My mid 2013 macbook Air model stays stable in 90 degs, 120 degs all angles when it is grounded , but on extending the computer from the base, the screen falls back. IS it normal???

    That's not normal. Take the MacBook to an Apple Retail Store or reseller and it will be repaired or replaced for free. Make a backup of your files with Time Machine

    I haven't got a MacBook Air, but I used some of them at an Apple Retail Store. They didn't do what your MacBook is doing

    macbook Air model stays stable in 90 degs, 120 degs all angles when it is grounded (laying FLAT on a table) ,

     

     

    It is normal.....your Air is fine

     

    Youre lifing your Air up and claiming that the monitor will flop open at or past 90 degrees.   Normal.

     

     

    Learn what you can do if you experience one or more of these issues with the hinges on your MacBook Air.

    • Unable to close lid completely.
    • Broken or cracked plastic near one or both of the hinges.
    • More than one inch (2.54cm) of free play while opening or closing the lid.
    • Lid falls freely into closed position from a 30-degree open position. (From a closed position, open the lid approximately 30 degrees and let go.)

    END from Apple.com

     

     

    Due to the thin nature of the LCD backlit LED monitor on the Air, you would NOT WANT a very tight hinge.

     

    Why? Excessive hinge resistance would cause the screen to BOW (and possibly crack), especially on a longer fulcrum from the hinge in the case of the 13" screen...... Ergo it is designed logically to be “looser than” a traditional macbook Pro's hinges for a very good reason.

     

    Friction Hinge:

    A device with torque between two parts on a common axis.

     


       A friction hinge is also commonly known as a:

    Constant Torque Hinge, Position Hinge, Clutch, Torque Hinge, or Detent Hinge.

    Ive owned 3 Airs, some of the friction hinges are a hair tighter than others, but nearly all (never seen one that wouldnt) WILL IF you lift them up when at a 90 degree angle, ....if you lift up quickly, or tilt it back a bit,...the screen will flop open.

     

    Friction hinge in the AIR see pic below  (there are NO SPRINGS in these kind of hinges)

    My MBAir's lid hinges are "loose" when compared to my MBP, but it does not fall open (or closed) on its own when the lid is opened past 90 degrees; it is only one month old though.

    PlotinusVeretas the post looks like the middle part 'Learn what you can do...........' up until "End from Apple" is from an Apple support article (white paper). Is this the case, and if so; what is the link to the support article?

    Yes, Ive got 2 macbook Pro and my current 2013 Air.  It is invariable and designed to be "looser than" hinge for the macbook Pro.

     

     

    Yes, "on its own", as per Apples specifications.  

     

    My older Air I sold off, after using it like mad around the globe, the hinge never loosened up any nor my Air before that, unless it was so minor as not to notice.

     

    The ONLY TIME Ive seen a macbook Air hinge NEEDED to be replaced was due to a drop, accident, or someone slamming it open like when you slam a door open very hard.

     

    The nature of that friction hinge is such that your change in its momentum upon LIFTING IT or in TILTING IT backwards under its own weight is = normal finger open / closing pressure.

     

    then obviously it WILL move when lifting it or tilting it back when raising it.
