Symptoms
- Screen flops or won't stay at an angle
- Cracking sound when opening or closing
- Visible gap or cracked plastic near the hinge
- Screen wobbles when typing
Likely causes
- CommonWorn hinge tension from years of opening/closingHinges loosen naturally with repeated use over time.
- PossibleImpact damage from a dropA drop or being carried in a tight bag can crack the hinge housing.
- PossibleLoose screws inside the hinge assemblyScrews can work loose over time, especially with frequent travel.
What to do
- Stop forcing the screen open past where it naturally wants to sit, since this stresses cables running through the hinge.
- Check whether tightening is possible from outside; most Chromebooks don't have accessible external hinge screws.
- Handle the laptop by the base rather than the screen when opening and closing to reduce strain.
- If the hinge is only slightly loose, using it more gently may be manageable short-term, but expect it to worsen.
- If plastic is visibly cracked or the screen wobbles significantly, stop use to avoid damaging the display cable, and get it assessed.
- A repair shop can replace the hinge assembly or the whole top case depending on the damage.

When to call a pro
A cracked hinge or one causing display cable strain should be repaired by a professional rather than continuing to use it.
Safety
Use caution
Avoid forcing a loose or cracked hinge, as this can snap internal display cables and cause a black screen or electrical short.
