Laptop Headphone Jack: failed headphone jack module. Worn internal contacts cannot reliably connect a compatible plug.

The distinguishing clue

One channel remains absent with several verified compatible headsets.

Checks before an assessment

Compare a known compatible wired headset at a moderate volume. Note whether the plug is detected and whether one channel, both channels or the microphone fails.

Stop point: Broken plug fragments should not be dug out with the battery connected.

Workshop confirmation and repair

Device-level check: Test a known headset, inspect the socket and compare detection across restart.

Targeted check: Compare the jack contacts and a compatible replacement assembly. If confirmed: Replace the confirmed failed jack or daughterboard.

Repair boundary: Clean or replace the jack, or repair its sensing circuit after software routing is excluded.

Related cause to rule out

When wired audio drops out while internal speakers continue playing normally, also consider Laptop Headphone Jack: loose jack-board connection before choosing a repair.

Checks after the work

After repair or replacement, check both channels, microphone where supported, plug detection and movement.
