J'ai acheté un Macpro MD313 cet été. Mais après avoir branché mon ventilateur, le port ne fonctionne qu'avec le ventilateur. Quand je branche 1 USB, pas de signal de connexion. Pour 1 disque dur externe, il y a seulement que bruit du moteur dans le disque dur et la lumière qui clignote, par contre, sur le mac, rien n'est affiché, comme si j'ai rien branché.

 

J'ai essayé de faire Cmd alt P R mais rien n'a changé

 

Pourriez-vous me conseiller comment résoudre ce problème s'il vous plait?

 

Merci en avance de vos réponses.

    I bought a MD313 (2011 MacBook pro 13" i5) MacBook pro this summer. But after connecting my [USB] fan, the port only works with the fan. When I plug one USB, no signal connection. For 1 external hard drive, there is only noise in the motor drive and the light flashes, by contrast on the mac, nothing is displayed, as if I have nothing connected.

     

     

    I tried to alt Cmd PR but nothing has changed

     

     

    Could you advise me how to solve this problem please?

     

     

    Thank you in advance for your answers.
