Chosen Solution
Hi, This is my first question here! I have a 13” MacBook Pro retina (A1502) for few years. Everything was fine until the past 2 weeks. About 2 weeks ago, I got a strange situation where I couldn’t turn it on my systems for a while after it discharged completely. I plugged it into a MagSafe power adapter for a night and it normally started next day. Today I got same issue but even fully charged it couldn’t start. I’ve tried some keyboard magic but reseting SMC (in every single way I found possible) nothing worked. I bought P1 & 2 screwdriver and decided to open it up. The first wierd thing was the fan which was keeping turning at lowest speed. I disconnected the battery, fan stopped. I cleaned the Mac, and disconnected SSD. I tried to power it on only on The MagSafe adapter, the fan started but nothing more happened. I put the system back together, tried some more combinations this time with PRAM. Nothing! Any ideas where to find a solution? I must admit local service is the last on the list. I hope I can do it by my own. Thanks for any answers
Try connecting the magsafe without battery and ssd, to rule out a possible ssd and logic board failure..the screen should light up with a question mark folder. If that doesn’t give the expected result it might be a screen or logic board failure. Reinstall the ssd and plug your thunderbolt to an external screen/tv..if that doesn’t work it’s a logic board issue for sure and you’ll need service or replacement. If it works it’s probably “just” a screen issue.
