Laptop Display Connection Path: wrong cable or connector revision. A replacement fits physically but uses different pin mapping or supported features.

The distinguishing clue

Basic power may work while data, video or sensing does not.

Checks before an assessment

Record any lid position that already caused the problem. Do not repeatedly flex the hinge or squeeze the bezel to reproduce it.

Stop point: Continued lid movement can turn an intermittent conductor into a short circuit.

Workshop confirmation and repair

Device-level check: Observe gentle lid movement, compare an external display and inspect cable routing with all power removed.

Targeted check: Compare part numbers, pin count and supported protocol with the original. If confirmed: Install the correct revision and inspect for mismatch damage.

Repair boundary: Repair the confirmed cable, connector or interface stage and correct hinge pressure that caused the damage.

Related cause to rule out

When power may be present while data, video or negotiation is absent, also consider Laptop Display Connection Path: interface controller fault before choosing a repair.

Checks after the work

After repair or replacement, check full hinge travel, camera, brightness, sleep and a sustained video test.
