Logic Board 820-3115-B 

Suitable for: mid 2012 13" Macbook Pro A1278 Intel i5 or i7.

This logic board has passed all of Apple's official Diagnostic tests and is ready to go for the laptops mentioned above. It was originally from a Mid 2012 13" Macbook Pro A1278 Intel i5 2.5 GHz that is no longer in use. I have a background in computer engineering so I was able to thoroughly test the logic board through all of the required diagnostic tests and can confidently say that it is in great working condition. I do accept returns within a 15 day period as long as my products are in their original condition. Please note that there is a 15% restocking fee. An extended warranty is available for purchase - simply message me prior to sending payment.

As a courtesy, I will include Apple approved heat sink grease for all of my logic board shipments. It is the exact same grease that Apple uses and it is necessary in order to prevent your laptop from overheating. If the listing includes the heat sink already attached, please note that I have already applied the heat sink grease on to the logic boards. 

The logic board requires professional installation. No returns for damage done during faulty installation. If you are not comfortable with installation ask about "install option".

Shipping: I ship within 1 business day of receiving payment. Your item will be sent through USPS so you should receive it within 2-6 business days.

Thank you so much for your time. Please don't hesitate to contact me.
