Hello everyone,
I have a macbook pro A1502 820-3476 which had a Sierra High OS, after formatting it under Windows 10 it became very slow, I decided to return it as before, the formatting went well but the charging of my macbook was interrupted then I turned it on to continue the installation of mac Sierra high OS and it finished well; but after turning it off and on again, it doesn't turn on .
after a search on the net I think it entered a hebernation mode which is popular on macbook 2010 to 2014.
