My Macbook is really slow without the charger.. In the Apple Hardware Test it shows the following error 4SNS/1/40000001:VPOR-1.057 I can not find anything on Google with the same error code.. Can someone explain this one to me?
That, unfortunately is a logic board failure error. Please give us a history of the machine. Is this the i7 model? Have you seen any anomalies with the screen like artifacts? Do not buy a logic board until you learn about Flat Rate Depot Repairs! Talk to us before making any decisions!
