My daughter's MacBook Pro "Core i7" 2.4GHz 15" (Late 2011) had its logic board replaced 2 years ago due to the soldering issues on the video card. At the time, it was fully paid by Apple under the extended warranty. Two days ago, the laptop started exhibiting the same type of display artifacts. Several reboots did not fix it. The battery was close to 0%. After the battery was exhausted and fully recharged, it rebooted fine and has not shown any artifacts since. This bring a few questions: Can the battery charge level cause any display issue? Was the replacement logic board installed in 2015 supposed to be free of the defect that affected the original? Of course, this happens exactly 1 month after Apple made this model "vintage".
