I have a Panasonic tough book cf-52 and my speakers just stopped working.  If I plug external speakers in they work fine.  I guess my speakers may be blown but wouldn't I hear them cracking?  Also,  this kind of computer is built to withstand almost anything and built to last.  I have a hard time believing the speakers are blown.  Is there anything I can do to check this?

Have you tried the Troubleshooter to see what it finds?

 

Open the Playing Audio troubleshooter by clicking the Start button 4f6cbd09-148c-4dd8-b1f2-48f232a2fd33_818, and then clicking Control Panel. In the search box, type troubleshooter, and then click Troubleshooting. Under Hardware and Sound, click Troubleshoot audio playback. 18abb370-ac1e-4b6b-b663-e028a75bf05b_48. If you're prompted for an administrator password or confirmation, type the password or provide confirmation.

 

Have you looked at the BIOS to see if there's a setting for internal speakers/sound or anything related to sound?

 

Try this too please if the above doesn't work:

 

Go to: this page and download: "Panasonic Common Components Application" and "Hotkey Appendix Application"

(and any other drivers you don't have / need / etc).

Both of the above mentioned ones after being downloaded and executed will dump setup files to:

C:\util2\pcommon
C:\util2\hkeyapp

Run the setup.exe in pcommon first as it doesn't require a restart, then run the setup.exe in hkeyapp. Once done, please restart the PC and give us an update.

Hi Chris,  I was unable to get to the troubleshooter that you mentioned above.  I went to the control panel and wasnt sure where to type that.  I tried it in search desktop but it didnt come up.  Please advise.  Thanks!

This should be easier than messing with the control panel. If you click start-type in troubleshoot or start typing it, windows will automatically start to fill it in. Click Troubleshooting up top. When it launches then click hardware and sound. Then from there, you can continue on. If you tried to do it using the control panel, as soon as you launch it, up top you will see a search box in the right corner. You would type troubleshoot in the search box.

Hi Chris,  I think you might think I have a different version of windows than I have.  I have XP.  This is probably why I am not seeing none of this.  If I click start I cant just type something I have to click on something first.

Ok since this is XP, have you checked the BIOS under the integrated peripherals section to see if it's enabled? Sorry for all the confusion, I was under the impression this was Windows 7.

 

Have you tried holding the ftn key down and pressing F4? Also try holding down the ftn key and keep pressing F6 to turn the volume up. If you can also provide the model version of the cf-52, I'll help you find the correct drivers.

 

**This is also from the Panasonic Support**

 


For Win XP / Windows 7:
1. Go into "device manager -> view device by connections -> ACPI based PC/ ACPI x86 -> Microsoft ACPI-Compliant System-> Hotkey Driver for Panasonic PC. Right click on it and remove it) DO NOT REBOOT YET
2. Go into Control Panel, "add/remove programs","Programs and Features" to verify that the two main programs needed to insure the hotkeys would work are installed. Those are the "Hotkey Appendix, and Hotkey Setting Application.
3. Uninstall The Hotkey Appendix, Settings programs , reboot the laptop only after the last program has been uninstalled
4. Upon reboot, at the Panasonic screen, press F2 to go into the BIOS and default the settings.
To default BIOS :
1. Reboot / power on the laptop and at the Panasonic screen, press the F2 key to enter the BIOS / Setup.
2. Once inside the BIOS / Setup, press F9. A window will appear asking if you want to "Load default configuration now?". Make sure "yes is highlighted and press the enter key
3. Now, press F10 and a window will appear asking if you want to "Save configuration changes and exit now?". Make sure "yes is highlighted and press the enter key.
5. When the laptop was rebooted back into the OS, reload the hotkey components in the following order...1. Hotkey Appendix**, 2. Hotkey Settings application. reboot the laptop after each components has been installed.
6, Manuever to the C:\UTIL folder and locate the below highlighted folders and run the executable.
Hotkey Appendix Utility
c:\util2\hkeyapp. Executing "setup.exe" .
After the program installs, reboot the laptop**.

Once back into the OS,

7. Manuever to the C:\UTIL folder and locate the below highlighted folders and run the executable.
Hotkey Setting Utility
c:\util2\hkeyset. Executing "setup.exe"
8. After the program installs, reboot the laptop, Once they have been reloaded, reboot the unit and then test the FN+F6 to see if the icon appears and then, check the sound.

**Hotkey Driver - This should install automatically once the Hotkey Appendix Utility is installed. If the sounds does ot work, then the Hotkey Drivers will have to be manually installed.

Ok Chris I didnt want to bother you with another crazy question because I have asked so many.  But my laptop only says cf-52.  I dont know how to find out what model version.  I tried googling to find out how so I wouldnt bother you with this but I had no success.  So I must ask.  Sorry!

yes thats all mine says cf-52.  Best computer I ever had.  I would have been through so many computers by now if I didnt have this.  I have spilled liquid all over my keyboard, dropped it, stepped on it (none of this was on purpose lol) and this thing has no problems until this.

That's the model # but there's also a model version that's different. You need it to get the appropriate drivers.

You may go here to get more information.

 

The "model version" or "full model number" starts with "CF-" followed by nine characters. The model version number is located at the bottom of the Toughbook unit in a grey rectangle

 

The sixth character in the model version number indicates "Mark" ("mk") or the iteration of the model due to hardware revisions during its life cycle.

This is hat I have.  I think the 9 charactors include the 52.  I have 2 rows although I think the first row of numbers is what you are looking for.  I will post both anyway.
