Macbook A1181 2.16 GHz Rebuilt a Macbook as the bottom case was badly damaged. Everything is connected OK, fan magsafe etc. The issue is when I plug the magsafe in from the macbook being off it boots automatically without touching the power button. tried resetting PRAM etc but still have the issue.
When a topcase is not present, a lot of these A1181 boards will power on automatically once connected to power. Is your topcase connected and working? I’d re-seat the connection. If that doesn’t do it I’d try a different topcase in order to rule out the original.
