My Macbook Pro is about 2.5 years old, in excellent shape, but it looks as if I'm going to have to take another trip to the Apple store tomorrow. It ran flawlessly for the first year and a half that I owned it, but then about a year ago, the graphics card died. I took it to the Apple store and they sent it in to have the Logic board replaced, and it was all goodnot a big deal. Then, about 6 months ago, my hard drive started to die. I would get frequent lockups, etc., until one month ago when it finally quit for good, and I couldn't even boot up. So I took it into the Apple store, they sent it out and replaced the hard drive and one internal cable that was damaged, and I got it back about three weeks ago, and it has been running great. Today, I was just sitting at my desk surfing the web, and all of a sudden my hard drive started making this loud scratching noise. I immediately powered off my MBP. I waited a bit to try to turn it on, but now it won't even boot upit chimes, then sits at the white screen indefinitely. So I have an appointment at the Apple store tomorrow. I'm still under Apple care. But my question is, at what point can I say "I am not going to be satisfied unless you replace my computer". For a hard drive to die within 3 weeks is absolutely ridiculous. I rarely move the computer from my desk, and when I do I am extremely careful with it. My Applecare is up in 4 months, and I don't want to be stuck with a machine that is going to be plagued with problem after problem. Should I bother asking them to replace the computer? What would be an effective way to ask? Thanks.
