So, how loose should the hinges be?

    I ask because I remembered a thread about loose hinges here a while back. So I decided to test the hinges on my new 17'' MBP. Anyways, it can't even reach 90 degrees (It ALMOST gets there though... I'd sa it reaches about 75-80...) before it starts to close. If I hadn't heard about it here I would have never have thought of it as unusual (as the screen on this thing IS freaking huge), but yeah... Just wondering if this is normal. =S

    Yes, the 17" MBP has a particularly loose hinge in it. I can't use the thing sitting in bed at all. You'll notice it barely holds it's own as soon as you tilt it beyond about 10 degrees from vertical (towards the keyboard).

    Ah, well I guess it's good to know that this wasn't just mine. =/

    The 17" uses what's called a counterbalance hinge which basically does just that; when on a flat surface, the springs will counter the weight of the display and keep it up; when you go off axis, the springs can't counter the weight anymore, so the display falls.

    The 15" and many other computers use what is called the friction hinge.
