2010 MacBook Pro 2.53 Repair #1- SD card slot never worked, Apple store replaced logic board. Repair #2- Displays go dark after 1/2 hr to 3 hours. Apple store suspects discrete/integrated chip handoff causing issue. Replaced logic board. Repair #3-Brought home after repair #2 and noticed "spotlights" along bottom of display (missed it in store due to dock hiding the issue). Apple store suspects bad display (obviously the bottom LED bar is dead) Repair #4- Went to apple store to pick it up after repair #3, genius and I immediately saw "wavy" display defect in middle of screen! Solution yet another display replacement.* I strongly suggested a store credit or new machine to stop this endless cycle of pain. Apple store guy suggests 5 is the magic number....what else could possibli go wrong??? Luckily still 6 more months of warranty left...what can I do????
