My son spilled soda into 13"MB early 2011, I did not get to repair for 6 weeks. Machine took over twice typical time to start-up and once running, cursor showed stuttered movement and launching applications was very slow.
I used guide (only steps 1-19) to remove logic board and delicately cleaned with very slightly damp Q-Tip (using Windex electronics cleaner) & dried, every place I cleaned, using compressed air. I did not remove the heatsink, as I assumed the paste protected the processor underneath.
Once cleaned, I reversed all steps and it booted quickly and all other issues disappeared. THANK YOU!!!

Do you send to Brazil the same Logic board above Its the Early 2011 MBP A1278 with the Core i5 2.3 GHz processo. It had many issues with it’s Logic boar and I think it’s a manufacture defect. I’m so desaposentes with apple planned Obsolescence, ando no repair. It’s not the same apple. My computer was boutique inAustralia , so I’m protected by their consumer act(2010) I just have to prove it was a hidden problem.
My track pad was difficult to "click". I've replaced batteries before, so I knew that it was definitely a swollen battery. However, when removing the damaged, swollen battery, I used the end of a flat head screw driver to pry up the battery connection... DON'T DO THAT! I saw the tiniest of sparks around pins 4-5-6 on the 9 pin battery connector. New battery installed, but the OS didn't recognize the new battery -- black "X" over the battery indicator. Further, the wall charger would not recharge the new battery. Instead, the computer ran off the 30% charge that new batteries are shipped with. I ordered another new battery, and after draining a second battery without being able to charge, I figured that spark was the sign that I fried something in the logic board. Indeed that was exactly the case, and logic board replacement did fix the issue. I found these instructions INVALUABLE in replacing my old logic board.

Thanks!
