Laptop emachines e725 overheating

Could be simply a blocked CPU vent, clear with a can of compressed air. Make sure Fan is spinning when you power up the PC.

When the fan is spinning place the back of your hand by the Vent you should feel hot air. If you feel cold air the CPU heatsink may need to be reseated with fresh thermal paste. Worst scenario is the Heatsing has Failed and needs replacing.

If the Fan is not spinning it may have failed or a lump of fluff has jammed it

Hp 6720s turns on and then goes off

Ha I like that! "The fun runs for a while and then it stops"

Well we DON'T want that David, lol!

I suggest your laptop is dirty inside. If it has never been cleaned on the inside to your knowledge, it is.

Air is used to cool the hardware components inside the laptop.
The cooling system consists of a;
A) Cooling Tube
B) Heatsink
C) Fan Assembly

The Cooling Tube is a slightly flattened copper tube, sealed on both ends, and filled with Nitrogen.
It has a small flat plate attached to it, that sits on top of the Processor.
There is another small metal plate that sits on the graphics chipset.

[The Processor and graphics chipset are the two hardware components, that give off the most heat in a computer ]

The Heatsink is a thin strip of metal, that has Tall, Thin fins that protrude from it.
In a laptop it is usually rectangular shaped.

The Fan Assembly is a small multi-bladed fan, that is encased in a surrounding cage. (Shroud) Shroud is usually D-shaped.
The flat part of the D is the exhaust opening for the fan.
The fan draws air up in the middle of it, and from the bottom of the laptop.

The metal plates that sit on top of the Processor, and graphics chipset, absorb heat from them.
The Cooling Tube absorbs the heat from the two metal plates, and the Cooling Tube then transfers the heat up to the Heatsink.

The Heatsink absorbs the heat, then radiates it away with it's Tall, Thin fins.
The air flow from the Fan Assembly, helps carry heat away from the fins of the Heatsink.

HP Compaq 6730s which has a similar cooling system,

Scroll down to Step 12 photo.
Here you see a TOP view of the D-shaped fan shroud, and the Heatsink is to the Left.

Scroll down to the last photo on the page.
The rectangular finned Heatsink is to the Right.
You also see the curved copper looking Cooling Tube, and where it states - Heatsink - is the small metal plates.

(That sit on the Processor, and graphics chipset)

A look at a laptop that is dirty inside, using a Dell XPS M1710 for an example,

When the cooling system gets clogged with 'Gunk', the laptop components inside overheat.
[ Gunk = Dirt, dust, hair, carpet deodorizer, lint, food crumbs, name it ]

When a Processor overheats it turns off.
This is a fail safe feature built-in.
Keeps the Processor from burning up. (Sometimes literally!)

Also there is a thermal compound used.
Thermal Paste in-between the Processor, and it's Cooling Tube metal plate;
Thermal Pad in-between the graphics chipset, and it's Cooling Tube metal plate.

[A Thermal Pad is a material that is impregnated with Thermal Paste]

Thermal Paste can dry up over time, and the constant heat inside the laptop. (Thermal Paste in Thermal Pad also dries up)

It then looses it's thermal conductivity properties.

The top of a Processor, and the bottom of it's matching small Cooling Tube metal plate, is not perfectly smooth.
Same with the top of a graphics chipset, and it's Cooling Tube metal plate.

A magnified view would detail, 'Hills, Valleys, and Pitholes'.
Thermal Paste fills these imperfections, and is an Excellent conductor of heat.

Do you wish to disassemble, and clean; and also replace the Thermal Paste, and Thermal Pad?

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,

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,

[ 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,

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 ]

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.

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.

[ Basic example; ]

How to upgrade memory. I need module definition for 1Gig so I can purchase it.

You need a 512MB PC2700 DDR 333MHz SO-DIMM for a laptop (200-pin). The manufacturer I think doesn't specifically support anything over 512MB. But the RAM is standard and I doubt there is any need to buy it directly from Sharp. The laptop only has one upgradable bay so you may not be able to upgrade past 1.25 GB.

One of the memory covers is not removable, if I remember correctly, that is the one under the keyboard. So the one you update is a panel on the bottom.

Sharp PC-AL27

There was a post I read on a notebook forum site that deals with a BIOS problem with the Sharp Actius PCAL27 from a guy named fixyourlaptop AT yahoo DOT com. He stated that he was a Sharp tech, and that the main problem with the AL27 is not the battery, but the BIOS.

There is apparently an issue with these BIOS that causes the power usage of the battery to show incorrectly. I purchased my laptop over three years ago, and just recently updated the BIOS sent me by this fellow, and my laptop battery discharges properly. It still only has about an hour of life but this is the first time it ever worked right.

You can email him for the fix at the above address. Just put in the subject line SHARP LAPTOP AL27 BIOS FIX. He is legit and the fix worked like a charm.

If you want to read his post just do a search for the above (properly formatted) email address on google.
