Toshiba suddenly shuts down by itself posted in: Overheating, Toshiba Problems | “My Toshiba laptop suddenly shuts down by itself without any warning. Sometimes it works fine for hours, sometimes it shuts down in 10-15 minutes.” This complaint we hear from our customers over and over again. About 15-20% of all Toshiba laptops we get for repair, suffer from an overheating problem. This is one of the most common problems with Toshiba laptops we deal with. Indications of laptop overheating problem: The keyboard and the bottom of your laptop are very hot when the laptop is working. The CPU fans are working all the time at maximum rotation speed and operate much louder than before. The laptop suddenly shuts down by itself without warning. When it just started, the laptop was shutting down after 1-2 hours and how it shuts down after 5-10 minutes of operation. The laptop works fine when it runs idle, but shuts down as soon as you start using any memory demanding applications (DVD player, image editing software, video editing software, etc.).

If the CPU heatsink is not clogged with dust and lint completely, you can use canned air and just blow it inside the laptop through the openings on the bottom and on the sides. air purifier window openIt’s nice as a precaution measure, but it might not work if your laptop already has a problem and the heatsink is completely clogged.auto air duct cleaner Open the laptop case, so you can access the CPU fan and the heatsink. air purifiers for artist studiosIn some cases you can access the heatsink through the latch on the bottom of the laptop. Sometimes you have to open the laptop case all the way down. Carefully disconnect the fan cables on the system board and remove the fan. If the fan makes unusual sound when it spins (grinding sound), I would recommend to replace the fan.

Clean the fan and the heatsink with compressed air. I would also recommend removing old thermal grease from the CPU and applying new grease for better heat conductivity. UPDATE: I just received a nice tip from MC N’Colorado. I think it could be useful for all of you with guys: I decided to use a shop vac to suck the dust out and it worked. I tested it by letting the machine run all night and it worked. It’s been a couple of weeks now and I’m glad I did it. I was ready to take the machine apart, now I’m glad I didn’t. I’d suggest you use a heavy duty shop vac to clean out the fan and heat sinks first.Try to fix the problem without taking the laptop apart first but I would recommend using a powerful air compressor instead of a vacuum cleaner. If your laptop is still under warranty, you can take it to any Toshiba Authorize Service Provider and fix the problem at no charge to you.

Gas duster, also known as canned air or compressed air, is a product used for cleaning electronic equipment and other sensitive devices that cannot be cleaned using water. Despite the name "canned air", the cans actually contain gases that are compressable into liquids. Air on the contrary, cannot be compressed into liquid at any pressure since the critical temperatures of air components (-146.9 C for nitrogen; -118.6 C for oxygen) are much beyond normal handling temperatures. Duster gases are such as 1,1-difluoroethane, 1,1,1-trifluoroethane, or 1,1,1,2 -tetrafluoroethane. Hydrocarbons, like butane, were often used in the past, but their flammable nature forced manufacturers to use fluorocarbons. When inhaled, gas duster fumes may produce psychoactive effects and may be harmful to health. Since gas dusters are one of the many inhalants that can be easily abused,[1] many manufacturers have added a bittering agent to deter people from inhaling the product.

Because of the generic name "canned air", it was mistakenly believed that the can only contains normal air or contains a less harmful substance such as nitrous oxide. However, the gases actually used are denser than air, such as difluoroethane. When inhaled, the gas displaces the oxygen in the lungs and removes carbon dioxide from the blood causing the user to suffer from hypoxia which results in the euphoric feeling abusers desire. This type of inhalant abuse can cause a plethora of negative effects including brain and nerve damage, paralysis, serious injury, or death. The liquid, when released from the can, boils at a very low temperature, rapidly cooling any surface it touches.[3] This can cause mild to moderate frostbite on contact with skin, especially if the can is held upside down. Also, the can gets very cold during extended use; holding the can itself can result in cold burns. Since gas dusters are often contained in pressure vessels, they are considered explosively volatile.

Global warming: Difluoroethane (HFC-152a), trifluoroethane (HFC-143a), and completely non-flammable tetrafluoroethane (HFC-134a) are potent greenhouse gases. According to the Intergovernmental Panel on Climate Change (IPCC), the global warming potential (GWP) of HFC-152a, HFC-143a, and HFC-134a are 124, 4470, and 1430, respectively.[4] GWP refers to global warming effect in comparison to CO2 for unit mass. 1 kg of HFC-152a is equivalent to 124 kg of CO2[5] Ozone layer depletion: Gas dusters sold in many countries are ozone safe as they use "zero ODP" (zero ozone depletion potential) gases; tetrafluoroethane, for example, has insignificant ODP. This is a separate issue from the global warming concern. Many gas dusters contain HFC-134a (tetrafluoroethane), which is widely used as a propellant and refrigerant. HFC-134a sold for those purposes is often sold at a much higher unit price, which has led to the practice of using gas dusters as a less expensive source of HFCs for those purposes.

Adapters have been built for such purposes, though in most cases, use of such adapters will void the warranty on the equipment they are used with. One example of this practice is the case of airsoft gas guns, which use HFC-134a as the compressed gas. Several vendors sell "duster adapters" for use with airsoft guns, though it is necessary to add a lubricant when using gas dusters to power airsoft guns. True "air dusters" using ordinary air are also available in the market. These typically have much shorter run times than a chemical duster, but are readily refillable. Both hand pump and electric compressor models have been marketed. The maximum pressure for an aerosol can is typically 10 bar (145 psi) at 20 C (68 F).[6] Therefore, a fully compressed air duster will exhaust air about 10 times the can volume. Recently electronic versions which only use air have become viable alternatives that are preferred by many large corporations due to the fact that they contain no hazardous chemicals, are safe for the environment, do not freeze and they cannot be abused by addicts looking to get high.
