I have a Core Duo MacBook, i got it the week they were originally introduced, I also have the AppleCare plan. Previously my MagSafe adapter has caught on fire. (they replaced the adapter) So you might say we have a love/hate relationship. So I'm just going to list the current problems. 1. Discolored palmrests. 2. Screen flickers, like the brightness goes up and down normally when i first start it up, also the display doesnt seem a bright as it used to be. 3. Almost constant freezing, it's pretty obvious it's a hardware problem since i've reinstalled OS X 3 times. (It passes the Apple hardware test) 4. MagSafe adapter light does not light up. 5. It gets hot for no reason, I'm sitting here just browsing and you would think that i am encoding video. 6. When the battery gets low it shuts down instead of sleeping. I really just want them to replace it instead of trying to repair ALL of that. So if I call do you think they will replace it?
