Cooling vent on motherboard fell off

The cooling vent came off of my motherboard. I think this is the model number? I found this plate on the board. Does it look right to you?


I also think my power supply may be bad. I've ordered a replacement atx-250-12z.
Nothing happens when I try to turn the computer on though the green light in back is flashing. From other answers I've seen on this site that leads me to believe I need a new one.
As to the vent, can I just glue it back on? Please tell me I don't need a new motherboard.

The mother board is hot

Possible cooling fan problem.make sure the vent ports are clear of lint,dust not use compressed air to blow out vents,,often this will blow debri directly into the hard drive use a Q-tip....cooling pads or 15 dollar cooling stands may keep it cool until you find someone to take it apart and see if the fans or fan is bad.

I have a Dometic fridge model number RM2612 in a camper that i just purchased used and the fridge isn't cooling. The freezer section seems to be okay. The metal plate in the freezer gets cold but

Make sure it is level, has proper airflow out through top vent. Also check baffle, or stack where flame sits under and blow it out good with compressed air to make sure it's clean. If you smell a hint or strong smell of ammonia, shut it off, it has a leak in cooling unit. If all ok in that area, shut it off, disconnect and plug propane line, disconnect power and remove the fridge. Turn the fridge upside down for a day or 2, then re-install and let it sit 24 hrs before turning it back on. Quite often that will take care of any blockage in flow of cooling liquid, and get things back to normal if cooling unit is still good.

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,

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.

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.




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


4) Motherboard,

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.


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,

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.

Not cooling enough on frigerator side but it still works on freezer side.

Hello Mjorgy,

I understand that you are having a problem with you refrigerator. The freezer is cooling fine, however the fridge side is not cooling enough. This is a common problem with the evaporator coil stops working. When you open the fridge or freezer you should hear a fan running or fell are coming out of the vents to the fridge.

I would love to help you further if you can please post a model number for the unit I will look up where the fan is located and let you know how to get to it in step by step instructions. You should be able to locate the model number in side the compartments on the wall close to the front. It is also located on the rear of the unit. Please post back to this thread so that I may assist you further.

Thank you for choosing

Unfortunately HP has has an overheating problem with their laptops for years. Machines often get hot enough to melt the solder and other parts on the motherboard . This often results in faults ranging from system shutdown to audio problems to complete failure. They have not addressed this issue adequately.

It would be best to replace any parts that show heat damage. You can verify that the fan is working by hearing it run. Also your bios should show if the fan is operational. Alternately, there are several free utilities such as Mother Board Monitor that can monitor CPU temperature, fan operation and system condition.

Don't be surprised if even after replacing the motherboard, the system still overheats. Using a cooling pad and assuring the vents are clean and clear of obstructions may help.

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)

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.

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.

[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)

If you post the Model Name, and Model Number, I may be able to find a free Service Manual for your Toshiba laptop.

Nvidia 8600gt 512 MB chipset is not working in my DV9700t HP pavallion laptop. Same model is not sold here so HP autorised service centre could not repair it, also this laptop was not having world wide...

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.

B) GPU = Graphics Processing Unit

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.

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.

NOT having worldwide warranty? Oh?

Watch the entire video. Also states a method to fix the problem.

I have a side by side and the fridge part is not cooling enough.

Sounds like a defrost problem. Sears has a complete model number system that is confusing I know. Sears made it that way. Not sure why but look around the cold food door while open and look near bottom on the frame just above the kick plate. The number looks like this, (model No. 253.64802400 for example) Find that number and we can go from there, Thanks, Sea Breeze

Computer part

that looks like a heatsink for your processor.. Did you upgrade the pc at all (hardware wise).. If you look in your computer, on the motherboard, does the CPU(processor) have anything on it?

Also, what is the model # of your motherboard (if you do not know, or can't find it, what is the make/model number of your pc)

Motherboard, cooling unit connection broke

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.
