hello i just opened up my 17" macbook pro, and everything seems fine except for one thing. the screen seems very eager to close. it seems almost like the hinge of the screen is loose, and when the laptop gets angeled at all, the screen falls forward and shut. usually its ok, but when moving hte computer, even gently, often the display falls shut. im guesing this isnt normal? just i call apple about this, or am i being ridiculous. i do feel lucky i dont have any other issues. is the hinge on the 17" an issue/bug i should get checked out? on a side note, how can i tell if apple underclocked my video card, and is it easy to clock it back up to the norm?
