Hi, The other day I changed the thermal paste of my macbook, and accidentally I broke the flex of the battery indicator. After that, my macbook not sleeping when close the lid, I buy the part on this store: https://goo.gl/RNRLHo and I replace her, battery leds works well but not sleeping my macbook when close the lid. I tried with SMC reset and PVRAM and others software fixes…
You may have been supplied a faulty part. The battery indicator for this model is responsible for sleeping the Macbook when closing the lid. If the connector looks fine, and it has not suffered liquid damaged, it will just be the battery indicator causing the issue.
