Macbook Pro Mid-2015 randomly shut down, not light on charger, no signs of life
Hi
Last night my MacBook Pro 15" Mid- 2015 randomly shut down- according to the laptop it was 20% charged. I plugged my charger in and no light. I checked my charger and it works with other laptops so I'm guessing it's some type of computer problem.
Something interesting: When I plug the charger into my sister's laptop, it will charge normally and when I plug it into mine, the light shows, except after 5 minutes it will slowly fade to nothing.
I've tried SMC reset and I'm at a loss here. I got my Macbook's logic board replaced a couple weeks ago by a very respected business, so I'm super confused here.
