Ours kept stopping as it overheated - soluion was to get a chap platform to elevate the laptop which allowed it to 'breathe' a bit better and hasn't stopped since. We orginally had it directly on the desk so the air wasn't circulating

Does the ASUS VivoBook S200E-RHI3T73 Notebook have overheating problem


You shouldn't experience overheating issues if you use it properly. Accumulative dirt and dust particles can make any laptop or device heat up beyond its threshold. If you live in a relatively dusty environment, overheating may eventually become an issue for you. You can avoid dust build-up by always keeping it in a protective case when you aren't using it. I'd also recommend (if you don't already know how) learning how to take off a panel and blast it one a year with a can of compressed air.

Keeps restarting itself


Hello,
It could be an overheating issue. Are there any error messages that pop up when it turns off? Try touching the bottom part of the computer, do you feel any heat or something like that?
Try booting to safe mode and observe if it does the same thing inside safe mode. If it does, then you might need to replace the fan or clean the interior part of your computer.

Overheat and shutdown hp mini laptop


Overheating When the CPU overheats then it will shut down (i.e. thermal overload) and won't boot up again until it has cooled down. If this is the problem is not fixed then the CPU will eventually fail.
A faulty fan causes the problem or the fan and heat sink assembly are clogged with 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 sure the vents are clear and dust free. Use a small brush and can of compressed air to do this.

For a week now my laptop has been overheating,then will shut itself down,the overheating happens rapidly,all internet connections have slowed exponentiallyy as a result,is it fan related?the laptop is


The laptop will need to be dismantled down to the motherboard level, use a can of compressed air attach straw and blow out all ports, heatsink and fan. It might be a good idea to remove both for closer inspection and several good blast of air for good measure, and check the thermal paste between the heatsink and processor ic has not dried out.

My dell computer keeps shutting down every 5 min or so. I cleaned th fan and still the problem happens. I bought this almost 4 and a half years ago.


You may have cleaned the fan but have you cleaned the metal cooler (heat sink) under the fan? Its better to remove the fan from the heat sink and hoover it out, then refit the clean fan. Also hoover out the power supply vents too. Also make sure any case vents are clear too. If you think overheating is the problem then run the pc with the case open and if it runs ok then overheating is the problem.

Shuts off in the middle of use for no reason


it sounds like an overheating problem there is a sensor that detect heat to stop from damaging the computer check to see if the fan is running and that its not clogged with dust.also you can try a laptop cooling pad this may help. but make sure the fan in the computer is running and uo to speed you may need a new cooling fan.if it keeps shutting down you may need to have the processor temp checked.with a infared heat sensening gun.

Over heating of laptop


Causes of Laptop Overheating Physical Causes of Laptop Overheating
For a properly designed laptop, the most common cause of overheating is blocked air vents. When dust blocks the fans and air vents designed to cool your laptop, overheating results. (In some cases, blocked vents and poor design are related, as some designs are excessively prone to becoming clogged with dust).
Software Causes of Laptop Overheating
In other cases, laptops overheat because the software designed to protect the laptop – specifically by controlling the operation of cooling fans – does not work properly. In some cases, this is due to problems in the computer’s BIOS, and can be cured by upgrading to the most recent BIOS. In other cases, upgrading or changing the computer’s operating system can cause this software to not function.
If, for example, you have upgraded from Windows ME to Windows XP, the system software designed to operate the fans may no longer work properly. (What’s worse, the laptop manufacturer may refuse to provide support in this instance, on the grounds that you changed the operating system and so are no longer operating the system as it was designed to operate.) In other cases, replacing Windows with Linux has led to this problem if the proper Linux utilities to control laptop cooling were not installed.
Design Causes of Laptop Overheating
In a distressing number of cases, laptop overheating results from poor design by the notebook manufacturers. Some manufacturers cram desktop CPUs into laptop configurations, and do not adequately provide for releasing the heat that these desktop CPUs create. Others simply have failed to provide ventilation and cooling systems appropriate for today’s CPU and video chips, which hold many more transistors than in the past and so generate more heat.
Several class actions have been filed against laptop manufacturers due to overheating laptops, including Toshiba and Dell. Previous class actions have led to settlements under which compensation was awarded to owners of overheating laptops who ran up repair bills trying to get the problem fixed. More class actions related to overheating laptop and notebook computers are reportedly under consideration.check here for more information http://www.fonerbooks.com/lap_fan.htm

Windows(Vista) shuts down without notice


Hi KM,

White scribbles, huh? No text or error codes at all?

It might be an overheating issue. That's a common problem with that system. Try putting a couple of coasters or something underneath it and make sure the battery pack and fan areas can breathe. Also, when it shuts down on its own, is it sitting on a couch or somewhere that breathability might be an issue?

Over heating valiant 671 dp


The power supply and laptop are both hot because your fan isn't working. You'd know if it was working by the whirring sound it would be making. Send it in for service.

If you are trying to say

"I"ve had to replace my battery 3 times in two years, the battery compartment gets very very hot, and the techs couldn't figure out why"

I might be able to help. It's always helpful if you use whole and complete sentences and tell us, with all the specifics possible, what the problem might be.


I TAKE NO RESPONSABILITY IF YOU FRY YOUR COMPUTER OR VOID YOUR WARRANTY. PROCEED WITH FIXES AT YOUR OWN RISK.

You might try a hardware solution to cool your computer, one that won't entail opening it, that will work while your getting or act together to actually find and affect a fix.

Is anyone aware that HP had a battery recall? Apparently the batteries were over-heating and causing problems.

Legal action, Re: over-heating batteries, seems to be in the works here:

You aren't the only person with this problem:

THis is a piece of software you might download, it's called "SpeedFan"

Maybe I can answer your question or give you ideas of other problems that may be causing your problem.

The Compaq 2000 series are known as "bottom breathers" because that's where the fan is. Heat is the enemy of any laptop, of computers, period. For a bottom breather this poses an even greater problem.

I noticed a small componant in a friend's shop. The componant was a small bank of 3 fans, in a laptop size, 1/4 inch plate. The fans blow up underneath the the laptop, to reduce radient heat from the resistance of the current moving through the computer, and to help cool the electrical parts of the computer. The fan under the laptop gets more, and cooler air.

I bought it because the mouse padand the working surface my M2000 get to be about 105 degrees - right at the edge of comfort to the touch.

Since I started using the external fans, I would say that the temperature has come down 10 degrees on the surface of the working surface of the computer and the mousepad.

That might solve your heat problem, which may be causing your battery problem.

I've also been looking into over-heating problems with Compaq models. It seems that several Compaq computer models have over heating problems. These are some fixes that people have tried, with more or less success. Some are very low tech.

=> Add a desk fan to increase over all ambient air circulation.
=> Clean the vent on your computer
=> Suspend laptop over desktop with books on each end, so that there is an air-pace under computer.
=> Build some sort of wood or plastic lift to keep your laptop suspended over your desk and allow airspace and, if you are electronically inclined you can build a fan into the platform.

(Actually, if you build it especially for your computer, you can add seveal fans and vent the unit directly to the laptop fan. Have it plug it into the wall socket and use it at home.

(I bought one from the computer store, premade, 3 fan, but it's generic and doesn't ram air directly into the fan. It just creates dditional airflow to evaporate the heat. It plugs into the USB port on the computer.)

Excess heating problems

1) The heat-sink isn't seated properly, or is loose.
Reseat heatsink, tighten, adding thermal grease and thermal pad(s)

2) Fan is burned out, burning out, or is just not up to par.
Add, or replace existing fan(s) and/or thermal pads on the CPU.

3 ) Use thermal grease between the pad and the CPU and/or fill in gaps between thermal pad,

4) In some Compaqs if the RAM memory chip(s) go bad,
Test by using RAM chips that can be verified as "good" and if need be, install new RAM chips.

4) Sometimes the RAM socket goes bad.
Test them with RAM that can be verified as "Good" and see if your bios and computer notice. Replacing the docking port for RAM might be a job for the shop.

This is a good fix, and I'll probably employ it soon:

tyler said on July 1, 2007 06:58 PM:
My v2000 has been doing the same exact thing. the problem is actually overheating. For some odd reason HP decides to put a thin piece of aluminum foil that seperates the processor from the thermal paste. All I did was remove my HD and battery. then unscrewed every screw and removed the bottom plate. I then took the screws out of the coolant system and removed it to reveal the processorand GPU. at the bottom of the coolant system was a piece of aluminum which I removed. Cleaned out any lint or dust build-up near the CPU/GPU, Then took off the thermal paste from the bottom of the cooling system and spread it evenly directly on the processor heat concentrator. I Put the cooling system back on correctly (must be as tight as you can possibly make it) and screwed the bottom plate back on/ put HD and battery in. Sounds complicated but it really isnt. Also, my CPU temperature is at an all time low of 35-37 degrees (C) browsing the internet. Im not sure if this Voids warranty, but this fix has done wonders and I dont get anymore random shutdowns. I hope this helps some people.

OR this could be the problem if you've recently changed your operating system

Re: Overheating issues with Compaq Presario 2765
Hmm... you recently installed WinXP... did you install the AMD processor driver afterwards? If not, CPU power management isn't enabled. Your notebook still shouldn't crash but if there is a heat problem, enabling power management will help. You'll also need to set your Power Scheme to Portable/Laptop.

1.69GHz (we'll call it 1.7GHz) isn't right, that generation of Turions is 1.6GHz, 1.8GHz, etc. in 200Mhz increments. See what CPU-Z says your speed is, before and after you install the processor driver if that driver isn't installed already. (http://www.cpuid.com/cpuz.php)

I took this next comment from:
http://www.techsupportforum.com/hardware-support/laptop-support/111525-fan-not-running-overheating.html

Check when you first power the computer on whether the fan spins, even if only for a second then cuts out once the Windows logo shows on screen. If so there could be a problem with the windows acpi system. I found that by uninstalling the following :

ACPI Thermal Zone
Microsoft ACPI-Compliant Embedded Controller
Microsoft ACPI-Compliant System

from system devices in device manager then restarting the computer I was able to get the fan operating within windows again. BEWARE before performing this as you will need to reinstall drivers for your modem and video controller after performing this which you probably wont have as compaq doesnt ship the drivers with the notebook and you wont be able to get to the net without modem drivers if you use dial-up.



God I love Google.
