Pattern to record: The lid is square when open but shifted or rubbing when closed.

Locate the moving or damaged part

A convertible hinge has a specified rotation range and cable route for laptop, tent and tablet positions. Stop at the first abnormal resistance rather than forcing a full rotation to demonstrate the fault. One possible explanation is that the left and right sides were tightened in conflicting positions.

Support the assembly

Do not force a convertible hinge past a tight point because bonded display damage is costly. Forcing the lid shut can crack the panel edge.

Mechanical inspection

1. Test movement only within the safe range, inspect rotation stops and compare sensor behaviour with mechanical alignment.
2. Loosen only with full support, establish neutral alignment and inspect for pre-existing deformation.

Fit and movement after repair

If the checks support this cause, realign the assembly in the correct sequence and replace distorted parts. Verification should cover all supported positions, mode sensing, touch, display, cable clearance and sleep.

For an assessment of your convertible laptop, contact AEPC in Burswood or call 027 908 8880. Provide the model and the conditions that reproduce this problem. Workshop visits are by appointment.
