Well i depends on what motherboard have you got. It must have a setting to tell it on the sensor of the motherboard. Check the BiosSettings

Samsung R519 shuts down unexpectadly


Suspect Samsung R519 is dirty inside.

http://www.cnet.com.au/samsung-r519-339300512.htm

The cooling system for the Samsung R519 is the Cooling Tube, Heatsink, and Fan Assembly.

The Fan Assembly consists of a Fan, and surrounding cage. (Shroud)

The Heatsink is a thin piece of metal, that has Tall, Thin, fins protruding from it.

The fan's blades, center hub, and surrounding cage may become clogged with 'Gunk'
{'Gunk' = Dirt, dust, hair, food crumbs, lint, etc}

The fins of the Heatsink may become clogged. In-between the fins, and all over the fins.

{ The Heatsink absorbs heat. It then radiates the heat way through the Tall, Thin, fins }

When a Processor overheats, (Surpasses it's Thermal Limit), it turns off.
(BIOS turns it off)
This is a fail safe feature built in. Keeps the Processor from burning up.

With the cooling system being clogged, the Processor overheats.

Solution is to clean the laptop THOROUGHLY. I don't believe at this time a can of compressed air for computers, blo-wing air from the outside, will help.

It will just push the 'Gunk' in tighter.

The laptop needs to be disassembled, and thoroughly cleaned out.
It may, or may not need new Thermal Paste for the Processor, and graphics chipset.

(If the laptop has been cleaned recently, and has this problem, it's because the 'tech' probably didn't replace the Thermal Paste.
Thermal Paste will dry up over time, and lose it's thermal conductivity properties )

Do you wish to attempt this cleaning procedure yourself?
If so post back in a Comment, and prepare for a LOT of reading.

(The R520 is VERY similar )

http://forum.notebookreview.com/samsung/117192-samsung-x20-cleaning-cooler-fan.html

The above is for a Samsung X20. Posted, because I would like you to look at the last photo on the page. Here you see an average finned Heatsink, and the 'Gunk' it can collect.

Help my lg 520 restarts while woking on it and the tempreture reaches 70's when in a cool room and it happens more when using battery not direct charging?


I suggest that the laptop is dirty inside.
Air flow inside the laptop is the main cooling source.

A Processor will turn off if it overheats. It's a fail safe feature built into the Processor. (BIOS turns it off)
This is to keep the Processor from burning up.

(A Processor is the 'Brain' of a computer)

The cooling components of the LG 520 (LG A520?), are the Fan Assembly, Cooling Tube, and Heatsink.

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

The tube shaped Cooling Tube has two small metal plates attached to it, at one end.
One plate sits on top of the Processor, and the other plate sits on top of the graphics chipset. (G.P.U.)

Heat is absorbed by the two small metal plates, from the Processor, and graphics chipset.
The heat is then absorbed by the Cooling Tube.

On 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 the heat from the Cooling Tube, then the Tall, thin fins radiate the heat away.

Air flow from the Fan Assembly, (Which is right next to the Heatsink), helps to carry heat away from the fins of the Heatsink.

Point?
There is usually a fibrous type of filter next to the fins of the Heatsink.
This can become clogged with 'Gunk'.

The fins can become clogged with 'Gunk'.
('Gunk' = Dirt/dust/hair/food crumbs/spider webs/etc)

The fan blades, center hub, and surrounding cage, can become clogged with 'Gunk'.

This will lower the cooling capacity of the cooling system tremendously.

Suggest you have the inside of the laptop cleaned out.
You may also wish to use an inexpensive laptop cooler pad, under the laptop.

Toshiba Satellite L500D is shutting down by itself OVERHEATING Clean the fan with compress Air ....> NO GO Need help Please or Any other Suggestion


Disassemble the laptop and remove the heatsink.
Remove all the dried up heatsink goo that's on the heatsink and processor.
Squeeze a small amount of QuickSilver heatsink compound onto the middle of the processor top.
Place the heatsink on the processor and move it in a couple small circles before locking the processor heatsink back in place.
Clean the air vents and cooling fins well while the unit is open.
This should fix any overheating issues you are having (assuming the fan is OK)
If the fan isn't running, replace it.

I have a HP a1630n thee monitor says video cable connected?.The processor fan runs full speed all the time,thats all it does!


The Processor fan usually runs full speed, when the Processor is sensed to be overheating. BIOS, (BIOS program), determines if the Processor is past it's thermal limit. This is done by sensing the Negative value of a Ground to the Processor. If the negative value is too low, BIOS turns the Processor off. [Thermal Limit: A Processor is a type of I.C. Integrated Circuit. http://en.wikipedia.org/wiki/CPU Electrons passing through the miniature circuitry within the Processor, make heat as they move. (One Electron actually hits another Electron. This activates the motion of Electrons, that is soon to become Electricity. Electrons hitting each other create Friction. Friction causes heat) A Processor can only run so hot before it burns up. (Literally in some cases. As in....... On Fire) There is a limit set as to how hot the Processor can still function correctly, and what is the maximum safe limit before the Processor's instructions, starting breaking down. This is the Thermal Limit ] As the heat builds up, the Heatsink, and Processor Fan, cool the Processor down. Helps to keep the Processor, well below it's Thermal Limit. [ The Processor's fan can sit on top of the Heatsink, or it can be a front case fan pushing air through a plastic tuned port, to the Heatsink. Your processor fan is sitting on top of a Heatsink. A typical Heatsink/Fan combo, http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=3451342&CatId=493 Typical construction of a Heatsink, is a flat plate of metal with tall, thin fins protruding from it. Heat is absorbed by the plate of metal, and the fins absorb the heat from the plate, where it is radiated away. Your Processor fan is sitting on top of a Heatsink, which is sitting on the top of the Processor's case] The top of a Processor's case, and the bottom of a Heatsink, are not perfectly smooth. An in-depth view shows 'Hills, Valleys, and Pits'. These form cavities, or voids, that are filled up with Air. Air is an Insulator, not a Conductor. Thermal paste compound is used to fill these voids, and transfer heat from the top of the Processor's case, to the bottom of the Heatsink. Thermal paste is a Conductor. A typical Processor's thermal limit, is usually pretty warm. Time, after time of heating the Processor up, has also heated the thermal paste. Thermal paste can dry out, and harden due to this. It reduces the thermal properties of the thermal compound, to a useless state. It is an Insulator now, and not a Conductor. Doesn't conduct heat. Age also causes the properties of the thermal paste to break down. I would suggest taking a look at the thermal compound. It's always a good procedure to clean the Processor, and the Heatsink, and install fresh, new thermal paste. Decent thermal paste averages around $6, but a 'Mom and Pop' computer shop may have a one Processor application, for around $2.

Switching on but only stays on for a couple of seconds before going blank. If switched off and on it will come on but only stay on for 2/3 second,


Most of the time, owners never clean out the inside of their desktop computer, nor have it done.

Hardware components inside the computer, need a steady supply of air rushing over them, to keep their temperature down. The main hardware component that requires this, is the Processor. If the processor becomes too hot, it is turned off. (BIOS program turns it off)

Without the processor running, there is no computer.

The processor has a Heatsink, and Fan, (Sitting on top of the heatsink), to draw away the heat given off by the processor.
The heatsink is a finned piece of metal, attached to a metal base.

As heat is given off from the processor, it is drawn into the base of the heatsink, and radiated out by the fins.
If the fins become clogged with dust, dirt, hair, and other foreign material, the cooling capacity of the cooling system, drops tremendously.

If the fan blades, center hub, and outside cage of the fan, become clogged with foreign material, the cooling capacity drops termendously.

This in turn, allows the processor to heat up beyond it's thermal operating range, and the processor is turned off. This is a Fail Safe option that is built-in, to keep the processor from burning up.

This is also why it is imperative to keep the heatsink, and fan clean.
Solution for this is to remove power to the computer, (Unplug the computer from surge protector), open the computer case, and use a can of compressed air for computers

There is a Thermal Paste compound in-between the Heatsink, and the Processor. This could have dried up.
The bottom of a Heatsink, and the top pf a Processor have rough surfaces. This cannot be seen readily by the Human eye, but can under magnification.

When the two surfaces, (Heatsink bottom, and Processor top), are mated together, there are Air pockets in-between them, or Voids.
The Thermal Paste fills these voids, and allows better heat transference.
Solution for this is to remove the old thermal compound, and apply fresh thermal compound, (Paste)

The rest of the inside of the computer, needs to be kept clean also. Dust and dirt, are 'magnets' for static electricity. Static will fry out delicate computer hardware components. (Can of compressed air for computers)

Also the Power Supply. The Power Supply has it's own fan to keep it cool, and this fan's blades, center hub, and outside cage, need to be clean. The inside of the Power Supply should be clean also. There are heatsinks inside a personal computer power supply.
(Can of compressed air for computers)

The Dell Dimension 2400 has been around for quite a while, in computer rated time. Came out in 2004.
If this is the original power supply, the power supply could be bad.

Electroytic Capacitors may have gone bad. Rectifier bridge, and also IC's.
Solution is to replace the power supply.

SONY VGNFJ270 LAPTOP BECOMES HOT AND GIVES LOT OF NOISE


If the fan is noisy and the laptop is running hot, then most likely the fan is faulty and spinning slowly. Therefore the fan is not providing sufficent air flow to cool the laptop's CPU. The fan needs to be replaced and possibly the heatsink assembly needs cleaned to remove dust buildup.

Laptop switched off while i was working on it


After the notebook shuts down do not turn it back on for 15 minutes and then test it again. Will the notebook work longer if you let it cool down for a while? Isn’t it hot if you touch the bottom? Can you hear the fan running?
Most likely you experience a laptop overheating problem and it would be fixed by cleaning the cooling module – the heat sink and the fan. The notebook processor produces a lot of heat when the notebook is turned on. The cooling module helps to keep the CPU cool when the laptop is working. The cooling module includes two parts: the heat sink and the cooling fan. The heat sink is attached to the CPU and helps to conduct the heat from the processor to the radiator. The cooling fan blows on the radiator and helps to disperse the heat produced by the CPU. The laptop will overheat if the heat sink radiator is clogged with lint and dust or if the cooling fan stopped spinning.
If your laptop shuts down after some time without any reason and warning, check if the cooling fan spins. Usually it makes some noise and you can hear it. If the fan works fine, then check if the heatsink is clogged. In some cases you can clean the heat sink with compressed air, just blow inside the fan openings on the laptop bottom. If the heatsink is completely clogged, then it is necessary to remove the heatsink for cleaning.
