Question about Sony VAIO FRV25 Notebook

1 Answer

Startup issues I recently ordered a new processor cooling assembly in order to replace the two fans. Instead of messing with the processor i simply swapped out the new fans with the old ones and then reinstalled the cooling assembly to the mother board. Now that i have everything back together the way it came apart i am trying to start up the computer, and it will not start up. It did get as far as the HD spinning and it acted as though it was working for about 10 to 20 seconds and then it shut off. Now it will not get any farther than the green light lighting up and then it shuts off. Any ideas? Has anyone ever reinstalled the processor/cooling assebly - what does that process look like...did i miss something? Thanks!

You need to Apply Thermal Paste to the top of the processor Chip..then place the heatsink/Fan assembly on top.. then screw the 4 screws down 3 turns at a time going from screw 1 to screw 2 to 3 then 4 and do again 3 turns.. repeat till all are tight..
The amount you use is: A thin layer.. (thickness of a dime)

My acer 5750g notebook is bocomming hot and noisy on the power source side


The cooling fan will need to be replaced, go to www.ebay.com Type make and model of laptop, refine search to cooling fan. In order to fix this properly the computer must be dismantled down to the motherboard level, remove old fan and heatsink and blow out dirt and dust with a can of compressed air, next remove old thermal grease with rubbing alcohol and a paper towel from the processor and heatsink, now apply fresh compound and assemble along with the new cooling fan.

well for starters you can use a small vacuum to bring that dust out of the pc. Opening the notebook to evacuate the fans will take some serious time and patience try the vacuum first then report back

My dell inspiron laptop produces howling


I believe the problem may be the cooling fan, of the Fan Assembly.

Dirt, dust, hair, food crumbs, lint, you name it, can be drawn up into the laptop by this fan.
This can cause a strain on the fan's bearings.

It could also be that the fan's bearings have simply failed. They are dry, hence the occasional howling noise.

The method is to open the laptop, and physically check the fan.

Dell Support > Inspiron 5100 Notebook PC > Service Manual,

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

FIRST thing;
FOLLOW Anti-Static Precautions.

Anti-Static Precautions:
Your body carries Static electricity. Static WILL fry out (Short Circuit), the delicate hardware components inside a computer.

Suggest wear an ESD wrist strap, and connect it's alligator clip to a good ground source. (Electro Static Discharge)

Basic example of an ESD wrist strap,

http://www.radioshack.com/product/index.jsp?productId=2103245

[ I connect to an unpainted surface, of the metal frame of an open, empty desktop computer case. Just one example ]

On the Dell Support > Service Manual page, click on -
Microprocessor Thermal-Cooling Assembly

This shows the Fan Assembly. It is connected to the Microprocessor Thermal-Cooling Assembly.

Another view of the Fan Assembly,

View of the Microprocessor Thermal-Cooling Assembly, with the Fan Assembly,

http://www.laptopbattery-usa.com/dell-inspiron-1100-5100-5150-laptop-cpu-cooling-fan-p-1238.html?zenid=okh2t54jgsg369stoj7gipf3k5

See the 4 screws sticking up, and the squarish metal plate they go down in?
This plate sits on top of the Processor.

The two curved slightly flattened copper pipes, are Cooling Tubes.
They are sealed on both ends, and are filled with Nitrogen.

They attach to the squarish metal plate, that sits on top of the Processor, and the other end of them goes to a Heatsink.

This cannot be seen in the photo.
The Heatsink is a rectangular finned object.
Has Tall, Thin, fins.

Heat is absorbed from the Processor, by the squarish metal plate sitting on top of it.The Cooling Tubes then absorb the heat from the squarish metal plate.

Heat is then transferred along the Cooling Tubes, to the Heatsink.
The Heatsink absorbs the heat, then radiates it away with it's fins.
Air from the Fan Assembly, helps carry heat away from the Heatsink fins.

The Fan's blades, center hub, and surrounding cage, (Shroud), must be clean. If the fan's blades are dirty, the result could be an unbalanced fan.

Makes the fan tilt to one side, and possibly scrape the blades on the Shroud.
Also over time the dirt, dust, etc, can cause the Fan's bearings to fail.

Gently see if you can move the Fan up, and down. Gently grab a blade of the Fan, and see if you can move the Fan. You will know if the Fan's blades have too much movement up, and down. (Or tilt to the side)

If the Fan is bad, (Bearings), see if you can buy just the Fan, and replace it.
If not you may wish to replace the entire Microprocessor Thermal-Cooling Assembly.

Should this be the case post back in a Comment.
I need to guide you in proper replacement.

[ You need to Thoroughly clean the top of the Processor, and the bottom of the squarish metal plate that sits on it.
Then Thermal Paste needs to be Properly applied, and the 4 screws tightened down in a sequence ]

I have a dell Costco 1500 that wouldn't come on. I changed the battery but after a few Dave it quit working again. I messed with the ac adapter & got it going but it gets really hot.


If the laptop is running to hot, the problem is in the cooling fan and blocked heatsink ports. The computer must be dismantled to access the motherboard, remove fan and heatsink, use a can of compressed air and clear out all the ports and fan, next get rubbing alcohol and paper towel, remove thermal grease from the processor and heatsink, now apply a fresh thin layer to the processor and heatsink and assemble, this will cure most heat related issues.

Compac cq50 110us has always run hot but now it overheats corre temp gadget reads temp at 205f then commences shut down vents are clear and a tech ie brother in law opened and cleaned system of all debris ...


I find that when completely cleaning a laptop, I will remove the Heatsink/Cooling Tube combo.
Allows me to thoroughly clean in-between the fins, and around the fins, of the Heatsink.

Also allows me to THOROUGHLY clean, the bottom of the cooling tube's metal plates, that sit on the top of the Processor, and GPU.
(GPU = Graphics Processing Unit. Slang? Graphics chipset )

Also the top of the Processor, and top of the GPU.
Then fresh, new Thermal Paste is Properly applied, and the Heatsink/Cooling Tube combo reinstalled.

Thermal Paste dries up over time. When it does it looses it's thermal conductivity properties.
Due to the cost, and ease of replacing, it is just cheap insurance.

There may not be Thermal Paste used. Computer manufacturers also use a Thermal Pad.
A material soaked with Thermal Paste.

CANNOT be reused. Once the metal plate/s of the Cooling Tube squeeze down on the thermal pad, there is an imprint made.
Trying to reinstall the Cooling Tube, will not squeeze the thermal pad down any further than it was originally.
The same amount of pressure is used. A gap will result. In-between the surface of the thermal pad, and the metal plate of the Cooling Tube.
{Thermal Pad's are J-U-N-K. They loose their conductivity properties pretty quickly}

1) You were having a cooling problem in the beginning, and this IS one definite area to address, along with cleaning.

2) You are right there with full access, when thoroughly cleaning a laptop.
Access to the cooling system.

A) Did your tech i.e. brother-in-law address this issue?

B) If so what thermal paste was used, and what was the method of applying?
(Method of applying?
Yes. It matters. Especially if a compound like Artic Silver, or similar to, was used)

C) Cooling fan is rotating? Good. Now, what RPM is it spinning at?
Spinning too slow will cause overheating problems also.

Are you sure the Cooling Fan is not spinning intermittently?
Spins okay for a while, then slows down, or stops, then spins again.

D) Let's look at the Cooling Assembly, for the Compaq Presario CQ50 series of Notebook PC's,

Top View, palm rest (Top Cover Assembly ) removed,

http://www.insidemylaptop.com/remove-motherboard-from-compaq-presario-cq50-cq60-cq70-laptop/

Scroll down to Step 17.
To the upper left of the photo you will see the black Fan Assembly. (Most of)

{ Fan is inside a surrounding cage, or shroud. You can see some of the Fan's blades. The Fan and the Shroud, are the Fan Assembly}

Just disassembling down to this point, in order to clean, is Not enough.
You cannot thoroughly access the entire Heatsink. The motherboard must be removed in order to perform this.

You also cannot clean, and replace Thermal Paste.

Observe Steps 18 and 19.
Shows the motherboard being removed, and removed.
Same direction. Top facing up.

Observe Step 20
This shows the Bottom side of the Fan Assembly, and also shows the rest of the cooling system.

Fan Assembly to the top right. Coming down the right side of the Fan Assembly, and curving under, is the copper Cooling Tube. (The Cooling tube is a slightly flattened copper tube, sealed on both ends. It is filled with Nitrogen )

Coming along the Cooling Tube area under the Fan Assembly, is an aluminum small rectangular plate. This metal plate sits on the GPU,

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

Going further to the left, is the metal plate that sits on top of the Processor.
You see the four mounting screws for this metal plate, circled in red.

Step 21 shows the cooling assembly removed.
{The Cooling Fan Assembly, and the Heatsink/Cooling Tube Assembly, are two different assembly's.
Referring to both as the Cooling Fan Assembly, as in the article, is erroneous }

3) Heat from the top of the Processor, and graphics chipset (GPU) is absorbed through the Thermal Paste, and into the individual metal plate sitting on top of it.

The plates transfer the heat to the copper Cooling Tube. The heat is then transferred to the Heatsink, at the end of the Cooling Tube.

Air from the Fan Assembly goes through the fins, (And around the fins), of the Heatsink, and helps to carry heat away.

4) Thermal Paste
The top of a Processor, the top of a GPU, and the bottom surface of the metal plates which sit on them, is not perfectly smooth.

A magnified view would detail, 'Hills, Pitholes, and Valleys'.
When the two surfaces are mated together (Metal plate to Processor, metal plate to GPU), air pockets are created.

Created in-between the two surfaces.
Air is an Insulator. Not a Conductor.
Thermal Paste is an Excellent conductor of heat, and fills those imperfections. (Air pockets)

Tip:
When I state Thoroughly clean, for the top of the Processor, top of the GPU, and bottom of their matching metal plates, I mean THOROUGHLY.

For additional questions please post in a Comment.

Toshiba laptop fan speed up and then slow down issue. Feedback


I have a toshiba and that is exactly what the fan is doing to cool off the processor. That is because when you boot XP the fan stops after 30 seconds is simply it has no difficult operation on it. But when you choose to switch on to Ubuntu your fan doesn't stop is because ubuntu requires more air since it has so much effort on its operation. Mind you when you installed ubuntu, it requires larger video graphics memory than the XP OS. Try to execute more websites on different tabs on your XP and you will find your fan will work overtime because you put much required operation for the processor. But to help the fan cools off the internal devices, place cooling pad beneath the notebook so that your PC will be safe.

Thanks...

The HP Presario A900 shuts down within 5 minutes of start up


If your laptop is overheating, it means that the Processor fan is not working. You can damage it further if you keep trying to us it. Although I must say, this is the first time I've heard of using frozen veggies to cool it down. I have a client that bought a portable Air conditioner to cool his laptop. I fixed it by replacing the fan.

The fact that the unit works while being cooled externally points directly to the fan.
Is the unit out of warranty?
If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.
Thanks, Joe

Overheating


Overheating is a big issue with Gateway. It mostly involves problems with the fan. When Gateway receives a warranty fan problem they replace it with a fan that is reconditioned or rebuilt (probably from another cutomer's unit like yours) and they don't seem to last long. To make sure it is a fan problem, which is the most common, Turn on the laptop and wait to see if the fan is turning on. It won't take long, processors get hot quick. The fan should turn on and run anywhere from 3 to 15 seconds then turn off. It should do this approx every 5 to 7 minutes in order to keep the processor cool. If it doesn't work at all, works seeming sporadically, or the processor gets really hot before the fan starts, then it's a fan problem, and a NEW fan should be purchased. If the fan works properly, then it could be that the fan and heat sink need to be cleaned internally due to dust build up.
