SOURCE: problem in webcam

Try a msn or aol messenger, and enable the video option, your cam needs a program in order to run. Turning it on or off will not show if it works or doesn't, windows will use a default driver an it should work out of the box. If not go into your device manager, Start , control panel, device manager, hardware, web cam, and delete it. When you restart windows, it will find the cam and install the proper driver. If it still dosen't work then you need a driver, but it is in there trust me

SOURCE: Dell inspiron 1545 laptop and the same webcam problem.

open your my computer, click on "c" the system will tell you the information is hidden, click on the link and open up the operating system and look in the drivers or there in C and se if you can find you web cam driver, when you find it you might have to force the opening of the driver to install, and once you do that plug your web cam in and see if the system see's it and installs the drivers for the cam, if you installed the driver origanally witht he web cam installed you will have to remove the web cam and unistall the driver and re install it and then plug the web cam back in, and that should help correct the problem.

Dell l702x 17 motherboard

The chipset in reference is a graphics chipset.
Allow me to digress for a moment, and bring you up on a few basic things, so you know what we are talking about;

1) Chip and Chipset are slang terms for I.C.
Integrated Circuit,

2) The chipset, or Integrated Circuit for graphics; is a graphics chipset.
Proper term is G.P.U.
Graphics Processing Unit,

Upon reading the article, you will learn that the GPU can be mounted directly TO the motherboard, or mounted on a separate graphics adapter card.

You are probably familiar with the last term.
It's a graphics card. Also can be stated as video card.

Doesn't quite work that way in all laptops, or can be said, all laptop manufacturers.
Best way to sell a laptop? Make it seem better than it is.
Stiff competition.
Use the fuzzy definition of Graphics Card, and make the laptop seem better than it is.

Going back to the term GPU. The graphics processing unit, is actually the little chipset in the middle. Around it is a small circuit board.
The circuit board is an interface used to connect the GPU, to the motherboard, OR graphics adapter card. -> Such as used in a desktop computer.

Laptops usually have Integrated Graphics.
Means it borrows from the System Resources. The Processor, and Ram Memory.
This means the Processor, and Ram Memory are overloaded, when an intensive program is run. Such as an intensive game, for example.

An actual graphics card has it's own Processor. The GPU. But, it also has it's own graphics memory. Means it does not borrow from the System Resources.
Makes the laptop perform better. Also makes it sell better.
See why laptop manufacturers want to 'fudge', the graphics that is REALLY installed?

It IS a graphics card, but it is mounted to the motherboard with a BGA surface mount. This makes it TOUGH to replace, therefore tough to upgrade. Not really a graphics card IMHO.

From what I can gather looking at the specifications, for the
Dell XPS 17 Model L702x, it can come with a separate graphics card, or the GPU is mounted to the motherboard. (Integrated Graphics )

If it is mounted to the motherboard, it is Integrated Graphics.
IF so, the GPU is an Intel HD graphics. The GPU is built into the Processor itself.

If it is a separate graphics card, it is an Nvidia GeForce GT 550M,
OR, an Nvidia GeForce GT 555M. (Two options were offered)
M stands for Mobile.
It is a graphics chipset built for a Mobile computer.
Which a laptop is.
It is Mobile because you can carry it around.

According to what you have stated, from what you have been told, the motherboard needs to be replaced.

This means to me we are dealing with Integrated Graphics, whereby the GPU is soldered directly to the motherboard.
(Not a separate, thereby replaceable, graphics card)

The mounting for the GPU, or graphics chipset, is a BGA surface mount.
Ball Grid Array.

To explain the BGA surface mount;
Compare to an older Intel Pentium 4 processor, that uses a Socket 478 processor socket.
I do not know if you are familiar with this. If so disregard the following;

The processor has contact pins on the bottom. 478 of 'em.
The processor socket has matching socket holes,

Now to go on;
With a BGA surface mount there are no contact pins, nor socket holes.

In place of the contact pins are Solder Balls.
In place of the socket holes are Copper Pads.
The Copper Pads are mounted directly to the motherboard, (Simple explanation), and gold plated.

The graphics chipset is set down on the motherboard, with the Solder Balls lining up on the Copper Pads.
Heat is applied at a specific temperature, and length of time.

This action melts the Solder Balls, and solders the graphics chipset TO the Copper Pads.
(Which in turn, of course, solders the graphics chipset TO the motherboard)

If the cooling system area for the graphics chipset is inadequate, the graphics chipset overheats.
Constant, repeated, overheating can cause the solder connections that were made, to partially melt.

When the laptop is turned off, the solder connections re-solidify.
This causes a Cold solder joint, or solder joints.
(The solder connection is a solder joint)

This cause a poor contact of the graphics chipset to the motherboard, and apparently what you are seeing.

I state apparently, because -> I do not have the laptop in front of me, and have not diagnosed the problem. Going by what you have stated, from what you have been told.

From the specifications I have seen so far, I see a touchscreen can be an option. Do I assume your laptop does Not have this option?
Post back in a Comment.

Now I would like to show you a BGA Rework Machine (Station), at work. Gives you more of an idea of what a chipset is, and the BGA surface mount,

Scroll the page down, and click on the Red ->
Take a few minutes to view the IR 650 demo video

A 5 minute video.

This is an example of the CPU Heatsink, used to cool the Processor, and graphics chipset.
(Digressing; CPU = Central Processing Unit. Another term used is Microprocessor, or Processor for short),

Click on the image to enlarge.

You are looking at a Top view.

1) At the Top is a rectangular copper finned Heatsink.
It has thin pieces of a foam material that are black, on it.
(A type of Filter)

2) Coming away towards the right, you see two Cooling Tubes.
Slightly flattened copper tubes that are sealed on both ends, and filled with Nitrogen.

3) The first Large aluminum looking plate of metal at the Top, sits on the Processor. Two Philips head screws.
4) The rectangular shaped plate of metal at the bottom, sits on the graphics chipset.

The Fan Assembly is not shown. This is an example of it,

(Scroll down)
Left side is the Bottom, that sits on the motherboard. Right side is the Top.
The Fan sits next to the rectangular copper finned Heatsink.

Heat from the Processor, and heat from the graphics chipset, si absorbed by their respective metal plates. The heat is then absorbed by the Cooling Tubes. The Cooling Tubes transfer the heat to the finned Heatsink.

The Heatsink absorbs the heat, then radiates it away with the thin fins. Air flow from the Fan Assembly helps carry heat away from the fins of the Heatsink.

That rectangular metal plate sitting on top of the graphics chipset, is TOO small in surface area. The surface area needs to be increased.
How? Here is one tech's idea. It has been around a long time, just showing you an example. This is towards certain HP laptops.
(Not advertising for this guy, or his company),
