A1278 Macbook 13.3" I purchased a liquid damaged A1278 13.3" Macbook on E-bay. When I recieved it itworked perfect except for the keyboard. I ordered a new keyboard and installed it but after reassemby no power. I have tried resitting the keyboard connection, power button, and DC board to no avail. I have been buying and repairing A1181 macbooks with success for a couple years but am stumped on my first A1278. Any Suggestions?
If it worked with the old top case and not the new, I’d question who your supplier is. Did you replace the top case or just the keyboard?
