Hello, Im new here but just wanted to register and chime in here. Im having some similar issues and recently have been going between visiting the apple store and also calling a support advisor.
Now firstly let me tell you my problem(s)... about 3 mos ago I bought a 17" MBP from a guy that was selling it because it was in disarray and he wanted premium dollar for it. So upon inspecting the unit which has noticeable damage and did not work properly and the batter was expanded I told this gentleman that I could not pay 1200 for his laptop and with the repairs needed would not pay more than 400. A few mins later he decided he wanted to sell anyways and gave it to me at that price.
So I started to review articles on how to fix HDD issues, it took forever to boot up, had been dropped several times has damage to the case etc, I ordered a replacement OS disk for 17 dollars from apple then I reinstalled and semi fixed the long boot time. Now my only issue is that it doesn't wake up the screen after I open the lid on the machine.
So with no DIY fixes in sight I decided to take it to apple for their advice, plus I read online that it might be a failing video card as it has the 8600gt card that has been recalled etc.
So I took the machine in and we sat there at the genius bar for 45 mins while she tried everything to get it to run the tests. She eventually gave up, she said its taking to long to boot, wouldn't boot off her diagnosis drives and so she said I can send it for flat rate repairs at a cost of $310 which I was in shock of and didn't follow completely to start. So I asked if she could explain.
The reason she said they do that is for customer loyalty. She proceeded to tell me that with the flat rate repair they would fix anything and everything that was wrong with my macbook pro for that $310 as long as there was no water damage inside the machine. She said it would cover the logic board, the hdd, the video card, the screen and the isight camera and the bottom case where it is dented.
Made me very happy because I only paid 400 and with this repair I can still sell the machine for around 900 and make roughly $150 on it or I can keep it if I want. I will probably sell it and get my money out of it since they are going to fix everything. But thats now and today, they do offer the service and it is a part of a tiered service plan they have.
But it does cover anything and everything that is wrong for the same price.
