The cooling fan in your laptop helps to keep your CPU (Central Processing Unit), or processor from overheating. Your cooling fan will collect a lot of dust and debris which can possible cause a short in the cooling fan. Routine fan cleaning is essential to the life of your laptop. If your CPU overheats it can go bad and/or cause damage to other important components inside your laptop. The hardest part about cleaning a cooling fan is gaining access. This requires some disassembly of your laptop.

Turn off your Dell laptop, disconnect the power cable, remove the battery pack and disconnect any other cables or external devices. Attach an Antistatic wrist wrap to your wrist and attach the wire clip to the laptop frame. This will help prevent against shock from static electricity. Use a small flathead screwdriver to pry up on the keyboard bezel. The keyboard bezel is a small plastic strip located between the laptop's keyboard and LCD display. Remove it completely from the laptop, and set it to the side. Remove the now-exposed two to four Phillips-head screws (depending on the laptop model), and then lift up on the keyboard and place it face-down over the track pad and palm rest. Disconnect the keyboard's ribbon connector from the laptop's motherboard. Lift the keyboard out of the laptop base and set it to the side. This will expose the Dell laptop's cooling fan. Remove the single Phillips-head screw attaching the fan to the motherboard. Lift the fan out of the laptop base; you're now ready to clean.

A bad capacitor can cause a variety of computer problems, but if you can identify the faulty capacitor you may be able to replace it and save your computer.

Capacitor
Capacitors, sometimes also called condensers, are used to store energy in an electric field. In the context of computing, capacitors are used to block the direct current being circulated around the motherboard. A typical capacitor should last up to 15 years, but some computer manufacturers use substandard capacitors resulting in shorter lifetimes. Computer Problems b> When a capacitor has gone bad on a computer you may experience a large range of problems. The computer may have trouble booting up, or it may shut down without notice after running for only a short period of time. The most common problems associated with faulty capacitors are that they cause unexpected computer crashes and general reliability issues ranging from read/write issues to distorted screen images. b> Identifying a Bad Capacitor b> To identify a bad capacitor you will need to open your computer case and locate the capacitors on your motherboard. A bad capacitor may exhibit swelling at the top or the base of the capacitor or it may sit at an awkward angle with the motherboard, so compare the various capacitors in your computer in terms of and placement. Additionally, a bad capacitor may have a funny smell or it may have a brownish residue leaking from the top or the base. b> Prevention b> Manufacturers claim that capacitors may go bad because a computer is not receiving enough power from a power supply, because of an overclocked processor or because a computer is operating in an environment with too much heat or humidity. However, some capacitors prematurely fail due to faulty work on the part of the manufacturer. If you have a bad capacitor be sure to do research as to the lifespan of other products made by your manufacturer.

SOURCE: my dell c640 will not boot

Ok, I question the virus theory due to the fact that your computer is overheating although it isn't impossible. There is a huge possibility that it is hardware failure or error as well. Try the other solution and see if that fixes it. Regardless of whether it does or doesn't, take a look at the hardware components in control panel.

(in case you don't know, here is how to check)

  • open control pannel in classic view
  • click on administrative tools
  • click on computer management
  • click on system tools
  • click on device manager
In device manager, there is a list of all the components that are possibly in the computer. If you click on them, they will tell you the status and will give you the option to diganose. If you want to do this to the main components such as processor, ram, etc, this might tell you if something is wrong. This is a rare time where I can actually say that it is unfortunate that you do not have vista. It has an extensive testing and report of the system performance that would help you very much. If you don't find anything there, you are very limited in other options. I can take a look and see if I can find anything else that may help you, but unless you want to open your computer up, you would have to get some software that could scan and do a performance check on your computer. Of course, this is assuming it isn't software related such as a virus. If all else fails and this and virus check doesn't work, about all that is left is the repair shop. Well actually, you could always try to whipe your hard drive and start over but that is quite the process and isn't fun at all. Well, I hope that this is a fixya or at least was helpful and informational. If so, please rate well. This is the only way we get paid for free questions like these. :) Have fun!!!!

p.s.
If you have any other questions, feel free to ask me.

SOURCE: My Toshiba Satellite A75-s206 shuts down by itself.

I own one and just came across the best solution.  I'm assuming by shuts off, you mean it just completely blinks out in an instant without warning - this is the processor getting too hot and shutting off to protect itself.  First you will make sure the fan & heat sinks are clean and working properly, then you will enable the power management features of the processor (Toshiba's power utility does not do this).
First, of course, get the canned air and blow out all the fans and heat sinks so they can work properly.
Next, download and install the RightMark CPU Clock Utility (search google for it).  It will take a little reading up to figure out how to use it, but here's the basics: 1. Go to the "profiles" page  a. under "Profile Selection" set it to use "Performance on Demand" for both AC power and battery (current and startup).  b. Then hit the "Defaults" button at the bottom, and then hit "Apply" 2. Now, expand the "profiles" tree (on the left side, there should be a little + next to it) and go to the "Performance on demand" profile and do the following: a. Click the "CPU Settings" button at the top. b. Hit "Defaults" at the bottom of the page c. For both AC power and battery, check "Use throttling", and then check all the indexes (0-7) in the list below. d. Below that, set the "target CPU usage level" to 75%. e. Hit "Apply"

If that all works properly, you should be able to go to the "Monitoring" page and watch your processor throttle up and down automatically as needed.  You should find that within a minute the fan gets a lot quieter because the processor is so much cooler.  Now that it's running properly, you can open the "Settings" page and check the boxes "start minimized to system tray" and "Run at windows startup", now it will run completely automatically, you won't even notice it except the fans will be quieter and your battery will last longer.
What it does: this laptop uses a Pentium4 processor, and by default WindowsXP does not manage the processor power settings on "desktop" processors.  Toshiba's power utility also does not manage these settings very well, so your processor is always running near full power no matter if it's playing a video game or just editing a text document.  The RightMark utility automatically adjusts the processor's clock speed, operating voltage, and throttle according to how much speed you need at any given moment.

SOURCE: sudden shut down

You probably have a clog of dust between the fan and the heatsink. It would be best to have it disassembled to clean, although a few models have clean-out doors to the fan on the back. You might be able to somewhat clear it by blowing canned air in the vent, but this may push dust balls into the fan that go right back against the heat sink.

SOURCE: my acer extensa 4420-5963 gets really hot and

It could all be down to the heat problem.

Check the fan housing, is it clear of dust. If not there is usually lies the problem.

When using the latop, ensure its on a flat surface so the air can circulate around the vents and fans.

  • There is a possibility that the fan of your laptop is not working. Make sure when you power on the laptop the fan is running. And if the fan is not working replace it so that your laptop will not heat up and it will not shut down.

Help !!!!my laptop shuts down


We had some Acers do the exact same thing and we fixed them. I believe it shuts right off as a safety. Usually when the processor gets too hot it powers right off to save the laptop from burning up. First quick fix it to blow out the vents and especially blow out the heat sink vent. Also could be that the heat paste that sits between the CPU and Heat Sink could have dried up and stopped doing it's job to remove heat efficiently from the CPU. Big problem in earlier model Gateway laptops too. This can be fixed by acquiring some paste from a local tech shop and reapplying it. If you feel unsure about it, take it to a tech shop and they can do it quick for cheap if not for free. Keep me posted - Scotty
