Solved Macbook Pro Won T Turn On After Battery Replacement Macbook Pro 15 Retina Display Mid 2012
Chosen Solution I replaced the battery in a mid 2012 macbook pro. When I plug the magsafe in there is no color on it, but the two fans start to run. The speed on the fan go up and down. Can anyone help me with this? If you haven’t replaced the battery yet lets NOT DO THAT!! Instead lets walk through a basic diagnostic process to find out whats wrong: You need to ask the customer for some level of background info like what happened when it stopped working, Did the system get banged or dropped?...
