Error extraño de entrada del teclado y tactil [selección]

Hola éste es mi segundo post por aquí

El día de ayer mi laptop Acer (A515-43-R19L) empezó a presentar problemas, comportamientos inusuales.

Las luces de la batería y el cable alimentación. La luz de la batería cuando está suspendida parpadea muy rápido, y antes lo hacía intermitente lento.

Noto se baja la página completa donde estoy en el navegador, explorador de archivo y en la terminal se escriben un poco de caracteres.

El teclado con retroiluminación, que cuando no hay actividad se apaga, nunca lo hace.

Corro Manjaro como sistema operativo desde hace más de un año en esta máquina. No sé que sucede.

Intenté formatear el disco, con Manjaro KDE (el mismo que tengo ahora mismo), porque pensaba que era un error de actualización ( la última actualización fue el 30-07-2022 y no presenté problemas), noté que en las opciones tras iniciar el live de manjaro, pasa lo mismo baja la selección hasta la última y corriendo el live pasa también lo mismo.

Para un video del comportamiento aquí dejaré el link a GD para que lo miren:
video de comportamiento extraño

El video no me carga, pero por lo que comentas diría que tienes un fallo físico en el equipo que afecta como mínimo al teclado y se generan pulsaciones “fantasma” (supongo que de la tecla cursor abajo) que provocan ese comportamiento.

gracias por su respuesta, estoy llegando a la misma conclusión :frowning:
