Lately I have notice what seem like bruises on my Blackbook screen. I take good care of it, using an Incase hardshell case and a Radtech screensaverz, but it was in for repair recently at an Apple store. I have aso identified 2 stuck pixels. Do you think Apple would replace my LCD? I'm still under Applecare. I've had several other issues with this machine, including a DOA battery, dead charger, and palmrest crack.
