Question about Acer Aspire 5520-5579 Notebook

3 Answers

Acer aspire 5520 won't power on.

I had some heat issues in the past. i opened up my acer and found a lot of dust accumulated in the cooling fins. i cleaned it off and when i powered it on it ran better than in months. it ran fine for a few days. when i was plugging in my eternal hard drive (USB powere by the same US cable) the lap top crasehd instantly at the time of USB connection.
now when i try to power it on, the green power led goes on. the fan does turn on but will not go into its full rpm momentarily as i think it should. the screen never goes on and after about three seconds the lap top shuts off again and this cycle is repeated endlessly. the bios are never reached. i am not sure if the machine actually turns on or if the power led just signals an error state of 3 seconds on, 1 second off. the ram led does the same and the wireless led goes on momentarily for each cycle.
any idea what this could be?

    my laptop apparently had a bad mother board and media card. i got both replaced by warranty, which took care of it...
    now that the thing works i take apart about once a month to clean out dust from the cooling fins to maximize cooling effect and prevent it from slowing down...makes all the difference in the world...

My computer suddenly shut down without notice. It does it when I'm using battery power and it will also do it if the battery is out of the laptop and I'm using the power cord..

Suggest laptop is dirty inside.

Air is used to cool the hardware components inside the laptop.
If 'Gunk' coats these cooling components, (finned Heatsink, and small Fan Assembly), the cooling capacity of those cooling components drops Tremendously.

['Gunk' = Dust, dirt, lint, hair, food crumbs, name it ]

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

Using Dell XPS laptop to show you the 'Gunk' that can accumulate,

This is an example of part of the cooling assembly; for an Acer Aspire 7720 series of Notebook PC,

Click on the photo to enlarge.

The curved copper tube is the Cooling Tube.
Slightly flattened copper tube, sealed on both ends, and filled with Nitrogen.

At the top of the view, on the Cooling Tube; is the small metal aluminum plate that sits on the Processor.
4 Philips head mounting screws.

At the bottom in the view, is the rectangular finned Heatsink.
The last cooling assembly part is the Fan Assembly,

The small fan is a multi-bladed unit, that sits in a D-shaped shroud.
In the view the Bottom is the opening.
The opening sits RIGHT AGAINST the finned rectangular Heatsink.

Heat is absorbed by the two small metal plates on the Cooling Tube, from the Processor, and GPU.
The heat is then absorbed by the Cooling Tube, and transferred to the Heatsink.

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

If the Fan Assembly's fan blades are coated; and the fins of the Heatsink are clogged; the cooling capacity drops TREMENDOUSLY.

Your Aspire 7720 may also has a separate Cooling Tube, and Heatsink; for the graphics chipset. G.P.U.,


The top of a Processor, and the top of the graphics chipset; is Not perfectly smooth.
Neither is the bottom of the metal plates of the Cooling Tube/s, that sit on them.

A magnified view would detail, 'Hills, Valleys, and Pitholes', in the surface.
When the two parts are mated together, (Processor/Cooling Tube plate; Graphics chipset/Cooling Tube plate); there are air pockets that are created.
Created from the imperfections listed above.

Air is an Insulator; not a Conductor.
Thermal Paste fills these imperfections, and is an Excellent conductor of Heat.

There may be also Thermal Pads that are used. Pad material impregnated with Thermal Paste.

After time, and repeated heating from the Processor, and GPU, (Graphics chipset), the Thermal Paste dries up.
It also looses it's thermal conductivity properties.

SINCE, all you have to do is remove the large panel, from the bottom of the laptop, (Battery Compartment facing Away from you; the large panel to the Right), you have full access to all cooling components.

It would be in your best interest to remove the Cooling Tube/s/Fan Assembly, and clean the top of the Processor, and GPU. Also the metal plates of the Cooling Tube/s.

I use an old credit card to scrape as much of the old Thermal Paste off, as I can. (Needs to be plastic, or wood; because it needs to be Anti-Static. NO -> Metal scraper)

Use Q-tips dipped in Isopropyl Alcohol. (Rubbing alcohol)
91 percent is best IMHO, but 70 percent will do.
To me 50 percent = No. 50 percent Water, and 50 percent Alcohol.
Takes a LOT of alcohol soaked Q-tips, as it's usually a gooey mess.

Isopropyl Alcohol is EXTREMELY FLAMMABLE!
Use in a WELL ventilated area with NO sparks or flames present!

How clean? Literally clean enough to eat off of. (Don't worry about excess alcohol dripping down. It will evaporate)

Now PROPERLY apply fresh, new Thermal Paste for the Processor, and CUT a new Thermal Pad for the GPU.

{Old thermal pad is carefully peeled off }

Screws for the Cooling Tube processor plate, and GPU Cooling Tube plate; are lightly tightened down until they touch, then tightened in a crisscross fashion.

You want the plates to sit F-L-A-T on the Processor, and GPU.

Free Service Manual so you can disassemble,

Go to the 'paragraph' that starts with Aspire 1200. (1200 in Blue)
Drop down to the 12th line. (7530G in Blue)
Scroll across, and click on 7720 in blue.

This is a PDF file. The computer you are using now has Adobe Reader on it, which uses PDF files.
After you click on the file name (7720) it may take up to 30 seconds, before the first page comes up.
(The PDF file is downloading in the background)

Buy and use an ESD wrist strap. Connect it's alligator clip to a good ground source.
Electro Static Discharge.

Your body carries Static electricity. Static WILL fry out (Short Circuit), the delicate hardware components inside a computer.
You CANNOT just touch the metal framework, as you would for a desktop computer; to relieve your body of Static.

Average price is around $3 to $6. Here is but one example,

I connect to an unpainted surface, of the metal frame of an open, empty desktop computer case.
I feel an Anti-Static Mat is unwarranted. (And I have a repair shop)

You can set a large metal serving tray (Unpainted), on the table you're working on; and connect to it.
Or a large metal knickknack. (Unpainted)
You get the idea.

Use a mutli-compartment container for the various screws you will remove. Label each compartment for the area the screw/s come out of.
SOME screws look VERY similar to other screws.
Advise DO NOT mix them up!

Use a small soft bristle brush, (Makeup brush?), Q-tips, and a can of compressed air for computers, to clean the inside of the laptop out.
Especially the fins of the Heatsinks, and Fan Assembly.

Acer ASPIRE 5732Z overheats and then shuts down what can I do?

Find out what is causing it to overheat. You'll have to take the laptop apart to fix the problem.

Three causes of overheatting.

1) Dust - Dust inside the laptop. Dust clogging the fans and vents. Dust around the cpu and heatsink. Take a can of compressed air and blow out the dust.

2). A fan not working. Replace the fan.

3). The Thermal Paste around the CPU and Heatsink has dried up or is too thin to keep the unit cool. Put on a fresh coat of Thermal Paste.

You could just purchase a Laptop Cooling Pad that has 3 fans on it, and plugs into the usb port of the laptop and the laptop sits on it to keep cool. They are less than $20 at Tiger Direct. When the site comes up just type: Laptop Cooling Pad in the white search box at the top of the webpage then click GO. Sort the returned results by Price Low to High.

Below is a link to one I use for repairs when I get a hot laptop for $12.99

Acer Aspire 4930 heats up very quickly

When the CPU overheats then it will shut down (i.e. thermaloverload) and won't boot up again until it has cooled down. If this is theproblem is not fixed then the CPU will eventually fail.
A faulty fan causes the problem or the fan and heat sink assembly are cloggedwith dust.
Check the CPU fan to see if it spins freely, if not replace the fan.
If the fan and heat sink is clogged with dust the remove the dust and make surethe vents are clear and dust free. Use a small brush and can of compressed airto do this.

Why does the fan sound as if it's hitting on something?

Its has accumulated a lot of dust and the dust is causing it not to spin correctly and therefore making a clapping noise , use a powerful hoover and **** the dust out of the fan

its either dirt or one of the fins on the fan has broke or the bearing inside is broken

My acer aspire 5315 shuts off suddenly and won't restart till it wants to. I replaced the battery, no difference....what's wrong?

This could be a sign that your laptop is overheating. If you touch the laptop while it is running & you find it too hot, make sure that the fan is running properly & that the air ways are not blocked.
You can blow compressed air into the cooling vents of the fan. If you notice clouds of dust coming out, then it might be a good idea to disassemble the laptop, clean the fan & air ways, & reassemble it back. If the fan has failed & is no longer running, it might need to be replaced

I have a ACER 5735 . The laptop shuts down suddenly while its on and sometimes im not able to switch on the laptop and even if i switch on , then once again the power goes off immediately . What would be...


The reason for the sudden shut down of your computer is because of overheating of the 'case', where the CPU is mounted. Overheating can be due to dust accumulation on the heat sink, which prevents dissipation of heat. The possible solution to combat overheating issue is to keep the laptop dust free by cleaning out debris at the vents frequently. Note that a laptop has a much smaller cooling area in comparison with desktops and hence laptops tend to accumulate dust a lot quicker than desktops. This is because all the dust/debris, in the case of laptops, accumulate in the cooling fins.

My acer aspire 3000, keeps turning off when i have it pluged into the wall. why is it doing that and can anyone help me...

Computer shutting off after a few seconds to a few minutes

This sounds like an auto shut-off signal given by the processor because of a possible over-heating issue. This usually happens when the laptop has been run for an extended time without having the dust, dirt and debris cleaned from its cooling vents and grills. After time, the thermal paste on the processor bakes under the extreme heat and starts to flake off and lose its efficiency at cooling the processor.
Get a few cans of compressed air that you would buy at an office supply store and using short bursts, blow out the dust and dirt from all the ventilation grills and vents first, make sure the laptop is powered down and battery removed. Then, open all the compartments and clean them out as well including the cd/dvd tray. There is a small black hole on the dvd bezel, just stick an open paperclip in it and it will pop the tray open. Blow a good blast in there to clean the dvd player.
There is the possibility that the thermal paste will have to be replaced, that means you need to gain access to the heatsink and remove from the processor, clean all the old thermal paste from it and apply a small thin layer of new paste to the top of the processor and replace the heatsink, securing it evenly with the attached screws.

Acer Laptop runs but shuts off suddenly

this is an overheating problem, computer have a thermal protection sensor that senses extreme temp.
i suggest return to your service provider and have them check again, it could probably cause by, the fan isnt plug or there is a lot ob obstruction to exhaust that tned to build up heat around your pc

Acer 5520 power shutdown

Possible heat issue. Check the cooling fans and see if theyre running. Usually one on the bottom, back or side of the laptop. Make sure that the cooling vents arent blocked during use.
