Some tips:

  • Use a "laptop cooling pad",search on Amazon, you will find many of them
  • Use the laptop on hard surfaces, not a sofa or bed cover, etc.
  • Use compressed air to blow dust out of the fan area (I would do this when the laptop is turned off).
  • Check if the laptop is under warranty and have it serviced. Warranty can be from the manufacturer, the store where you bought it. You credit card may have doubled your warranty.
  • Install the "core temp" program to monitor your laptop's temperature, and alert you when it gets too high. Then you can learn when it is going to shut down.
  • You may be able to run the laptop in a lower power setting, which could reduce the amount of heat generated. This will be under "Power Options" in the Control Panel.

I believe your problem is way beyond,

1) Shooting air in from the outside, with a can of compressed air for computers.
2) Using a Cooling Pad.
3) Adjusting power settings

Either open the laptop up, and properly clean it, or take it to a professional shop.

If you have a basic mechanical aptitude, you can clean it out yourself.

Plus, this is FixYa.com. A Product Support website.
We provide solutions to repair a product. We don't usually refer you to a repair shop, because you already know you can take your product to a repair shop.

1) Work on a table. Do not work on a bed, couch, or directly on a carpeted floor. These are high areas of Static.

2) Suggest you place a Static free soft cloth on the table. Helps prevent scratching the table, and the laptop.
Place the laptop on the soft cloth.

3) Remove ALL power. Remove the AC adapter (Charger) and Battery.

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

Advise buy an ESD wrist strap, and connect the alligator clip to a good ground source.
Basic example of an ESD wrist strap, and shows the average cost,

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

(It isn't just a piece of wire connected to your wrist, via a piece of metal against your wrist. In the wrist strap there is also a 1 MegaOhm resistor)

I connect to an unpainted surface, of the metal frame of an open, empty desktop computer case.
Not everyone has one of these laying around.

{I do not use an Anti-Static Mat, and will state why when asked)

If the table you are working on has metal legs, connect to an unpainted surface of one of them.
Barring this is not feasible, perhaps place a large metallic object on the table, and connect to it.
A large metal serving tray, or large metallic knickknack. (Unpainted)

Fan/heatsink assembly

The Cooling System consists of a Cooling Tube, Heatsink, and Fan Assembly.

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

Towards one end there are two metal plates. One towards the end of the Cooling Tube, and one further up.

The one at the end is larger, and sits on top of the Processor.
(Has 4 screws holding it down)
The other metal plate further up is smaller, and sits on top of the graphics chipset.

At the opposite end of the Cooling Tube is the Heatsink.
This is a thin piece of metal that has Tall, Thin, fins protruding from it.
The Tall, Thin, fins radiate the heat away. Just like the principle used for a house radiator, or automotive radiator.

Next to the Heatsink is the Fan Assembly.

This is shown in Step 20 of this pictorial disassembly guide,

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

(You can see the black Fan's blades, and the silver/black shroud around them. The black finned Heatsink is above the Fan Assembly, and is hard to see because of the white InsideMyLaptop logo )

(The Processor, and the graphics chipset, are the two hardware components that give off the most heat.

When a Processor overheats, or passes it's Thermal Limit, it turns off.
BIOS turns it off. This is a fail safe feature designed to keep the Processor from burning up)

Heat is absorbed from the top of the Processor, and top of the graphics chipset, by their two metal plates.
It is then absorbed by the Cooling Tube.

The Cooling Tube transfers the heat TO the Heatsink.
The Heatsink absorbs the heat, then radiates it away with the Tall, Thin, fins.
Air flow from the Fan Assembly helps to carry heat away from the fins.

The blades, center hub, and surrounding cage (Shroud) of the Fan Assembly, can become clogged with 'Gunk'.
So does the fins of the Heatsink, and opening for the Fan Assembly at the bottom of the laptop.

{'Gunk' = Dirt, dust, hair, food crumbs, lint, etc}

When the cooling system becomes clogged, the cooling capacity drops tremendously.

Air from a can of compressed air from the outside, will just push the 'Gunk' even deeper into the cooling system. The 'Gunk' needs to be physically removed.

Method is to take Q-tips, and a soft small brush, (Makeup brush?), and disturb the outer 'crust' of the Gunk.
(Crude explanation; Stir the Gunk around a little, then it is easier for the air to remove)
Then compressed air is used to remove the Gunk.

There is one more issue that should be brought to light.
Thermal Paste.

Thermal Paste is used in-between the Top of the Processor, and Top of the graphics chipset, and the two metal plates that sit on them, that are on the Cooling Tube.

{The top of a Processor, and the top of a graphics chipset, are not perfectly smooth.
Neither is the bottom of the two Cooling Tube metal plates.

A magnified view would show, 'Pits, Valleys, and Hills'.
These imperfections create air pockets.
Air is an Insulator, not a Conductor.

Thermal Paste fills these imperfections, and is an Excellent conductor of heat)

After time, and with constant overheating, the Thermal Paste dries up.
It loses it's thermal conductivity.

Due to the LOW cost of Thermal Paste, and the fact you are this close, it is prudent to replace the Thermal Paste.
(It's cheap insurance)

In the photo in Step 20, you see the 4 Philips head screws that hold the cooling system in place. These are circled in Red.

Loosen the screws all the way. The PREFERRED method is to loosen one screw, then go to the opposite corner, and loosen that screw.
Keep going back, and forth until all 4 are loosened.

Then you can lift the cooling system off, as shown in Step 21.

Here you will see a pasty substance on top of the Processor, and graphics chipset. (The Processor is the one under the metal plate with 4 screws)

Use a plastic scraping type object, to remove as much thermal paste as you can. (Non-Static)
I use an old plastic credit card. (GOOD use for a credit card!)

{A Processor is the MOST susceptible hardware component to Static shock}

Scrape off some thermal paste, wipe the scraper off with a static free cloth.
Keep going, and remove as much thermal paste as you can.

Follow with Q-tips dipped in Isopropyl Alcohol. (91 percent is best, but 70 percent will do. Rubbing Alcohol)
It's a gooey mess sometimes, and may take a few (10?) Q-tips dipped in alcohol.

{CAUTION!!
Isopropyl Alcohol is EXTREMELY FLAMMABLE.
Use in a Well ventilated area with NO sparks or flames present! }

When the Top of the Processor, Top of the graphics chipset, and bottom of the two Cooling Tube metal plates, are clean, you could literally eat off them.
Yep, THAT clean.

After the areas are clean, apply ONE small pea sized drop of Thermal Paste, to the MIDDLE of the top of the Processor, and the top/middle of the graphics chipset.

Carefully set the cooling system back in place, with the screws lining up to the holes in the motherboard.

TIGHTENING:
Ease down one screw until it just touches. Go to the screw in the opposite corner, and do the same. Now do the same for the other two screws.
You are tightening down EVENLY.

Slightly tighten the first screw, then the screw in the opposite corner.
Go to the screw on the same side, and tighten it. Now to the screw in it's opposite corner.

The metal plates of the Cooling Tube MUST sit flat, on the top of the Processor, and top of the graphics chipset.

Warning!
IF, you use Artic Silver 5 thermal paste, or a similar paste that has real Silver in it.

As stated it has real Silver in it. Silver is an excellent conductor of heat.
It is ALSO an excellent conductor of electricity.

IF you apply too much, when the Processor heats up to operating temperature, the thermal paste will ooze off.

It can then ooze down to unprotected solder joints, and the contact pins of the Processor. (And solder connections of the graphics chipset)

This will create a Short Circuit.
PROPERLY apply thermal paste,

http://www.hardwaresecrets.com/article/274

Example of thermal paste,

http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=3829122&CatId=503

If you need guidance simply post in a Comment.

IF, you feel this is beyond your capabilities, and take it to a professional computer repair shop, I advise tell them you want the thermal paste replaced, for your $50 or $100 you are going to pay them.

Not air from the outside, or partially remove the top of the laptop, and b-low it out.

You want the Heatsink, Fan Assembly, and inside of the laptop cleaned out, and the thermal paste replaced.
Fan Assembly may need to be replaced also.

    To Add:
    It may not be Thermal Paste that is used. There may be a Thermal Pad.
    A type of cloth that is impregnated with Thermal Paste.

    These are junk, and cannot be reused anyway.
    Remove it, throw it way. Use thermal paste after you have cleaned.

  • David Nedde Feb 12, 2012

    That is a very thorough solution.

    However, I suspect this laptop may have an inherent design flaw that causes the overheating, given the number of complaints about this model, so I'm not sure any amount of cleaning will solve the problem. It is worth a shot, although it can be time consuming.

  • joecoolvette
    joecoolvette Feb 13, 2012

    My guess is the owner has never had the laptop thoroughly cleaned, David.
    But, the overheating issue for this series, can be overcome as in this video example, http://www.youtube.com/watch?v=JEpnqhRYG...

I have a problem with my compaq presario cq60 due to overheating atimes the laptop turns off automatically when it gets too hot with is the problem


check the underneath of the laptop, there should be several access panels, remove these and look for fans, clear them of any dust you can see, the main fan should be blowing through a heatsink (lots of small fins) try to get to the part between the fan and heatsink as sometimes you can get a lot of dust build up there.

How to Prevent Laptop Overheating


There are some laptops that get hotter than other laptops. Laptops get hot due to many factors such as capacity of the processor, cooling fans,ventilation, extra items such as modem, video cards. They all produce heat due to which laptop gets hot.

You'll find many examples on the Internet for the laptops which get hot. There are particular laptop models which produce excessive heat. For example, IMB T60,Apple Mac Book Aeros, Compaq 610, Dell D400 etc.

But you don't need to worry now because there are certain methods by which you can stop overheating of your laptop. These methods are discussed below.

Place your laptop on a cool flat surface while working. It will allow the air to enter your laptop. Some laptops have cooling fan underneath and blocking this will make your laptop hot quickly.

Buy a laptop stand from a laptop seller. It lifts your laptop few inches from surface of the table making a reasonable space for air to enter your laptop freely.

Dust your laptop regularly; it will keep your laptop's fan functioning properly for a long period. The fan needs to do an extra work when there is dust inside the laptop. If you dust regularly, the fan will not experience any difficulty.

Shut down your laptop before putting it in the bag. The atmosphere inside the bag may be too hot for your laptop, and it can damage your laptop.

When the battery is full, unplug the charger. People make a common mistake leaving the laptop plugged in. Due to the constant supply of electricity to the laptop will heat its battery as a result it will overheat your laptop.

You can find certain kinds of items in many electronic stores for keeping your laptop cool. Cooling pad is a most common equipment to keep your laptop cool that sits beneath your laptop and is powered on with the help of USB port. It increases the airflow inside the laptop. So, cooling pad is the best you can take to keep your laptop cool and maximize its performance.

Give your laptop a little break if it is getting hot. It can shut down itself to protect any kind of damage due to overheating. This is an indication that your laptop needs a little break.

Do not expose your laptop to the sunlight for a long span of time.

Screen turns off but computer stays on. Also the area were the cooling fan gets extremely hot.


It could be overheating. The screen turn-off is possibly a failsafe mechanic to keep the circuitry from developing a fault from the high heat.

Try leaving it to cool for a while, maybe an hour or two, then turning it on. When the screen turns off try holding down the power button, then turn the laptop back on. If the screen turns back off after a much shorter time than from when it was cool, it's probably overheating which could be from a build-up of dust in the fans, meaning you'd need to get it over to a repair centre to fix it.


However, it could also be a software issue. It's worth running a virus scan using AVG or avast, both of which are free. It's always possible malware is causing your issues, though it sounds like a hardware problem to me.

Hi,

Check your CPU fan, it may be clogged with dust/lint. Many times laptops do that due to overheating. Get a blower or Dust Remover (compressed Air) to clean that out

I found a trojan and a couple of virsues on my compaq 60 laptop. everytime i tried to scan my laptop it would overheat and shut down. I have taken it into a shop and they said theres nothing they can do...


Hello,

I propose two solutions :-
1) Just format your machine once and install the OS again. Observe if it is behaving same.
2) If yes then you need to replace your Cooling FAN.

Abrupt shutdowns


Is it very hot?

If so Tkae compressed air and blow it into all the vents on the computer. You are trying to loosen dust. Get it all loose possible near the vents then **** out all dust you cna with a vacuum cleaner.

This should stop the laptop from overheating and shutting down.

Keeps Shutting Down


First, start by taking the fan and heat sink out and cleaning them. Dust build up can cause overheating. Also check the fan for hairs or carpet fibers that have gotten wound in it, I've had fans stop working due to this. Then put it back together and check to see if the fan is coming on and running in regular intervals. If it's not it will need replaced. If it is, then there may be a malfunction with the processor or a short on the motherboard.

Compaq presario v2000 overheating issues...


Yes, this is a fairly common problem with the v200o, caused by a lack of good fan airflow. Your best bet in using it would be to get a laptop pad. This will not only keep your laptop cooler, it will prevent your legs from blocking the fans when it is on your lap.

Good luck!
