My laptop is macbook pro C2D M609 . Recently LCD have one big dot. (0.5mm*0.5mm<bot<1mm*1mm) It is gray.
I call support.He say it is normal.
normal ???
I think you have a "stuck" pixel, which means it is partially dead. You may be able to do the cloth trick as DigitalN. recommended, otherwise there are many programs outthere to fix stuff like this.
Though it is not normal, the Apple guy on the phone was kinda right, they will not repair your screen for 1 stuck pixel.
