Toughbook CF 53 I used the Fn & F4 key to mute my speakers, but when I went to turn the volume back up it now will not play anything through the speakers. I can plug in headphones and the volume works fine. I can also run the self diag. on the system and it says everything is working fine.
Have you tried rebooting? In the Control Panel, select Sounds, select Speakers as default, remove headphones plug from jack.
Just FYI I have done this already and it still does the same thing. When running the self diag it shows the bar graph for the sound move up and down like it is playing audio, but nothing comes out. Under the config it says system operating properly. It's almost as if the speakers got unpluged or something like that.
OK, Perhaps your correct, the connection on the motherboard has come loose, or needs reseating. try some Electronic Contact Cleaner on the connection. You could always search ebay for speakers replacements.
okay, thanks for the help

SOURCE: Panasonic CF-51 Toughbook Fn keys don't work at all
The following website contains the needed drivers:
https://eww.pavc.panasonic.co.jp/pc/cgi-bin/itn/toughbook/dl01.cgi
Select your model of CF-51 Toughbook, but you MUST be specific. There are about nine variations of the CF-51 so you must use the right drivers.
Download the hkeyapp, hkeyset, and hotkey files and unpack all files. Use the default unpack locations. If you download the files for a laptop version that is not your own, when you try to run any of these files the computer will tell you that the file is not for your model. If the files successfully unpack then you know you have the right files.
For hkeyset and hkeyapp you must run the set-up applications in the unpacked folders.
Go to Control Panel>System>Hardware>Device Manager and go to Other Devices.
The Hotkeys will appear as an "Unknown Devices" so if there is more than one, right click and choose "Update Driver".
Select "Install driver from specific location" and direct it to "C:\util2\drivers\hotkey" folder.
The computer will find the file and install the driver after which point you must restart the computer.
Hope this helps. It took me a while to figure this stuff out on my own so hope it speeds up somebody else's attempt.

Hit "FN" and the "NUM Lock" key together to unlock it.
I believe thats the combination.
Let me know.
SOURCE: I used the FN + Mute button on my panasonic cf-w5
Double-click the "volume control" icon, to open the "sound mixer" control. Move all the sliders to "maximum", and remove any "mute" check-boxes.
Do you have a "FN + something" key to increase the volume?

When booted into windows just hit fn and f4 again. That should unmute it. You can also look at the toolbar at the bottowm right corner. You should see an icon that looks like a speaker. Right-click and check to see if mute is checked. If so just uncheck it.

click on Start / Control Panel / Sounds And Audio Devices
look at Speaker Settings / Advanced -- be sure it is set to your internal speakers.
the tabs across the top; go to Audio. -- be sure it is set to your sound card. For example, mine is "SoundMax Digital Audio" ... If there is another device you use that plugs into your USB, it could have stuck on "USB Codex". If it is, just put it on "NameOfSound Card" ...
Good luck, Don't be afraid to look all around inside the Sounds And Audio Devices box. And is this helped, please take a sec to rate me. Thanks!
