If your laptop has an external monitor VGA connector, try plugging it to a monitor and see... probably the screen in your laptop got damaged, or the graphic card portion of the laptops motherboard is dead.

Sorry, I don't know about prices, you'll have to visit a local PC/LAPTOP repair shop.

How do you fix a white screen for a dell Inspiron 1100 lap top?


White LCD screen in a Dell Inspiron 1100 Notebook PC?

1) Loose connection of the video cable TO the LCD screen, and/or loose connection of the video cable TO the motherboard.

2) Bad LCD screen

3) Bad motherboard. (More specifically a bad graphics chipset)

To start the diagnoses to find out what the problem is, you will require an external monitor.

This monitor can be a CRT monitor (Looks like a small TV), or a flat LCD screen monitor that has a VGA cable.
(A CRT monitor is a VGA monitor also)

Example of a VGA cable, and a VGA port, (Connector on computer),

http://en.wikipedia.org/wiki/VGA_connector

The VGA port is on the back of an Inspiron 1100 Notebook PC.
It is Blue in color.

A) Laptop OFF, monitor OFF. Connect the VGA cable of the external monitor, to the laptop's VGA connector (Port)

B) Turn the external monitor on. If a CRT style allow it warm up.
Turn the laptop on.

By default, (Factory setting), the external monitor should show the graphics of the laptop.

IF Not;
There are 3 options available,

1) Internal monitor of the laptop - ONLY
2) Internal monitor of the laptop, AND external monitor
3) External monitor - ONLY

If there is NO display on the external monitor, (Display; To include a white screen);

A) Press the Fn key, and hold it down. Now tap the F8 key. (F8,CRT/LCD)

Still no display on the external monitor? Press, and hold down on the Fn key, and tap the F8 key again.

IF, the external monitor shows a white screen, Stop.
You have a bad graphics chipset. Option is to replace the motherboard.

IF, the external monitor shows graphics just fine, diagnose further.

A) Look to see if the Video cable is plugged in tightly to the motherboard, AND connected tightly to the LCD screen.

Dell Support > Inspiron 1100 Notebook PC > Service Manual,

http://support.dell.com/support/edocs/systems/ins5100/en/sm/index.htm

Click on - Display
Under the heading - Display Assembly, look at the partial 'photo' under the number 8.

On the left side where it shows two Philips head screws removed, is the Video Cable. Pinkish wire wrapped around a Light Blue wire.
Look at Number 9.
The display-feed flex cable is the Video Cable.

Make sure it is plugged in tightly to the motherboard.

Now go down to Number 10.
In the exploded drawing the number 7 points to the Video Cable.
(display-feed flex cable)

Shows the Video Cable disconnected from the motherboard, and going up to the back of the LCD screen.

Scroll down to the heading - Display Panel. This shows the connection of the Video Cable to the LCD screen.

Also;
The Video Cable runs through the left Hinge Cover.
Repeated opening, and closing of the laptop, may have damaged the Video Cable.

Observe the sheath of the Video Cable. (Outside wrap)
Does it appear damaged? Pinched? Torn?
Even if it does not, I suggest performing a continuity test with a multimeter.

Multimeter's function knob is set to Ohm's. (Omega symbol)
Positive probe lead (Red) is touched to one end of a wire going through the Video Cable.
Negative probe lead (Black) is touched to the other end of the wire.

Do not be concerned at this time with the Ohmage. Concern is to see if ANY reading comes up, not how much.

Perform a continuity check on all wires in the Video Cable.
(An economical, yet decent enough multimeter for this test, can be purchased for around $5 to $12. A multitude of store carry them. An auto parts store is but one example)

Video cable checks out?
The next suspect is the LCD screen.
However, read on.

Primer:
An LCD screen does not produce enough light by itself. It needs an additional light source.
A Backlight is the additional light source.

A Backlight is a CCFL.
Cold Cathode Fluorescent Lamp.
Similar to Fluorescent lighting used in homes, and businesses, but on a MUCH smaller scale.

An Inverter (Screen Inverter) is used to convert the power (Electricity) from the laptop, for the LCD screen, and Inverter.

90 PERCENT OF THE TIME the fault is the Inverter.

Example of a screen inverter for a Dell Inspiron 1100 Notebook PC,

http://www.nylaptopparts.com/index.php?main_page=product_info&cPath=91_95_125&products_id=547

An expensive (Read - Sensitive) multimeter can be used to check a screen inverter. Not something everyone has laying around, or access to. In this case I would suggest replacing the Inverter.

(The screen Inverter is also easily accessed, AND much cheaper in comparison, than the LCD screen. Again, 90 percent of the time the fault is the Inverter )

IF, the Inverter does not cure the problem, then the problem is the LCD screen.

Review;
Check the display with an external monitor. Display checks good, run a continuity check on the Video Cable.
Video Cable checks out OK, go to the Inverter.
Inverter does not cure the problem, the problem is the LCD screen.

BEFORE beginning to disassemble;
Remove ALL power to the laptop. Remove the AC adapter (Charger), and Battery.

Observe Anti-Static Precautions.
(I would also advise using an ESD wrist strap, and connect it's alligator clip to a good ground source.

Average cost of a decent ESD wrist strap, is around $3 to $6.
I connect to an unpainted surface, of the metal frame of an open, empty desktop computer case.
{Electro Static Discharge)

Use a multi-compartment container for the various screws you will remove.
label each compartment for the area the screw/s come out of.
If no multi-compartment container is available, substitute with a clean egg carton.
Label each egg holder.

SOME screws look VERY similar to other screws.
Do Not mix them up.

For additional questions, or to have me explain anything I have stated here, post in a Comment.

One bad lead can cause a computer to continue on a cycle or to shutdown or fail to detect your hard drive

Test all leads that attach to your hard drive including electrical extensions,IDE,SATA

the leads from your ((motherboard to your hard drive)) make sure they have a secure connection and are not faulty or just replace them there probably old and faulty
make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty even the electic extensions or just replace them they are probably faulty a computer needs its connections to have an end so any faulty leads will end up with a computer error hope this helps

Ok here is my problem. I have an Acer Aspire 5536 and the graphics card is out. I need to know how I fix this problem(as in if I can get a new card or a new motherboard.) I love my laptop and my whole life...


Sorry to hear your having problems with your Laptop.

First thing we can try is to see if you can use an external monitor.

Use the (Blue) VGA connector on the side of your laptop and a VGA cable to connect it to the monitor. See Below.

greed03_3.jpg
Once you have your laptop connected to the external monitor, turn it on and see if it comes up on the external monitor.

If it doesn't, you might have to hold down the Function Key and press F8.
This will cycle between the laptop monitor and the external monitor.

greed03_14.png
If that works, it might be the laptop screen has probably gone bad.

If nothing still comes up on either screen, it's probably time to get a new Video Card or Motherboard.

If you still have questions, please send me a message and I'll see what i can do to help you further.

Hope this helps!

I want to upgrade my graphics performance for hp pavilion dv6


If this is laptop, In laptops the graphics cards are integrated meaning they are a part of the motherboard. There is no slot or place to put a card in, usually it is in a chip that is fused to the motherboard and the only way to get a new one is to replace the motherboard itself. Either try to play around with settings to get the most out of it or buy a new laptop. I would say upgrade your graphics drivers (nvidia website) and Direct X (microsoft website). Turn off all background tasks and services in your task bar when running games. And you can tweak the game settings within the games also, turn off shaders and keep screen resolution lower possibly.

External monitor connection problem


The problem is with the laptop. The femal VGA port is slodered to the motherboard. Once the laptop's MB has been removed you'll most likely find the solder holding the VGA in place is most likely cracked/loose. The fix would be to remove the old solider & apply new.
I can't guide you through disemble, its complex. I can include a site to help you with this.

Probably a driver issue. Try Windows Update and select custom. Maybe there is an updated driver available, or there could be a driver conflict (wrong driver installed). At worst, it could be an issue with your screen itself or possibly even the motherboard. But I doubt it. If you can't find anything there, try http://www.toshiba.com

It sounds like the power distribution circuit on your motherboard is shorting out your AC adaptor. The motherboard will need to be replaced or repaired.

My Dell Inspiron 5160 won t turn on


Hello viceaddict6,

That model is known for this problem and Dell is aware of it. I believe they will replace your motherboard and AC adapter free of charge. Tell them your problem with the lights, and that motherboard is most likely not getting the powere it needs.

Below is the information to contact them; they are open 24/7. The express code they are referring to is a sticker that is taped to the laptop. My personal experience with them is good, they usually have someone drive out or come by within the same day or next day and replace the hardware with a smile.

Technical Support
(Please have your Express Service Code ready when calling) 1-800-624-9896
