Laptop Internal Speakers: speaker amplifier power fault. The speaker amplifier lacks a required supply or enable signal.

The distinguishing clue

Both speakers remain silent across applications despite correct routing and intact leads.

Checks before an assessment

Play the same familiar recording at a moderate level, checking left and right balance. Note whether headphones work and whether the speakers are selected as the output.

Stop point: Loose metallic debris near speakers can contact the motherboard.

Workshop confirmation and repair

Device-level check: Compare headphones, balance settings and firmware sounds before inspecting speaker wiring.

Targeted check: Check the amplifier supply and enable path against the laptop's circuit design. If confirmed: Repair the confirmed amplifier power path before fitting speakers.

Repair boundary: Replace the damaged speaker or repair its amplifier or cable path.
