Question about Panasonic Toughbook CF-27 Notebook

1 Answer

Alarm/Sound My Toughbook has started making a sound that I don't recognize. At first my power source was pulled out while the computer was on. When I turned it back on an alarm sounded then changed to a continuous "dotting" noise (like a machine gun) and will not stop. All files continue to function properly and I've turned off the alarm notifications and muted all sound, but the noise persists. ANY HELP???

This does not sound related, but I have seen this solve issues like this before.

Goto
Control Panel > Sounds and Audio Devices > Click the "Audio" tab > click the Volume button for your Sound Recording

Assure that Mic Boost is not turned on.

Let us know if you experience issues after this

I don't have the sound disk anymore and the monitor is not producing any sound. When I try to download the driver my computer says it doesn't recognize my model VA1930wm


The monitor driver is for your computer to recognize all the resolutions your monitor can handle, there is no sound driver for the monitor to work since the monitor built-in powered speakers are jsut that, powered speakers, same as the one you buy if the monitor does not have built-in powered speaker.
You can test the monitor speaker system by feeding it with the MP3 player or any sound sources.
It may have bad power amplifiers IC. You will be better off spending money on a good set of PC powered speaker system that will provide a lot better sound quality than the quarter-size speakers in the monitor.

Logitech speakers not working no sound


Turn off the speakers. Restart the computer with the speakers off. Once fully booted turn on the speakers. I had this problem where with the speakers on when the computer was started the sound card was not even recognized. Loading drivers had no affect. Good luck.

If the antitheft system is armed and isn't recognizing the key for starting, the dealer should be the next place it should be towed for reprogramming the key to the computer.

I installed windows xp pro and i have no sound cf-50 toughbook CF-50BB2NUDM I`ve tried Realtek and the panasonic sound driver download site nothing has worked so far.


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.

I HAVE A DELL OPTIPLEX 170L WITH BA735 SPEAKERS BUT i HAVE NO SOUND


Make sure you have a sound card installed
    • you think you have a sound card installed but you don’t see it under the Sound, video and game controllers category, expand the Other devices category and check any devices listed there.
  1. If there is a yellow question mark next to the name of the sound card, there might be a problem. Right-click the name of the sound card, and then click Properties.
  2. Make sure your speakers are plugged into a working power source and turned on.
  • Make sure your speakers are correctly connected to the computer.
    On your speakers, find the cable that plugs into your computer. Make sure that the speaker cable is plugged into the speakers and the correct jack on the computer. For example, if the cable is a 1/8 inch cable, there should be a round jack for it on the back of the computer. If it is a universal serial bus (USB) cable, it will plug into any USB port on your computer.
  • Make sure your headphones are not plugged into the line out (headphone) jack of your sound card or computer (unless you want to be listening with headphones rather than speakers). When you plug in headphones, most computers automatically cut the sound to the speakers.
If these steps don’t solve the problem, check the information that came with your computer and speakers or go to the manufacturer's website.

SimpleTech 320GB Hard Drive- unable to detect the device


I had a similar problem with a SimpleTech 250g Pininfarina USB drive.
I went through the drivers, the power supply, the USB cables, and the various
computers, USB cards and Operating systems.
Finally I opened the case and found the disk drive was mounted too far
forward, causing the IDE connector to barely touch. I loosened the mount screws,
slid the drive back towards the connector, tightened everything down and it works.
