Customer: Julie, WA 6156

Machine Model: 15” MacBook Pro A1286 Year 2011

Fault Descriptions: Grey screen with wavy lines, cannot log in most of time.

Investigation: AMD GPU failing, but not completely dead yet

Solution: Remove all AMD GPU functions and connect the screen direct to internal Intel graphics chip.


  1. No software including Photoshop are affected by the removal of AMD GPU.
  2. MacBook is running 15 °C cooler than before. GPU overheating problem fixed forever.
  3. Battery lasts about 10% longer than before.
