MacBook Pro 15 mid 2012 Pre Retina won't turn on or charge.
i have a MBP 9,1 (15”, mid2012, unibody A1286), 16GB, 1TB ssd, which suddenly wonʻt turn on. The magsafe charger LED does not light up, and no matter how long i leave it on the charger, it doesnʻt show any signs of working. Does anyone have an idea of what might be the issue. it was working perfectly fine before.
