Ayer noté que cuando fui a reiniciar mi computadora portátil, no funcionaba. La computadora es una Dell XPS 13 9350 nueva. Después de investigar algunas cosas, noté que solo sucedería (no se apagaría) después de que pusiera mi computadora en modo de suspensión, ya sea cerrando la tapa o suspendiendola manualmente. Hice un análisis dmesgy descubrí que había algunos errores de ACPI al inicio y después de que se activó la suspensión o activación.
Aquí hay un mensaje al inicio, que parece repetirse varias veces.

Algunas de las cosas que encontré me indicaron que debía actualizar mi BIOS, pero mi BIOS ya está actualizado a la última versión, que actualicé la semana pasada. Cualquier ayuda sería muy apreciada. Puedo proporcionar más información si es necesario.
