Apple Macbook Pro 15" Mid 2015 Retina I7 2.5GHz 16GB 512GB SSD A1398.
Device functions as normal when on charger. When on battery power the device will shutoff while performing intensive tasks. More than likely needs a battery replacement. One was done previously with an “ifixit” battery, but I’ve read reviews of those possibly being faulty. I have since upgraded my device and have not had the time to reinvestigate the issue… will come with unit and charger.
