Hi, I faced this issue last year for quite a few times!! My MacBook battery was drained by an external usb device (sound card) so my computer died and it dint charge with the regular charger and I was worried and took it to service center and they told I had to change my logic board! But I asked them to disconnect the battery and connect it again and after that I charged and laptop revived. After few weeks again battery drained by the same usb device and this time the same solution dint work. I kept the computer aside for few days and then charged it again and it worked. My laptop is still up and running
