Fully functional early 2013 MacBook Pro 13". Autostarts every time you plug it in.

Not sure what to do with this one. 820-3462 Replaced R6920, C6900-02 and C6994 to get power flowing back in from the MagSafe. The computer is fully assembled with battery attached but it still autostarts every time you plug it in, like there's no battery attached. Any ideas what might cause something like this? I attached some pre-ultrasonic pictures.

Probably corrosion around battery connector.
Did you tight the special screw, which enables the battery?

Yes, and it works fine on battery. Everything is truly fully functional, except that it restarts when plugged in.

Try turning off the machine from OSX (software way), at least one time.
Also do PRAM reset first.
