40 x 40 x 10 with a red wire and black wire which plug into the motherboard. Easy fix by removing the four screws and old fan, and replacing it with the new fan. If your new fan has 3 wires, clip the white wire and tape the end, and splice the old plug on the new red and black wire.

1) Laptop OFF, external display OFF, connect the external display to the laptop.

Turn the external display on.
Turn the laptop on.

There are at least THREE -> display options available.

1) Internal monitor of laptop ONLY'
2) Internal monitor of laptop and external display
3) External display ONLY

Hold the Fn key down, and tap on the F4 key once.
Still no?
Hold the Fn key down again, and tap once more on the F4 key.

http://h10032.www1.hp.com/ctg/Manual/c01035667.pdf

No internal monitor, and not external display also, means problems with the graphics chipset. May be one of the HP/Compaq models, that has problems with the graphics chipset overheating.

Due to a poor cooling design for the graphics chipset.
Graphics chipset repeatedly overheats, and softens the solder connections of the graphics chipset to motherboard.
(BGA surface mount)

Laptop is turned off, and cools down. Solder connections (Solder joints), re-solidify. This causes Cold solder joints.

Remedy in this case is to reflow the graphics chipset, and add more cooling surface, to the small metal plate attached to the Cooling Tube, that sits on the graphics chipset.

There are two Fan/Heatsink Assemblies offered. (Thermal Module)

1) One is for models that have UMA motherboards.

[ Unified Memory Architecture.
A fancy way of stating the graphics memory is part of the System Resources. The Processor and Ram Memory.
Two other terms used are Integrated Graphics, or OnBoard Graphics.

BING!

It's also used for the HP Pavilion dv2000 series, which DOES have a problem with graphics chipset cooling.

Look at the photo of the HP 430463-001, and at the Black round Fan Assembly.
Look to the left at the copper Cooling Tube. See that triangle shaped area that sticks out? This tiny surface area is what cools the graphics chipset.

SERIOUSLY inadequate!

(The Processor sits under that black square at the top, that has a smaller square hole in it. Four screws surround it.

What kind of fan (ventilator) do I need for abit motherboard IS7-V2


Not sure what fan you are referring to. The CPU usually comes with a fan. A 40mm case fan would be good for ventilating the case.

My mainboard can't on I touch on chipset VT8237R very hot. What can ido to repair this mainboard ?


Unless the motherboard is malfunctioning, I wouldn't really worry about it. If Asrock didn't put a heatsink on the chip you're touching, that means that the chip was meant to get that hot for the lifespan of the motherboard. If you're really anal about it, you can increase the cooling in your case by adding better fans, or even go liquid cooling and buy a waterblock for the chipset and cpu.

I have hp dv6100 laptop. There was a issue with laptop where sometimes screen was all vertical line. The PC was rebooted and it was OK for few days. Now all sudden, laptop doesn't boot at all and back...


It is a problem with the GPU.

(Graphics Processing Unit = Graphics Chip

http://en.wikipedia.org/wiki/GPU )

Hopefully it has just lifted up out of the BGA surface mount a little bit, resulting in bad connection/s, and not burned up.


To explain;

The HP Pavilion dv2000 series, dv6000 series, and dv9000 series Notebook PC's, have an issue with a poor cooling system design.

{The HP Pavilion dv6100 is part of the dv6000 series}


1) Cooling System; Specific description relating to the Pavilion dv6000 series.

The cooling system consists of the Cooling Fan, Heatsink, and Cooling Tube.


1a) Typical construction of a Heatsink is a plate of metal with tall, thin fins protruding from it.
The plate of metal absorbs heat from whatever object it is placed against.

The tall, thin fins absorb heat from the plate of metal, whereby the heat is radiated away through the fins.

If a fan is used along with the Heatsink, the air flow goes in-between the fins, and around the fins, and helps to dissipate the heat by carrying it away.
{Such as a Cooling Fan}

1b) The Cooling Fan is mounted in a surrounding cage, or Shroud. In the center of the Shroud, air is drawn in.
There is an opening on one side of the Shroud to let air pass through, which goes to the Heatsink.

1c) The Heatsink is mounted to one end of the Cooling Tube.
Both the Heatsink, and Cooling Tube are made of Copper.

The Cooling Tube is as the name applies, a Tube.
The Cooling Tube is capped off on both ends, and filled with Nitrogen Gas.
The gas helps transfer heat along the tube.

Away from the Heatsink, attached to the Cooling Tube, is a small metal plate. This plate is made of copper also.
This plate sits on top of the GPU, and draws heat away from it

A little further away from this GPU plate is another small copper plate.
This one sits on top of the CPU.

{NOTE*
Thermal Paste is ALWAYS applied to the top of the CPU, and GPU chipsets. The Thermal Paste helps transfer heat to the metal plates. It also fills tiny imperfections not visible to the human eye.

The imperfections create air pockets where the plate meets the top of the chipset. Air is an Insulator, Not a Conductor. Thermal Paste is a Conductor. It conducts heat very well.

When a Fan/Heatsink Assembly is removed, the top of the CPU, and GPU chipset, MUST be Thoroughly Cleaned. There cannot be any old thermal paste left behind.
New Thermal Paste is then Properly applied }



The size of the Fan, and it's cooling capacity is too small for the job.
The metal plates are too small for the job. Not enough area.
The cooling tube is also inadequate for the job.

This leads to overheating of the GPU, because the poor cooling design cannot keep up with transferring heat away from it, adequately.

The GPU is mounted to the motherboard in a BGA surface mount.

Ball Grid Array.
To explain a BGA surface mount we will use the mounting technology of the older Processors.

The older Processors have pins coming out of the bottom. These pins then insert down into socket holes in a processor socket.

With the BGA surface mount there are Solder Balls which take the place of the pins, on the GPU chipset.
On the motherboard there are small Copper Pads, which take the place of the socket holes in a processor socket.

The GPU is set into place with it's solder balls lining up on the copper pads.
Then a predetermined amount of heat is applied, and the solder balls melt, which solders them to the copper pads, which in turn solders the GPU to the motherboard.

When the GPU exceeds it's thermal limit, (Maximum operating temperature), the solder balls begin to melt again, resulting in a poor contact of the GPU to the copper pads on the motherboard.

This can result in what you are seeing with your Pavilion dv6100.

If it was just a thin line, and no Backlight, I would deduce it is the Inverter. 90 percent of the time the fault can be found to be the Inverter, not the Backlight.
(The Inverter provides power to the LCD screen, and the Backlight)

With your problem I tend to believe it's the GPU chipset.

I also tend to believe that due to the this, and the solution contained herein,

http://www.youtube.com/watch?v=bnkQNmKauEc

Just one of the methods to repair the problem, but I like the logic behind his method.
I would use a Heatgun instead, however.

Go to Page 68.

The cooling system of the Compaq Presario C700 Notebook PC, consists of a Cooling Fan, Heatsink, and Cooling Tube.

The copper Heatsink is attached to one end of the copper Cooling Tube.
The Heatsink is a rectangular object with tall, thin fins protruding out from it.

The Cooling Tube is made of copper, is made into a J shape, and is filled with Nitrogen.
The Cooling Tube has two copper metal plates attached along it.

One copper metal plate sits on top of the Processor, the other copper plate sits on top of the graphics chipset.

The Cooling Fan is inside a plastic shroud that forms a circle around the Fan, and has an opening on one side to draw air in.

The Cooling Fan draws air into the laptop, and the air is drawn into the Heatsink's fins, where it goes in-between the fins, and cools the Heatsink.

The Heatsink absorbs heat from the Cooling Tube, and the Cooling Tube absorbs heat from the copper metal plates, that are sitting on top of the Processor, and graphics chipset.

Heat goes from the Processor, and graphics chipset, to the copper metal plates, then to the Cooling Tube, then to the Heatsink, where the heat is then radiated away by the Heatsink's fins, and the air flow from the Cooling Fan.

Air drawn in also contains dust, dirt, and may contain hair, lint, and food crumbs.
This 'Gunk' will stop up the fins of the Heatsink, collect in the Cooling Fan's shroud, and on the Cooling Fan's blades, center hub, and inside the shroud.

This blocks the air flow. The cooling capacity drops tremendously, the Processor then overheats, and so does the graphics chipset.

When a Processor overheats, it turns off. (BIOS turns it off) This is a Fail Safe feature that is built-in, so that the Processor does not burn up.


Suggest you remove the cooling Fan, use Q-tips, and/or a small soft brush, (Makeup brush, small utility brush, small paint brush, etc.), and a can of compressed air for computers, and clean it.

{CAUTION! Use Short Bursts of air when cleaning the Fan. Squeeze the trigger in all the way, then let go fast! The Fan is only designed to spin so fast. Spinning it faster than it is designed for, can lead to premature failure of the Fan's bearings}

Suggest you also clean the Heatsink. This means you have to remove the Heatsink. It is on the bottom of the laptop, and the laptop has to be completely disassembled in order to access it.
Page 79.

BEFORE you begin:
Before you remove the Fan and the Heatsink;

1) ALL power removed from the laptop. Remove the AC adapter (Charger) and Battery.

2) Buy and wear an ESD wrist strap, and connect the alligator clip to a good ground source.
(For an example I connect to the metal frame of an empty desktop computer)
{Electro Static Discharge}

Your body contains Static electricity. Static WILL fry out (Short Circuit) the hardware components inside a computer.
The ESD wrist strap will relieve your body of Static, and keep your laptop safe.
A typical ESD wrist strap costs around $3 to $6.

This is an example of an ESD wrist strap,

http://www.costcentral.com/proddetail/Cables_Unlimited_Anti_Static_Wrist_Strap/ACC1400/10720671/froogle/


3) Use a multi-compartment container for the various screws you will remove. Mark each compartment for the area the screw/s come out of.
There may be as many as 60 screws, and 12 different types of screws.
DO NOT mix them up.

If a multi-compartment container is not available you can substitute with a clean egg carton, and mark each egg holder.

4) Make a record as you disassemble. Make notes, and drawings, use a camera or video cam if available. (Use good lighting)

DO NOT USE A VACUUM CLEANER to clean the Fan, or Heatsink!

5) Clean the bottom of the two copper plates on the Cooling Tube, and the top of the Processor, and graphics chipset.
Use a plastic scraper. I use an old thick credit card, for example.

Follow with Q-tips dipped in Isopropyl Alcohol. (Rubbing alcohol)
91 percent is best, but 70 percent will do. Advise against 50 percent. (It's 50 percent alcohol, and 50 percent water)

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

The top of the Processor, and the top of the graphics chipset, plus the bottom of the two copper plates MUST be perfectly spotlessly CLEAN.
Then apply a large peas size drop of Thermal Paste to the top of the Processor, and graphics chipset.
Reinstall the cleaned Heatsink.

Power passes through the laptop but the monitor is black


"Power passes through the laptop but the monitor is black"

I'll assume you mean the Indicator LED lights come on, and the Harddrive Activity LED light flashes.

[Not that you have tested the Voltage going to the Inverter, or Voltage coming out of the Inverter to the LCD screen]



1) Suggest you first test to see if the problem is the Inverter, or the graphics chipset on the motherboard.

Attach a VGA monitor to the VGA connector on the back of the laptop. (Laptop and monitor off)

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

Turn the VGA monitor on, allow it to 'Come to life'.
Turn the laptop on.

Press and hold down on the Fn key, then tap once on the F key that toggles the display over to an external monitor.

(Generally the F5 key. The display toggle key may have two symbols on it.
One is an icon of a laptop that is open, then there is a slash /, and an icon of a Monitor. (Rectangular outline)
Since you did not post the Model Name, and Model Number, I can only give you generic information)

No display? Tap the display toggle key again.

Display?
Chances are that you just have a bad Inverter.

An LCD screen cannot produce enough light by itself. It requires 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 in size.

[Typical example of a Backlight,

http://www.buy.com/prod/ccfl-backlight-lamp-toshiba-satellite-1805-s204-13-3-wxga/q/sellerid/23962916/loc/101/215969147.html ]

An Inverter is used to provide power to the LCD screen, and the Backlight.
An Inverter is small circuit board. Typically 3 to 5 inches long, and the width of a finger.

An Inverter is typically located behind the Display Bezel, and at the bottom of the LCD screen.
Attached with a screw, two screws, or tape.

90 PERCENT of the time the fault is the Inverter.

[Typical example of an Inverter,

2) IF the display does Not come on the external monitor.

Some models of laptops have a poor cooling system design for their GPU chipsets.
(Graphics Processing Unit. or slang term > graphics chipset)

The cooling system varies from laptop manufacturer to laptop manufacturer, and model to model, but typically;

A) Cooling Fan
B) Heatsink
C) Cooling Tube

Typical construction of a Heatsink is a plate of metal with tall, thin fins protruding from it.
The tall, thin fins absorb heat from the plate of metal.
The fins then radiate the heat away.

The Cooling Tube is attached on one end to the Heatsink. The Cooling Tube is normally filled with Nitrogen.
The other end of the Cooling Tube has a metal plate, or plates, attached to it.

The metal plate sits on top of the Processor's case. Some designs also have another metal plate, which sits on top of the graphics chipset.
Some do not.

The Cooling Tube absorbs heat from the Processor, and graphics chipset, then transfers the heat to the Heatsink.

The Cooling Fan draws air into the laptop through the Air Intake Duct, then flows air through, and around the fins of the Heatsink.

With some laptop cooling system designs, as mentioned above, there is no metal plate sitting on top of the graphics chipset.
The Processor, and graphics chipset are the two hardware components that put out the most heat.
If no metal plate is used to transfer heat away from the graphics chipset, the graphics chipset can overheat.

Other laptop cooling designs are inadequate in the cooling system provided, in relation to, if they do have a metal plate sitting on top of the graphics chipset.

The fan size, and/or the Heatsink's capability, are underrated in relation to taking care of both the Processor, and graphics chipset.

The Processor may receive adequate cooling, but the graphics chipset does not, and overheats.

If a Processor overheats, it turns off. (BIOS turns it off) This is so the Processor does not burn up.
Not so with a graphics chipset. It will overheat, and burn up.



Usually before the graphics chipset does burn up however, there is another process that happens.

The graphics chipset is mounted in a BGA surface mount, to the motherboard.

With the older Processors there were pins that came out of the bottom, and inserted down into socket holes in the processor socket.

With a BGA surface mount the chipset has solder balls in place of the pins.
The motherboard has matching copper pads.

The chipset is set into place on the motherboard's copper pads, then the chipset is heated until the solder balls melt.
This action solders the chipset to the motherboard.

If a graphics chipset becomes too hot, the solder begins to melt again.
The solder connections are now bad, and no graphics are displayed on the LCD screen.
Monitor is Black.

This is information on the problem above, in relation to the HP Pavilion dv2000 series, dv6000 series, dv9000 series, and a lot of other laptop computers.
Also a possible solution to repair.

(I would use a Heatgun instead)

Northbridge chipset overheating


A small heatsink fan might very well be enough to dispel the heat on the northbridge. If you can find a small heatsink/fan would be a better solution, but doubtful that you'll be able to mount it on the chip if it's not setup for one to begin with. Try the heatsink, and go grab a $5-$10 case fan to help with some airflow. If the Athlon itself is heating up, getting a better cooling fan/heatsink combo. Alternately there are some liquid coolers out there that would definitely keep you cool, but they can be a little cumbersome.
