No sound on Panasonic cf-c1, even though it shows sound. I'm running windows 7. I tried reinstalling my sound driver, but it didn't work.

Download all the drivers at once from 'Driver Bundles' at Panasonic's website below. Just pick your Model and the Operating System you have. They downloaded all together in a folder on my Desktop when I did it. I was struggling to get my sound to work before I stumbled across this easy fix. I just went to Device Manger and pointed the sound to that Desktop Folder. It picked up the driver by itself without pointing it to the sound driver in that folder, but just the folder. You can do the same thing with any other driver you are missing. I was so pleased it was that easy.

Have you tried a pair of headphones to see if you can get sound through them? if not then i suggest you do so, if you cant hear anything then it is almost certainly an issue with the built in sound card and these normally aren't repairable in laptops. with this in mind jump on ebay or something and get yourself a cheap usb soundcard around $10 or $15 it's alot cheaper then a new laptop

remember if it's helpful rate it, cheer's the tech team

SOURCE: cf-50 sound problem

You have an incorrect driver - sometimes several different drivers have to be tried to get sound to work. A utility called Driver Magician will detect and tell you what sound device you have, you can use it in free by telling it to register later and it will work to tell you the device name and manufacturer.

I recently tried a dual boot with Windows7/Ubuntu 9.10. I lost audio despite all efforts in both of those operating systems until I reinstalled XP.

Still I had no sound until I installed a correct HOTKEY driver off the panasonic web site. Apparently there is an important switching function by this driver (?!) that is required. BEWARE OF THIS!

My system: CF-51LCMDDBM Mk2ll

Have you check Device Manager and under sound, video and game controllers to see if you have any yellow ? marks next to anything. You would go to start-control panel-system-hardware-device manager.
If you have any yellow marks missing then you will need to find the driver for those.
It may be a codec that you need too.
Also Start/ control panel/ Sounds check that MUTE is not selected and that volume is UP.
Could be these drivers that you need Audio Output: Sound card Audio Codec: STAC9751 Compliant Standards: AC '97.
Check this site and make sure you have the complete model number, There are several different ones for your Cf51 that should look like this CF-51xxxxA/H/Qxx (mk1) . Some model numbers require that you have Sevice Pack 2 or SP2 for windows installed for the sound driver to work.

Need drivers on my panasonic lap top cf-c1 which runs on window 10

All drivers should already be provided in windows 10, but if there are any specific ones required then your only option is to try the Windows 8 drivers.

Cf-29 does not work anymore with my linksys. Ipad works with the linksys though.

On ALL older Panasonic Toughbooks the original
WIFI drivers were the original drivers which shipped
with the operating system.

These drivers usually have a date of 2003 or 2004.

There are NEWER WIFI drivers that work with the
latest routers (G or N). The new drivers have dates
of 2006 or 2007 for Windows XP and 2008 or 2009
or even later for Windows 7.

The CF29 MK1 used a WIFI "B" Adapter which is limited.
The MK2 used a WIFI "G" Adapter which will be easier
to update.

Panasonic CF29 usually used Intel Brand WIFI adapters
so drivers could usually be found at the link:

Hi, does the touch screen have drivers for windows 7 for toughbook cf-73

It seems Panasonic discontinued the CF-73 and there is no updated drivers to support Windows 7. Sorry.

Go to device manager and check the status of the sound card. Also install latest sound card drivers for Windows 7 if required.

On Startup of my Panasonic CF52, It shows the blue Panasonic screen, then the windows loading screen, then it goes into a bright gray colored screen. It doesnt do anything more. Tried to restart and hit F8...

This is usually a problem associated with NOD32 or Cisco software conflicting with drivers or other software. If you can get past the grey screen even once, uninstall the software and reboot. If you can't get past the grey screen at all, then you might have to completely reinstall windows :(.

I'd look for professional hands-on help in this case if you're not comfortable doing this.

You can download the XP drivers from the panasonic site. CF-51 got many flavors and be sure that your model numbers are at hand when you retrieve the factory installed drivers.

Delete all SigmaTel drivers from the registry hardware section. This would help reinstall the correct driver. The presence of these wrong registry values prevent successful installation of the factory drivers.

I have installed se7en, vista and XP successfully. The sound is really problematic since Dell and Gateway laptops use similar sound chips and offers drivers on the net... but they don't work at all. The Gateway driver seems to install perfectly from device manager report, but only the mic works & no sound.

What I do is install the factory provided drivers in XP compatible mode and then use windows update to download the latest SigmaTel drivers (se7en pre-beta). Windows got a more compatible driver but it can only install over the original since the chips cannot be recognized.
