BATTERY REPLACEMENT - MACBOOK 15" RETINA
Unless the Macbook was on the adapter, it went to sleep mode within 20 minutes. Battery needed to be replaced.
The repair time estimate of 2 hours was almost on the mark. However, it took almost another hour to remove the adhesive from the old battery.
Buy the magnetic pad. You can label the screws by step and pieces. Also, I said earlier that the repair took almost another hour to remove the adhesive from the old battery.
