1) With a laptop Robert, or all computer hardware in the world?
2) Since we are in the Laptop PC category, I'll assume a laptop.
We're getting closer
3) What is the laptop manufacturer name, and model number?
Model number is on Bottom of laptop.

4) What is the problem?
Post back in a -> Comment.
While I wait;
A) An LCD screen does not produce light. it needs an additional light source.
A Backlight is the additional light source.
A Backlight can be a CCFL, (Or more than one), or a series of LED's. (Light Emitting Diode)
A CCFL is a Cold Cathode Fluorescent Lamp.
Similar to Fluroescent lighting used in homes, and businesses; but on a MUCH smaller scale.
Average thickness is 2mm. That is a little more than 1/16th of an Inch, or about the width of this capital letter -> O <- .......
Average length is almost as long, as the LCD screen is in height.
View the last 8 photos,
B) A screen Inverter is used to convert the power (Electricity), from the laptop; for the LCD screen, and Backlight.
A screen Inverter IS used for CCFL backlighting. LED backlighting MAY, or MAY NOT use a screen Inverter.
General rule of thumb is LED backlighting DOES NOT. (First design systems used an Inverter on SOME laptops. Later designs do not seem to)
90 PERCENT of the time the fault can be attributed to a bad screen Inverter.
Average example of a screen Inverter,
(The plastic frame in front of the LCD screen, is the Display Bezel. Different manufacturers/different names. The screen Inverter is mounted at the bottom of the Screen Frame, and behind the Display Bezel.
The LCD screen is an assembly. It is composed of layers, and the layers are held in the factory set alignment, by a metal Screen Frame. Resembles a picture frame.

Most new devices your computer will recognise automatically. When your comp is running, plug in your new dvd player. Does it beep and say 'New Hardware added? If not then use
The Add Hardware Wizard which enables you to add new hardware or troubleshoot any hardware-related problems.
Open the Add Hardware Wizard

  • To open the Add Hardware Wizard, click Start, click Control Panel, and then click Printers and Other Hardware. Under See Also, click Add Hardware.
  • If it can't recognise the player, it gives you the option to select the correct make and model. Is yours on the list? If not, you may need to go to the Microsoft site and update the list of players.

How to get drivers


Below is a listing of different methods of locating and downloading drivers and software off of the Internet.
Determine the type of hardware
Before searching for the drivers or software of a device you will first need to make sure you know the manufacturer and model of the device you are trying to get software for. If you do not have this information you can find additional information about determining the type of hardware in your computer by reading document CH000494.
Alternatively if you are looking for software or drivers for the hardware device that is inside your computer and your computer is manufactured by an OEM such as Gateway or Dell you can often find the drivers for your computer using the manufacturers web page. You can find a listing of computer manufacturers here.
Download location
If the manufacturer of your hardware is still in business often the drivers will be listed on their web page. Computer Hoe has taken the time to link to each of the manufacturers driver pages on our drivers section. Visit this page and locate the manufacturer of your hardware device for drivers.
If your hardware manufacturer is not listed in our driver section we would of course appreciate you letting us know about it and then you can almost always use your favorite search engine to locate the drivers. Often searching for the model and/or manufacturer with the keywords "drivers" or "downloads" will find results for sites containing your driver. Additional information about finding information on the Internet can also be found on document CH000082.
If the manufacturer of your hardware device is out of business or the company who purchased the company who used to make your hardware device does not offer drivers for your product you can always use third-party companies who specialize in making available out-of-date or obsolete drivers available. You can find a listing of these sites on our driver links section.

No audio output device is installed, how do I put it in?? MAG monitor, Compace tower..

Depends on what operating system you are using. If you are using Windows Xp and above. You can try going into add remove hardware. Try adding a new hardware from list. When you can try reinstalling the windows audio driver. This has worked for me numerous times. Try this step
My computer
-Control panel ( use classic veiw)
-- Add Hardware
--- Click Yes
---- Scroll down to the bottom of the list and select add a new hardware device
----- install from a list 2nd option
------ click on sound video and game controllers
------- Try the Aztech systems and use the first option on the right hand window.
then click next until you are able to install it. It should work after that.
Best of Luck

New hardware might not work properly

Right guys, found the sollution:

Right click on My Computer, Choose Properties from the drop down list, then click on Device Manager.

Down the list, there will be Universal Serial Bus (USB) controlers. If this selection isnt expanded already, click on the + icon next to it.

In the list that pops down, there will be an entry called IPod and it will have a yellow question mark on it. Right click on this, choose properties and then click on update drivers. Follow the install wizard and then voila! It will be installed.

Have fun guys!

I lost the sound on my computer.

 Go into control panel and then goto system. From there go into hardware, then device manager. Scroll down to the Sound, Video and Game Controllers... See if your sound hardware is in there or if there is a yellow exclamation point on it. ( An explanation point states that the device is not working). I would try to remove it from the list and right click on the devices and let it scan for new hardware. With any luck it should re-identify the hardware and reinstall the drivers for that piece of hardware. If you have the audio drivers for your computer, you could try to reinstall the sound drivers. If you dont have the drivers then you should be able to download them off of the internet. 
 If your hardware is in the list and it appears to be working, double check your speakers and the speaker volume on the speaker itself as well as the volume control in the computer.                                                           Hope this helps...                                                                            Joe < Data Miner >

I have a Toshiba Laptop with Windows Vista and when I go to the speaker on the bottom right corner and click on it it shows a little red X that says no audio output device is installed. It was working fine...

To begin, let's open up the Device Manager. In Windows Vista, go to Start, Control Panel and click on the System and Maintenance link. Next, click on the System link and then on the left hand side under the Tasks pane, click on Device Manager. That will open a window that lists all of your computer's hardware. You'll see all of your computer's adapters, ROM drives, your keyboard, your mouse, the controllers, the USB ports, etc.
Now, let's get back to the question at hand. If you've been having trouble with the drivers for some of your computer's hardware, there are three common issues that come into play. Chances are, your problem lies within one of them, so let's get down to it!
1.) Certain Hardware is Not Listed - The first problem arises when hardware you expected to find is not listed. If something is left off the list, it's likely the hardware was not installed correctly. In that case, you should power down your computer and find the actual hardware device. Take some time to make sure it is hooked up correctly and then restart your computer. Once you do that, Vista should automatically recognize the hardware and it will go through the installation process again. You may be asked for the hardware's drivers during the new installation, so just make sure you have those ready to go as well. When the installation is done, you should now see the hardware listed under the Device Manager.
2.) You See a Yellow Exclamation Point - It's possible that when you get the Device Manager open, you'll see a few entries that have yellow exclamation points next to them. When that happens, it means the hardware is installed correctly and Windows recognizes it, but it's still not working properly. This type of thing usually involves a driver error, so you just need to update your drivers. To do that, right click on the hardware (the one that has the exclamation point next to it) and choose Properties. Next, click on the Driver tab and then the Update Driver button. From there, click on the option that says "Search automatically for updated driver software." Vista will then look for the correct updated drivers for your hardware device and install them for you. If Windows can't find any, you will need to go to the manufacturer's Web site and download them there.
3.) The Dreaded Red X Appears - If you have a hardware device with a red X next to it, you're dealing with a disabled piece of hardware. To fix that, simply right click on the hardware and choose Enable. That will start up the hardware and you can begin using it like normal once again.
That's it! Working through all of these troubleshooting techniques should fix your hardware issues within your Device Manager
