battery charging, DC-in board(or Magsafe board?)
My 15 inch Pro is
not charging batteries and shows bad connection status when diagnosed at the Mac store.
Other known good charger gives the same status. Is this an
indication of bad Magsafe board, or left I/O board? Are they one and the same part?
(they referred to it as a DC-in board)
They also noted to me that there was some heat on the underside in the
back center under the logic board area
that didn't seem normal after a short time active.
Is this a good question?
