Hello everyone,

I have this macbook pro :

Apple MacBook Pro A1502 Mid 2014
Main-Board : 820-3476-A
Serial n° : C02NF2AJG3QT
EMC2875

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 found that the macbook has entered hebernation mode which is popular on macbook 2010 to 2014.

I would be grateful if anyone could help me resolve this issue to exit this hibernation mode if it comes from bios which is attached at the bottom.
