracias de nuevo
