hello to all. I just bought a 2010 MacBook Pro 15' at a pawnshop and said no password. I was able to get APPLE customer care to unlock and download Sierra. Just a couple of days ago it has been shutting of then starting up with no warning. did your work on your own MACs work??? Update (06/14/2017): please send me a picture of the C9560 and one of the 330uF to identify what needs to be removed and what needs to be installed. What I looked up doesn't look like anything on the laptop circuit board/s. thanks!
