E7450 Light on F4 key will not turn off
On one of our E7450 laptops the light on the F4 key, mic, is continuously on. I have tried every suggestion I could get my hands on, minus banging it on the desk, to turn that little light off. I have searched this forum and the internet for the answer to this question but have come up empty handed.
Different remedies that we tried:
Of course we tried to turn it off the normal way with Fn + F4 - Nope
Hold down the Ctrl + Fn + Insert keys together for about 5 seconds. - Nope
Hold down the left Ctrl + Alt + Shift buttons and with your other hand hold down the same keys on the right. Release. - Still broky
Any ideas?
Thank you very much,
Lisa

Look at the Sound Settings, there needs to an active mic available. My light was stuck on until I enabled a microphone. FYI- My operating system is Windows 10

I have the same issue as Lisa (and an E7450). Alt+F4 does not work, as it is the Windows key combination to close the active window... (or shut down Windows in case the desktop is active).
This is annoying, as I need to use the built in microphone.

Remove the HD Audio driver and reboot the machine. Upon reboot windows will reinstall the driver for both the speaker and microphone. I did it just now.

I had the same issue of the light on an E5550 and some of the confusion over which keys work may be due to the setting of the function keys. By default in the bios - the F1-F12 keys work the blue icon mode by default. So F4 turned the light on and off, as did ALT F4 ( I don't think the ALT key was doing anything in this function mode ), FN+F4 will actually do F4 which will not change the light.
To check if your keyboard is in this mode try F1 to see if it mutes the sound.
To switch the mode so that ALT-F4 works like the close windows key, either change the bios, or press FN-ESC to change F1-F12 to normal mode.

On Win10:
Control Panel > Sound > select the Recording tab
select Microphone Array (this may or may not be something else)
Click Properties
On Microphone Array Properties:
Select the Levels tab
Deselect Speaker icon (aka un-mute microphone)

Its working for me enabling 'Microphone array as default device'.
Though when light is ON Microphone is Off, When Microphone is ON Light is Off
