So i don't know what i did. have a 820-3115 that had a bad hard drive. computer was booting up but stuck apple logo halfway on startup. checked the hard drive, diagnosied it bad so i upgrade to ssd and transfer the data with my data recovery equipment. i plug in the ssd today and now i only get fan spin for about 5 minutes until i finally get a chime and mbp will boot up either with old hard drive or new one.
only thing i noticed is that ppbus starts at 11.5v and slowly creeps up to 12 when it finally boots.
