Re: Audio combo jack vs headphone/earphone with mic and speaker connector

Welcome to the Lenovo Community !

 

On your computer the audio jacks along with the USB port are mounted on a card that is separate from the motherboard.  The two are then connected with a ribbon cable.  If your headphone jack is inoperable with more than one pair of headphones and the USB port does not work would be a good indication of a problem with the card.   

 

Just to rule out a possible hardware conflict try doing a BIOS reset.  Just do this.......


1. Unplug the charger / adapter.
2. Remove the battery.
3. Press and hold the Power Button for 15 seconds.
4. Re-install the battery, plug in the charger / adapter if needed and power up the system to see if the problem was resolved.

 

If the reset did not correct the problem then I would suspect either the audio card is faulty or the ribbon cable has become disconnected.  In that case I would suggest you contact Lenovo Support for additional service especially if your warranty is still active.  You can find the phone number for Lenovo Support in your country or area by using the link below....
