Hi, I'm kind of in a ****** situation as I have a deadline for my thesis, but my Macbook Pro is not cooperating. I'm also in Mumbai, India which doesn't help, as there are no, or far away, official Apple stores. Situation: Macbook Pro (late-2013) randomly shuts down, can sometimes be after 1 hour and sometimes be after 5 seconds. If the computer stays on, it works absolutely fine. SMC and PRAM-resets didn't work. Diagnostic test show no issues. Macbook charger light always comes on when plugged in. Went to a local sketchy Indian repair shop, he said immediately it's a logic board problem. After one day he said he replaced a part in logic board and Macbook seemed fine for the day (paid around 125 euro). Morning after (today) experienced the same problems; random shutdowns. Guy doesn't want to refund me, as agreed before, but wants to investigate further. Does this seem like a ordinary logic board issue? Should I let the guy "repair" further, I'm afraid he will only make matters worse, or should I try another laptop repair shop? Thanks!
