G510 - 3.5 mm Head phone jack is not working


I am using windows 10 on Lenovo G510. A few days back my computer started to lose connection with headphone jack but after little bit juggling it got back. After doing this couple of days, it completely loses connection, it does not even detect the headphone when it's attached. I am using Conexant Smart Audion driver for audio, I tried to reinstall them but got no luck. I tried other audio drivers like Realtek audio driver but still nothing. In my Recording devices, I can see only speakers but no headphone even though it's attached to the computer. 

I think my sound card is not working but can be any other reason.

If anyone has any idea please let me know. 


Big thanks.

Hello Sheldoor

Thanks for using the Lenovo forums.

Sounds like your heaphone jack may have been disconnected from the MOBO potentially.


Try a static discharge for this, it may help to resolve the issue or at least get rid of any built up static on the motherboard.

(If the battery is internal, please just skip the remove/replace battery steps.)
1. Turn the unit off
2. Remove the battery and the Mains adapter
3. Press and hold the front power button for 30 seconds
4. Replace the battery and the Mains adapter
5. Turn the unit on as normal

Otherwise, try a factory reset, this would confirm if this is a hardware issue if the issue persists.

Note: Please back up all your data as running this reset will delete any data on your machine

1. Turn the machine off and press the recovery button which is located usually next to the power button. If you have a desktop machine you will need to power the machine back on and keep tapping the F2 key.
2. Use the arrow keys and press enter on system recovery. ( Desktop users can skip this)
3. Select “restore from the initial backup” and then “Next”.
4. Click “start” and accept the warning messages.
Length of time can vary depending on the speed of the machine.

Hope this helps, let us know how you get on.

In addition to Krakken,


There is usually a hardware switch in the socket, which is engaged when you put the plug in. Seems like it might be mechanically broken.


Update us how it goes.
