lately my notebook has been getting really hot and just shutting down or sometimes when im dj'n with traktor, it'll just shut off. i've been reading up on similar issues and noticed that all the models that were produced the year i bought mine, have a defective logic board that was recalled but i'm just finding out about it now and no longer have any type of apple care coverage. would i be able to just buy a new logic board on the internet and fix my problem?
