As Eblackadder says, you probably need a new board, but since that's the case you can take the attitude that you have nothing to lose.

If it were me, I would look very carefully at the motherboard around the socket to see if you can drill some small holes without hitting a metal trace. You will really be gambling here because these boards have metal traces embedded inside the board that you may not be able to see.

Assuming you can find a few spots where you think drilling a small hole is possible you could then use zip ties to pull the heatsink assembly down tight to the processor. I would use very small zip ties. Since these are typically not very long, you can chain a number of them together.

Best of luck.

Probably need a new board. If you try to start the pc without the heatsink tied down really tightly to the cpu, it will burn out the cpu in seconds. I think the part you are referring to is part of the built in cpu socket. Don't think it is removable.

Remove fan d865perl


It depends. You usually must replace the entire heatsink/fan assembly. If you have the standard 'Intel' heatsink/fan that came with a retail boxed Intel processor, you flip the levers in opposite directions to loosen the assembly, and then you slip a thin piece of metal under each of the four hooks that attach it to the mobo, but you do them one at a time. You just pry a little bit and lift up on each one. After the last hook is freed, you pull the unit completely off the board.

There's also a power connector. Don't forget to unplug it. There are at least 100 different styles of HSF for that mobo. You also want to twist a little to work the thermal-transfer compound loose. Otherwise you might pull the processor out with the HSF.

Screen wont light up


wafy_m, the problem can be attributed to the graphics chipset, is lifting off of the motherboard.
The mounting has loosened.

This is because the cooling system for the graphics chipset, is inadequate.

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

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

The graphics chipset is the GPU,

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

The mounting of the GPU to the motherboard, is done with a BGA surface mount,

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

To explain a BGA surface mount, compare to an older Intel Pentium 4 processor, that uses a Socket 478 processor socket,

http://en.wikipedia.org/wiki/Socket_478

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

With a BGA surface mount there are no contact pins, nor socket holes.

In place of the contact pins there are Solder Balls.
In place of the socket holes there are Copper Pads.
(Which have a gold plating on them)

The graphics chipset is set into place over the motherboard, with it's Solder Balls lining up on the motherboard's matching Copper Pads.

Heat is then applied at a specific temperature, and length of time.
The Solder Balls melt, which solders the graphics chipset to the Copper Pads.
(Which in turn solders the graphics chipset to the motherboard)

With the inadequate cooling for the graphics chipset, after time the solder connections will begin to partially melt.

This leads to a poor contact of the graphics chipset to the motherboard, and the problem you are having.

As previously stated the cooling system for the graphics chipset, is inadequate.

Cooling System:
The cooling system consists of a Cooling Tube, Heatsink, and Fan Assembly.

The Cooling Tube is a slightly flattened copper tube, filled with Nitrogen, and sealed on both ends.

Towards one end of the tube is an aluminum plate. This plate sits on top of the Processor. Has four screws through it. Removing these screws removes the cooling system assembly.

Coming up the tube a little bit, is another aluminum plate. This one is smaller, and sits on top of the graphics chipset.

Connected at the opposite end is the Heatsink.
The Heatsink is a small thin piece of metal, with Tall, Thin, fins protruding from it.

Next to the Heatsink is the Fan Assembly.
The Fan Assembly, is a Fan inside of a cage, or shroud.

Draws air up from the bottom of the laptop, and pushes it through the Heatsink's fins, and out the side of the laptop.

Heat from the graphics chipset, and the Processor, are absorbed by their metal plates.
The Cooling Tube absorbs heat from the two aluminum metal plates.

The Cooling Tube transfers the heat along up to the Heatsink.
The Heatsink absorbs the heat, then radiates it away with the Tall, Thin fins.

Airflow from the Fan Assembly, helps to carry heat away from the fins of the Heatsink.

The surface area of the metal plate on top of the graphics chipset, is too small. It is inadequate in surface area size.

The one on the Processor is barely adequate.

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

The above is posted for reference. Pause the video at 7:43 to see the cooling system I described above.

1) Black Fan Assembly to the upper left.

2) To the immediate left side of the Fan Assembly is the Heatsink.
Black in color, slightly rounded outside edge, goes along the full length of the left side of the Fan Assembly. Hard to discern the fins.

3) The aluminum X shaped piece with 4 black screws in it, on the copper Cooling Tube, is the metal plate for the Processor.

4) Coming up the copper Cooling Tube towards the Fan Assembly, is the second aluminum metal plate. It is shaped sort of like an S, with flat ends. This plate sits on top of the graphics chipset.

Solution?
Properly remelt the solder connections of the graphics chipset, to the copper pads.
Add surface area to the Processor's metal plate, and the graphics chipset's metal plate.

PROPER method is to use a BGA Rework Machine. Performed by a shop who has one.

ANY other method may is less than. The procedure may last a week, a month, or maybe longer.

There was a recall on this series of Notebook PC.

My computer fan wont turn off


That is because;

1) The inside of the computer is dirty. As such the cooling capacity has dropped. The Fan Assembly is trying to keep up with the call for cooling, and has to stay constantly on.

OR,

2) The laptop is suffering from an 'ailment', that is common for the Pavilion dv2000 series, dv6000 series, and dv9000 series of aNotebook PC's.

Specifically the cooling for the graphics chipset. It is INADEQUATE.

This leads to the graphics chipset overheating, and loosening the connection of the graphics chipset, to the motherboard.

To explain;

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

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

2) The Chipset responsible for handling graphics, is the graphics chipset, or also known as the GPU,

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

[ The Graphics Processing Unit for the Pavilion dv6500Z Notebook PC, is an Nvidia GeForce 8400M GS,

http://en.wikipedia.org/wiki/Comparison_of_Nvidia_graphics_processing_units#GeForce_8M_.288xxxM.29_series

It is Integrated Graphics. The GPU is soldered to the motherboard ]

3) The Nvidia GeForce 8400M GS graphics chipset, is mounted to the motherboard with a BGA surface mount.

To explain the BGA surface mount;
Compare to the older Intel Pentium 4 processors, that use a Socket 478 processor socket.

The bottom of the processor has 478 contact pins.
These line up with 478 socket holes in the Socket 478 processor socket,

http://en.wikipedia.org/wiki/Socket_478

With a BGA surface mount, there are No contact pins on the bottom of the chipset, nor socket holes on the motherboard. (No socket)

In place of the contact pins there are Solder Balls.
In place of the socket holes there are Copper Pads.

The chipset is set into place over the motherboard, with it's Solder Balls lining up with the matching Copper Pads, on the motherboard.

Heat is then applied at a specific temperature, and length of time.
The solder balls melt, which in turn solders the chipset TO the copper pads.
(Solders the chipset to the motherboard)

With the inadequate cooling for the graphics chipset, the graphics chipset constantly overheats.
In due time the solder connections start to melt.

This creates a poor contact, of the graphics chipset to the motherboard.

Explanation of the cooling system, for a Pavilion dv6000 series of Notebook PC:

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

A) The Cooling Tube is a slightly flattened copper tube, sealed on both ends, and filled with Nitrogen.

At one end it has a small metal plate.
One part of the metal plate sits on top of the Processor, and the other part sits on top of the graphics chipset.

The small metal plate AREA for the graphics chipset is TOO small.

Heat is absorbed by the small metal plate. The heat is then absorbed by the Cooling Tube.

At the opposite end of the Cooling Tube, is the Heatsink.
The Heatsink is a small piece of metal, with Tall, Thin fins, protruding from it.

The Heatsink absorbs heat from the Cooling Tube, and radiates the heat away with the Tall, Thin fins.

Air flow from the Fan Assembly, helps to carry heat away from the fins.

http://www.insidemylaptop.com/disassemble-hp-pavilion-dv6-laptop/

Drop down to Step 28. Here you are looking at a top view of the motherboard, and a top view of the Fan Assembly, to the upper left of the motherboard.

Go to Step 29.
This photo shows the bottom of the motherboard, and the cooling system.

Fan Assembly (Black),

Heatsink, (To the immediate right of the Fan Assembly. Black in color.

Replacemother board dv 8000 hp lap top and trunall ligths trun on but blac k screen.


I'm going to assume it was yourself, or someone besides a tech, who installed this motherboard.
A tech would have the machine working before giving it back.

A) What was the original problem? Why motherboard replacement?

B) Do you know for a fact that the replacement motherboard is a good working unit?
Bought from a reputable dealer, or history of motherboard is known?

C) Did you follow Anti-Static Precautions, and used a ESD wrist strap, and connected it's alligator clip to a good ground source?

D) How acquainted are you with the design of a laptop's cooling system?
Aware of the basic design?

1) Air is drawn in for the cooling system usually from the Bottom of the laptop.
(Air Intake Duct. It is expelled through the Exhaust Port)

2) The air is drawn straight up into the cooling Fan.
Air then is pushed through the fins of the Heatsink

There is a Cooling Tube usually made of Aluminum or Copper. One end is attached to the finned Heatsink.
The other end is usually attached to a small metal plate.
This metal plate sits on top of the Processor.

Heat from the Processor is absorbed by the small plate. The heat is then transferred to the Cooling Tube. (Cooling Tube absorbs heat from the small plate)

The Cooling Tube then transfers the heat to the Heatsink.
The Heatsink absorbs the heat, then radiates it away with the tall, thin fins.
Air going through the fins, and around the fins, helps to carry the heat away.

Also on the same end as the Processor, is usually another small metal plate. This plate sits on top of the GPU.
Graphics Processing Unit, or simply stated as the graphics chipset.
(Essentially the 'Graphics Engine')

The Processor, and the GPU, are the TWO hardware components that PRODUCE the most HEAT.


Example of basic laptop cooling design I referred to above,

http://www.insidemylaptop.com/disassemble-hp-pavilion-dv6-laptop/

Scroll down to Step 29.
Here you see the black Fan Assembly.
To the immediate left of it is the finned Heatsink. Black in color, fins are not visible.

Coming down on the left from the Heatsink is a copper Cooling Tube.
Most of it's length is attached to an aluminum plate.
(Three machine screws hold the plate to the motherboard)

The aluminum plate you see is covering the top of the Processor, and also the GPU sitting next to it.

Point?
In looking at the Heatsink/Fan/Cooling Tube combination, for the HP Pavilion dv8000 series of Notebook PC's, I do not see a metal plate for the GPU.

I only see that the Processor is covered by a metal plate.

Examples;

1) http://www.pchub.com/uph/laptop/423-55686-4713/HP-Pavilion-dv8000-Series-Cooling-Heatsink.html

2) http://cgi.ebay.com/HP-DV8000-8100-8200-Heatsink-Fan-Assembly-403826-001_W0QQitemZ280451159745QQcmdZViewItemQQptZLH_DefaultDomain_0

Heatsink with copper Cooling Tube attached, and small metal plate at the end for the Processor,

3) http://www.laptoppartsexpert.com/i-5846952-cpu-heatsink.html

4) Motherboard,

http://www.global-motherboard.co.uk/hp-motherboard/HP-Pavilion-DV8000-Motherboard-403835-001.html

This means there is no cooling for the GPU, except for air that may make it's way around, in the inside of the laptop.

Point?

A GPU is mounted to the motherboard with a BGA Surface Mount.
Ball Grid Array.

To explain a BGA surface mount;

Your motherboard has an AMD processor socket (Mobile) that an AMD processor fits in.
The socket has the socket holes, and the Processor has the contact pins, which go into the socket holes.

With a BGA surface mount there are no contact pins, or socket holes.
There are Copper Pads, and Solder Balls,

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

The bottom of the GPU chipset has Solder Balls.
The surface of the motherboard has matching Copper Pads.

The GPU is set into place with the Solder Balls lining up, to the matching Copper Pads on the motherboard.

Heat is then applied at a certain specific temperature, and length of time.
The Solder Balls melt, which solders the GPU to the motherboard.
(Solders the GPU to the Copper Pads on the motherboard)

IF, a GPU constantly overheats, the solder connections start to melt. This creates cold solder joints, and a black display on the laptop's internal monitor.

To summarize;

A) The motherboard that has been installed may have the same problem as the original one, if the problem was poor contact for the GPU.

B) If you did not follow Anti-Static Precautions, there's a good chance the motherboard is now an expensive paperweight, or doorstop.

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,

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.

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.

The Nvidia GeForce 8600M GT chipset isn't the problem. It's the cooling system.

The cooling system is inadequate. It cannot cool the Processor, AND the Nvidia GeForce 8600M GT chipset properly.

HP knows this.

When the Nvidia GeForce 8600M GT chipset overheats, it comes loose from it's motherboard mounting.

The method of mounting the 8600M GT is connected in a BGA mount.
Ball Grid Array.

To explain:
A) Chip and Chipset are slang terms for I.C. Integrated Circuit.

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

B) GPU = Graphics Processing Unit

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

The GPU is mounted on a small circuit board, and then the circuit board has a method of mounting to the motherboard.

With a Processor, the chipset is also mounted on a small circuit board. On the bottom of the circuit board are pins. These pins go down into socket holes in the processor socket.
(Or you have Processors with the socket holes, and the processor socket has the pins)

Instead of pins for mounting, there are round solder balls on the bottom of the small circuit board.
On the motherboard area that the circuit board is to be mounted to, there are a matching number of copper pads.
(We are talking REAL SMALL here. Copper pads about the size of a straight pin head, solder balls about twice the size of this period >. )

The circuit board with it's solder balls, is set into position on the motherboard with it's copper pads.
Heat is used to melt the solder balls, and they solder to the copper pads.

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

The cooling system in the HP Pavilion dv9700t Notebook PC (Laptop) consists of a Fan/Heatsink Assembly.

The fan draws air up from the bottom, and pushes air through the fins of the Heatsink.
The Heatsink is attached to a long copper tube.
The copper tube has two flat copper plates on it.

One copper plate sits on top of the Processor's case.
The other copper plate sits on top the GPU chip.

Heat is drawn from the Processor, and from the GPU chip to the copper plates. The heat is then transferred to the copper tube, and then to the Heatsink.

It's a POOR design.

Thermal Paste.

The top of a Processor's case, and the bottom of a Heatsink are not perfectly smooth. A microscopic view would reveal, 'Hills, Valleys, and Pits'.
These imperfections create a void when the two surfaces meet, and Air pockets are created.

Air is an Insulator, Not a Conductor.

Thermal Paste is a Conductor. It helps to conduct heat from the top of the Processor, to the bottom of the Heatsink. It also fills those voids.

[ Typical construction of a Heatsink, is a plate of metal with tall, thin fins protruding from it.
The plate of metal is placed against whatever object needs to have heat transferred away,
(Processor in this case), and the tall, thin fins absorb the heat from the plate.

The tall, thin fins then radiate the heat away.
If a fan is used along with the Heatsink, the air flow helps carry heat away from the fins ]

The Satellite P100 series of laptops, (Includes the P105-s6104), have to be disassembled down to the motherboard, in order to access the cooling assembly.

In the Satellite P100 series of laptops, the Heatsink is usually attached to a Cooling Tube. The Cooling Tube attached to flat plates that sit on top of the Processor, and on top of the VGA chipset.

The Cooling Fan sits on top of the Heatsink.

The VGA chipset's circuit board is soldered to the motherboard. It isn't removable like the Processor.
Overheating may cause the solder joints to loosen enough, that the circuit board connections, (BGA), may come loose. This causes the VGA chipset to slightly lift up out of the motherboard connections. This can cause graphics problems. A special method is used to remelt the solder connections of the BGA, and the circuit board is put back in place. (Reflow)

Hopefully cleaning, and applying fresh new thermal paste to the Processor, and VGA chipset will solve your problem. Reflowing is usually done by the factory, although there are repair shops with the expertise, and correct machines. (Ka-Ching!) Most computer repair shops do not have the correct machines, nor the expertise.

REMEMBER!
All power removed from the laptop. AC adapter (Charger), and Battery.
Use an ESD wrist strap, connect the alligator clip to a good ground source. (Average cost is $3 to $8)
Use a multi-compartment container for the various screws you will remove, label the compartments for where the screws came out of.
There may be as a many as 60 screws, and 12 different types. Do NOT mix them up.
(You can use a clean egg container in a pinch. Label each egg holder)
