Symptoms
- Visible crack in the plastic near where the screen meets the base
- Crack seems to widen slightly each time the laptop is opened
- Screen or hinge area feels less rigid than before
- Crack appeared after a drop or being opened at an odd angle
Likely causes
- CommonRepeated stress at a weak point in the plastic housingThe plastic around hinges takes the most mechanical stress of almost any part of the case.
- CommonImpact damage from a drop or being closed on an objectA single impact can crack plastic that then continues to spread with normal use.
- PossibleOpening the laptop from one corner rather than the centerUneven opening puts more torque on one side of the hinge, encouraging cracks.
- PossibleAge-related plastic brittlenessPlastic can become more brittle over years, especially with heat exposure.
What to do
- Open and close the laptop gently from the center of the lid rather than from one corner.
- Avoid putting any additional pressure or twisting force on the cracked area.
- Consider a temporary plastic-safe adhesive or brace only if you understand it's a stopgap, not a permanent fix.
- Watch for the crack lengthening or the hinge becoming loose as a sign it needs prompt repair.
- Avoid carrying the laptop by the screen or lid, which stresses the cracked area further.
- Get a repair quote for a case/hinge cover replacement rather than letting the crack worsen.
