Hello,

I have no sound anymore. The "mute" key on the Lenovo ThinkPad keyboard remains lit. How can I unlock it?

Thank you in advance

Best regards

M

What you will do is uninstall the driver and reinstall it.

Hello,

You will just need to restart your ThinkPad.

During this restart, you need to quickly press the "mute" button once when the screen begins to turn back on. So don't wait until the end of the restart to press the button.

Hello,

excerpt from https://support.lenovo.com/au/fr/solutions/ht503647

Very difficult to catch a black cat in a dark room.
Especially when it isn't there...
