Hi guys , recently I had the same issue. I waked up and unplugged the mac (knowing that it has battery issues it was kinda dumb tho) so I took it to the living room and bam it shutted off (at97%) first time I thought it was normal (cuz it always does this) then 10hours later it won't just power on. Its been 4days now. I did all the combinaison s buttons but nothing. Only things that turn on are the magsafe and the battery status on the side left. Can someone help me ? Also I can't unscrew the back of my mac cuz my dad won't let me do it. Any help is appreciated.
