Le voyant de charge s'allume en orange et Windows 10 indique "Branché, en charge", mais le pourcentage reste strictement bloqué à 48%.

J'ai déjà tenté :

- Une réinitialisation matérielle (drainage des charges de la carte mère sans batterie)

- Une vérification dans le BIOS (informations visibles mais pas d'option de calibration)

- La désinstallation et réinstallation des pilotes de batterie dans le Gestionnaire de périphériques.

Le problème persiste malgré tout. Avez-vous une idée de ce qui pourrait bloquer la charge ou empêcher l'évolution du pourcentage ? Merci d'avance pour votre aide !
