Lt4009u volume

Go into System Restore and recall the Operating System from an earlier date when the volume control worked properly. Select a known good date from a highlighted date on the back-up calendar and let i go backwards in time. It should repair it for you.

Instruction manual toshiba

I did a factory restore on my Toshiba because after I did a system restore to an earlier date it still was not working like before nor could it pick up any wireless signal. But I could and still can connect through ethernet cord. How do I get my laptop to pick up any wireless signal?

Side note: I have unplugged my modem and router for several minutes. Maybe like 15 min or so. Also turned off my laptop then plugged in modem, then router then turned on laptop....nothing still.

I have tried a few other things suggested on here but still nothing.

*I remember seeing on a screen that wireless was not enabled* I did try the "FN+F8" nothing.

I share a supported links, visit and follow instructions.

IBM Thinkpad A31P sound stopped working. Hdwe device manager shows no Audible Device Available. Troubleshooting indicates current drivers installed and working. Can I assume the audio chip is fried?

Not yet.
Check to see if the Mute has not been selected.
Check the volume level move the slider to a louder level.
Insert a headphone into the headphone socket to see if you can hear a sound.
If all these are done and you still do not hear sounds then you have a problem.
For a fix -
Then I suggest you get an USB audio stick, plug it into an USB port, install the driver and connect speakers to the USB audio stick.

The audio of my pc has lost how could i get it back

Make sure the volume is turned up or the mute is not checked on the audio menu. Or, try to 'restore' back to an earlier date when it did work for you.

Good luck on this.

I have an A105 Toshiba laptop. The sound stopped working suddenly. I restarted and all was well, then it quit and it now appears to be permanent despite restarts. The sound does not work through head...

HI there,

A great number of things may have occurred, but sometimes an update by any program you may have installed can cause conflicts. If this happened very recently, you might try System Restore back to an earlier time and be back to normal. If that's successful, beware of incoming updates which may try to replace themselves and don't allow them before Googleing o your laptop and this particular problem.

At least System Restore can cause you no harm and might fix the problem. So, do me a favor and don't trash my rating with a thumbs down if it doesn't work. Taking you through the entire range of troubleshooting for this problem would be no small task.

Best Wishes

CineDashMediaConsole.volume not working.

Cinedash FIX for Windows 7
This works to fix the CineDash Media Console!
I had the same problem with my Aspire 8920G
Now it works fine.
Getting the CineDash Media Console and Launch Buttons working
If you have problems with either the CineDash Media Console or Launch buttons then you will be happy to hear that the solution for fixing these is easy!
The first thing that you will need to do is install the “Launch Manager” which can be downloaded off the Acer website. Go to and click the service support, then driver download. Go to your model. Download the Launch Manager on the acer site. The filename should be “Kilimanjaro_v2.0.00_Vistax32×64_XPx32×” the version of Launch Manager under the Windows Vista operating system .This will get the Email, Web and Empowering Technology buttons working with their default settings. If you need to change what the buttons do, you can launch the application named “Launch Manager” in the start menu.
Uninstall any previous version of Launch Manager
The solution to my problem was to get the Launch Manager to run in compatibility mode for Windows Vista Service Pack 2.
Unzip. Explore the new folder and right-click Setup.exe.
To do this go to the Launch Manager Install directory (C:\Program Files\Launch Manager ), right-click on “setup.exe”, select the “troubleshoot compatibility” tab, check the “Troubleshoot program” check box and then click “The program worked in earlier versions of Windows but won’t install or run now”. Then select “Windows Vista Service Pack 2”. Then click “Start” program. Now everything should work properly! It will install. But don’t reboot yet!
Now locate and explore the freshly installed folder in your program files directory – (probably C:\Program Files (x86)\Launch Manager or C:\Program Files\Launch Manager depending on if you are running 64-bit or 32-bit)
right-click on “LManager.exe”, select the “troubleshoot compatibility” tab, check the “Troubleshoot program” check box and then click “The program worked in earlier versions of Windows but won’t install or run now”. Then select “Windows Vista Service Pack 2”. Then click “Start” program. Now everything should work properly! It will install.
Reboot and enjoy properly synced volume, and fully functioning buttons.
