Symptoms
- Screen visibly wobbles when typing or moving the laptop
- Screen doesn't feel solidly connected to the base
- Wobble is worse at certain angles
- Hinge may also feel loose or make noise
Likely causes
- CommonHinge tension mechanism has worn down significantlyOnce tension wears past a certain point, the screen loses the rigidity it once had.
- CommonHinge mounting screws have loosenedVibration over time can loosen the screws that anchor the hinge to the case.
- PossibleHinge assembly has partially cracked or separated internallyMore likely after a drop or being opened too far.
- PossibleCase plastic around the hinge has weakened or crackedThe housing, not just the metal hinge, can be the source of the wobble.
What to do
- Check the bottom panel for any accessible hinge screws and see if gently tightening them reduces the wobble.
- Avoid typing forcefully or bumping the laptop while the screen is open, since this can worsen the wobble.
- Support the screen with a free hand when adjusting its angle until it's repaired.
- Note whether the wobble is worse at specific angles, which can help pinpoint where the hinge mechanism is failing.
- Avoid carrying the laptop open, since movement puts extra strain on a weakened hinge.
- Get a repair estimate rather than continuing to use a wobbling screen, since it risks damaging the internal display cable.
Tools and parts
- Small screwdriver (for accessible screws only)

When to call a pro
Hinge replacement typically requires professional disassembly to avoid damaging the display cable that runs through the hinge area.
Safety
Use caution
A wobbling screen risks stressing and eventually breaking the display cable that runs through the hinge; avoid forcing it or using it roughly until repaired.
