Laptop Internal Microphone: failed microphone module. The microphone capsule or its electronics cannot convert speech reliably.

The distinguishing clue

The internal input remains silent while a selected external microphone records correctly.

Checks before an assessment

Record a short local voice sample with the intended microphone selected. Compare the input level and app permissions without uploading a private conversation.

Stop point: Microphone and camera wiring near the display bezel is easy to tear.

Workshop confirmation and repair

Device-level check: Check privacy permission, input selection and an external microphone before opening the display bezel.

Targeted check: Check microphone power and cabling and compare a compatible module. If confirmed: Replace the confirmed failed microphone module.

Repair boundary: Repair software settings or replace the confirmed microphone or cable.

Related cause to rule out

When the local recording cuts out with a previously observed lid position, also consider Laptop Internal Microphone: loose microphone cable before choosing a repair.

Checks after the work

After repair or replacement, check recording level, video calls, noise suppression and sleep recovery.
