After Silo's death, Adosinda engineered the election of her nephew Alfonso, son of Fruela I, as successor. The adolescent was named governor of the Palatium Regis, roughly chancellor. The throne was then seized by Mauregato, son of Alfonso I and of a slave woman of Muslim origin.
Due to the support she gave her nephew, her position in court became insecure and she was forced to enter the Monastery de San Juan de Santianes de Pravia on either 26 November 783 or 785, according to the chronicle of Ambrosio de Morales. She became a nun in the presence of the Abbot Fidel, De Beato and Eterio. The latter are known for the controversy with Elipando de Toledo, Archbishop of Toledo.
It is unknown how long Adosinda spent in the convent. Some authors say she was there until her death.
