Im using Toughbook CF53 and all of a sudden it began not working. I checked all the properties thru control panel and Fn + F4 keys everything looks fine. What could be the problem and can i get help how to fix it. Thanks in advance
I had a similar situation with my CF-53. Oddly, the speakers would not work, but headphones plugged into the port on the front of the laptop would. Could you verify that you get audio through the headphone port, please?

Hit "FN" and the "NUM Lock" key together to unlock it.
I believe thats the combination.
Let me know.

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.

SOURCE: Can't get the sound back
You need to press FN + F5 or F3 one or the other will turn sound back on
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?
SOURCE: i used the fn then f4 button to mute my panasonic cf-y7
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.

Hi solomon , I want to help you with your problem, but I need more information from you. Can you please add details in the comment box?
Is the machine switching on?
If so, what lights come on?
Is there any display at all?
If so, what does it say>
Thanks Penz. here is my answer to your questions:
Yes, very much its on only and all the movies are playing but no audio. And I have attached TV Tuner with my lap and all the TV channels i can view but without audio. In my lap, the power LED, battery lights are glowing in green. Nothing else on. And I am using Realtek High Defnition speaker as default. I checked all the properties nothing is in "Mute" mode.
Try removing all sound drivers and then reinstalling them.
Have you, by the way, tried all the solutions below?
