Speaker Function and Safety Procedure

This repair may be required when the laptop produces no audio output through the built-in speakers. No advanced technical skills are required for this repair.

  1. Verify that the audio output is coming from the external speakers.
  2. If no sound is heard, check that the speaker is connected.
  3. If connections are secure and the issue persists, replace the speakers.
  4. Before performing any maintenance, ensure you are properly grounded.
    • To ground yourself, touch a metal object that is in direct contact with the floor for several seconds to discharge static electricity.
