P51 Mute Button issue

I searched and did not find this problem previously. My mute button above my keypad is malfunctioning. Upon boot, it is active with the orange light.  When pressed the on screen display comes up to shot the laptop being unmuted.  Unfortunately, everything is still muted despite it appearing not to be. 

 

Any ideas on how to turn that button off or fix the issue?

Yes, it was being caused problems by the FN mute button.

Re: P51 Mute Button issue

Thank you so much!

For future me when this happens again (and anyone else wondering what to do to fix it):

There are *two* mute buttons on the Lenovo P51. Pressing F1 will mute the computer much like pressing the mute button above NumLock. If pressing one doesn't work, try pressing the other.

Re: P51 Mute Button issue

Oh man, I had high hopes for this fix! My P71 is stuck in the same state, and it's been stuck there before. 

 

I've tried both mute buttons and volume up/down buttons to no avail.  The OS is certainly seeing the change, as the software volume mixer mutes and unmutes just fine, but the light never goes out and the sound never plays Smiley Sad

 

I'm guessing this is a BIOS thing, last time only a reboot fixed it.

 

Hah, and as I'm writing this, I tried out a set of bluetooth headphones, the sound worked fine and the mute button light went off.  When I turned off the headphones music started playing through the speakers again!!

 

Might want to add this to the list of "fixes" for this issue.
