bonjour à tous,
je suis un technicien à la retraite, et j'adore bidouiller les PC et toute autre chose qui s'en rapproche, et la je suis sur un HP Probook 440 G9 qui est bloqué par un MP sur le Bios, et en faisant des recherches, je suis tombé sur votre forum, et celui ci a l'aire d'avoir une bonne étique en ce qui concerne l'aide pour pouvoir avancer et toute cordialité et c'est cela qui m'a plus.
