Our customer came all the way from Yokosuka to bring this MacBook Pro for repair. This MacBook Pro does not boot, after pressing the power button there is only a grey screen, not even the initial boot sound.
After diagnostic we found out a problem related to the hard drive and fixed it within two ours. After replacing the faulty parts with new parts, this MacBook is working again like new.
