I must have had a power surge because my laptop’s MagSafe adapter is burnt out, as well as the I/O Board. I ordered a new I/O Board from ifixit, and replaced it, but it still doesn’t start. I noticed another burned place on the logic board and have attached a picture. Does this mean the entire logic board is bad and needs to be replaced? If so, is it worth it?
