My Dell Inspiron 1545 lap top is not working. After switching on the laptop it is not doing any thing except glowing the LED. Even it's fan is not working. But LCD is working fine. I tested the LCD screen by performing the diagnosis process of dell laptop(by pressing D+Power button).

your LCD it toast its better to get it fixed. the cable only by-pass your lap top LCD thus allowint you to use your pc via another monitor sourse

Download and install the dell quick set software in your system according to the compatibility of windows installed in your system. you can even visit the website www.dell.co.in/support to get this software.

Okay, there's roll-over, play dead, and fetch.
[ Ziiiing! Okay fetch it dog! Ewww! That crunched it! ]

JUST KIDDIN'!

Tips:

A) The top of a Processor's case, and the bottom of the Heatsink that sits on it, are not perfectly smooth.

A magnified view would detail, 'Hills, Valleys, and Pitholes'.

When the two parts are mated together, these imperfections listed above, create air pockets.

Air is an Insulator, not a Conductor.

Thermal paste fills these voids, and is an excellent conductor of heat.
After time the thermal paste dries up. It looses it's thermal conductivity.

The top of the Processor, and bottom of the Heatsink, should be cleaned THOROUGHLY. Then new, fresh thermal paste applied.

ALL power removed from the laptop, (AC adapter {Charger} and Battery), you need to wear an ESD wrist strap, and have it's alligator clip attached to a good ground source.

This is what the Fan Assembly/Cooling Tube looks like,

http://www.ecrater.co.uk/p/13270427/dell-inspiron-1545-cpu-heatsink-cooling?keywords=dell+inspiron+1545+cooling+fan

Motherboard removed this is the side you will see.

At the top you see the Fan Assembly. (Fan inside a silvery shroud)
To the left of the Fan Assembly is the finned Heatsink.

Coming down from the Heatsink is the copper Cooling Tube.
Here you will see two metal plates attached to the Cooling Tube.

The first plate closest to the Fan Assembly sits on top of the Processor.
The next metal plate that is at the end of the Cooling Tube, sits on top of the G.P.U.

[Graphics Processing Unit. Slang? Graphics chipset ]

There are two views available. In the two views shown click on the bottom one.
This shows the Fan Assembly/Cooling Tube, upside down.

See the metal plate that sits on top of the Processor? Has four 'ears'?
The squarish copper plate in the middle, actually sits on top of the Processor.

The metal plate with the pointed tip to the right, sits on top of the GPU. The rectangular plate in the middle, actually sits on top of the GPU.

The top of the Processor, top of the GPU, and the two areas indicated above, need to be cleaned THOROUGHLY.
Use Q-tips dipped in Isopropyl Alcohol. (Rubbing alcohol)

I use 91 percent alcohol. 70 percent will do. Do Not recommend 50 percent. (It's 50 percent alcohol, and 50 percent WATER )

May take a few (Bunch?) of Q-tips. Sometimes it's a gooey mess.
DO NOT leave any old Thermal Paste residue behind. Clean enough to eat off of, is the motto.

CAUTION!!
Isopropyl Alcohol is EXTREMELY FLAMMABLE!
Use in a WELL ventilated area with NO sparks or flames present.

Laptop is overheating? Clean the inside of the laptop, (Especially between the fins of the Heatsink, fan blades, center hub of fan, and surrounding cage ), and clean, and apply new, fresh Thermal Paste.

B) No display on laptop's internal monitor? Use a VGA monitor, and connect it to the VGA connector on the laptop. (Laptop OFF, monitor OFF)
See if the display shows on the external VGA monitor.

(You may have to hold the Fn key down, and tap once on the F8 key.
Still no? Hold the Fn key down again, and tap again on the F8 key )

Display doesn't show you have a bad graphics chipset. (GPU)

Display does show on VGA external monitor, you have a problem with the Video Cable, and/or in the Display Assembly.

C) Laptops should be kept clean inside. Air is used to cool the hardware components.
Also do NOT block off the air intake duct on the bottom. Keep the laptop on a hard flat surface.
You may wish to also use a cooling pad. The fans create additional air for cooling.

90 PERCENT OF THE TIME the problem is the screen Inverter, and not the LCD screen.

[ Primer:
An LCD screen cannot produce light. It needs an additional light source,

http://solutions.3m.com/wps/portal/3M/en_US/Vikuiti1/BrandProducts/secondary/optics101/

A Backlight is the additional light source.
A Backlight can be a CCFL, or a series of LED's.
(Light Emitting Diode)

The Dell Inspiron 1545 Notebook PC uses has options of using either CCFL, or LED,

http://www.laptopscreen.com/English/model/Dell/INSPIRON~1545/

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

Average size is 2mm Thick. Length is almost as long, as the LCD screen is in height. 2mm is a little larger than 1/16th of an Inch ]

A screen Inverter is used to convert the power from the laptop, for the Backlight, and LCD screen.

ALL laptops that use a CCFL (Or two), for a Backlight, use a screen Inverter.
SOME laptops that use LED's for Backlighting, use a screen Inverter.
SOME do NOT.

Primer over.

That's off the top of my pointed head. Is there something specific you are looking for?

Try right clicking on the speaker icon in the right lower corner. This should open the sound properties settings for everything

try to detached first your battery of your laptop and insert it again for a couple of minutes.

Maybe it has full of dirt or with broken blade. Unscrew the bottom cover where your fan is placed then remove it. clean it or got o nearest computer repair shop to check it.

Dell.com are the only ones who may be able to help you.

The fan is failing mechanically - quite prematurely. There's nothing you can do - the fan must be replaced at a repair shop.

You have a bad or loose DC connector on the system board:

Symptoms of a broken power jack
1. If you wiggle the power cord or the AC Adapter connector on the back of the laptop, the power LED and battery charge LED start to flicker.
2. Battery will not charge in the laptop.
3. Laptop runs fine off a charged battery.
4. With the AC Adapter connected the laptop appears to be dead.
No power LED or battery charge LED activity.
5. Laptop randomly powers off without any warning.

If your laptop is out of warranty, then you can fix the problem by resoldering DC-IN jack on the system board. If it

The LCD is definitely shattered, looks like pressure was applied from the back of the screen (Pressed on, laid on etc) and the LCD will need to be replaced.
