Hi Troy,
I'm the one about 2 or 3 posts back. Same 2009 model A1811 as yours. (It's my daughter's) Asked lots of questions everywhere on line, got lots of different answers. Seems to me like it depends on the Apple service place itself and maybe also their own relationship with Apple. I get the impression nothing is written in stone. Essentially, 1 year warranty on that top plate and everything else (exlcusing clear abuse), somewhat more (maybe 3yrs more??) if you bought Applecare(R), which we did not. My daughter's whole top plate was replaced free within its first year. This past year -- before the 4 year mark -- the plastic around the screen -- both front and back -- were covered for some reason they had a hard time explaining to me. They had to look into it, ask Apple and get an answer. Maybe the person at Apple was in a good mood. I think they, themselves, have to feel out Apple to see what Apple will cover. 4 years seems to be the cutoff for everything -- except when it's 5 years. For reasons unknown. We really didn't need the top plate replaced this year (before the 4 year mark), but it was developing a few little chips. It's about $170 because it has the whole keyboard and touchpad built into it. I had to have them replace the hinges (the metal ones inside, which were really going), and the hard drive, which was developing a lot of bad blocks (imminent death if you're going to go from Leopard to Snow Leopard, as I was planning to do. Total diagnostics -- I mean like EVERYTHING -- for $49. Had to pay for all the dissassembly (it's a lot!) and the hinges. The people I know did a wonderful job with that: $85 to replace the old, battered 160GB HD with a brand new 500GB drive (smallest they even have anymore), load it with Snow Leopard (as far as that model can go), transfer ALL the stuff and update ALL the programs. ALL for $85, and that followed extra, extra dianostics that were gratis. But they are an unusual place. Don't know where you are, but as I say a page back, I highly recommend Digital Society in NYC. Stay away from Tekserv!!!!!!!! $250 just to walk in the door and get your hand stamped. More if you actually order a cup of coffee. HOW ON EARTH my guys managed to call Apple and get Apple to pay for a whole new top plate (plastic plate, keyboard and all) --$170 -- I do not know.
But from what I've seen, the 4 year, 5 year, 1 year thing seems to be an irrational variable. Based on calculus, or irrational math of some sort, or prime numbers, or sun spots....maybe just ask 10 places. Luck be a lady tonight, as Brando said in Guys and Dolls. Sorry. I wish I had an answer. I've looked and looked and can't find a real, hard and fast answer anywhere -- just individual experiences. Maybe ask a dozen places, find the nicest one, ask for a new HD and hinges (you might need them anyway at this point -- who knows?) and maybe they'll get you the top plate courtesy of Apple. Maybe if you flirt with the tech person. Who the **** knows???????????
