Réponse à : « Replace reed switch/hall effect on MacBook Pro »Same issue here (rMBP 13 Early 2013), even worst with the display, together with the keyboard light, blinking from on to black. As in your case, the keyboard and the trackpad do not work, and the clamshell status is often switching from ON to OFF. I would like to add a contribution: replacing the whole topcase (display, and so on) did not solve the issue. If one cannot replace such a part, does anybody know how to disable such a lid sensor via software? If not by disconnecting some cable inside? Thanks.
