- Check for Dirt or Debris
Look closely at the headphone jack with a gentle light. If you can see visible dirt or debris, be sure to clean it out thoroughly using a cotton swab. Be gentle, as you don’t want to break the headphone jack. - Connect to an External Speaker
If you can hear sound from the external speaker, the issue may be with the headphones or headphone jack. Make sure to switch to different headset or pair of headphones for testing. - Replace the Headphone Jack
If none of the initial troubleshoot steps worked, you may need to replace the headphone jack completely. If you have experience soldering and feel comfortable going this route, you can replace the headphone jack yourself. Otherwise, you can take the laptop to a professional to complete the replacement.
