Prevent your laptop from overheat in Summer

One drawback of laptops is overheat. With a shrinking size, all laptop manufacturers make laptop with thermal materials to keep the balance between power and temperature.

At the risk of offending the manufacturers, it seems obvious that they not always get that balance.Most notebooks like (HP pavilion dv5 battery) have serious temperature problems, and more so at this time of summer, as the temperature does not help cooling. Here are some tips from www.batterystore.co.nz for your computer, and by extension your laptop, not like a steak roast.

Keep free ventilation

Though small and well camouflaged, there are many vents. It is vital to ensure that your Dell inspiron 15 battery have a free method to expel hot air. Otherwise, the computer will become an oven.

The laptops are designed for use on flat surfaces, leaving a small space for such grids (thanks to the feet.) If you put the laptop on a soft surface like a blanket, the legs go down, and the ventilation is blocked.

Cleaning laptop

It is pointless for the grids have a free hand if they are blocked with dust and dirt. A regular basic cleaning and help keep your HP pavilion dv4 battery cool and running like a charm.

If you are not going to use for a while, keep it stored where it can not catch dust. If you have a furry pet, do not let the hair rampant through your house. A vacuum cleaner can help remove the hair that may have been introduced to the fans. If you’re brave enough, you can open the computer and clean it thoroughly, and here’s how.

Laptop Cooling Stand

The use of cooling stand is almost obligatory in most cases, they can reduce the HP pavilion dv8000 battery temperature around 10 degrees or so. Unfortunately, the quality often leaves much to be desired. Avoid buying “cheap” cooling stand because it will break soon after out of the box.

Note that larger diameter fans make less noise, but probably cover less space than two smaller ones. In essence, there are two kinds with different characteristics: plastic and metal (the first is cheaper, the second looks better but can become a pan).

Energy Saving

As you use your Dell inspiron 1440 battery computer, it is inevitable that this warms. We will not ask you to stop using it, but you can minimize the time it is on, energy-saving setting Windows to turn off the screen, suspend or hibernate after a certain period of inactivity.

In the article on how to increase your battery life and we provide some recommendations and programs for a more efficient energy consumption. Everything is summarized in the maxim “Let him rest when not in use.”

Less CPU usage

Laptop computers are smart: if they do not need all the power, not use, saving Dell inspiron 1545 battery power and also winning in freshness. Although these machines are almost as powerful than desktop computers, make the most of the graphics market last game under the sweltering heat of summer, it is probably the last thing you can do with it.

The more your HP pavilion dv9000 battery computer has to work hard, earn a higher temperature. A powerful graphics card is usually a time bomb in terms of temperature, and the same will happen if your hard drives have to constantly work overtime.

In short, keep a laptop cool is not easy. Common sense, a laptop cooling stand and reduce some of the monitoring programs that we saw in the selection of programs for laptops will be helpful.

What causes laptop batteries to overheat?

July 11th, 2010

In conjunction with the United States Consumer Product Safety Commission (CPSC), Dell and Apple Computer announced large recalls of laptop batteries in the summer of 2006, followed by Toshiba and Lenovo. Sony manufactured all of the recalled batteries, and in October 2006, the company announced its own large-scale recall. Under the right circumstances, these batteries could overheat, potentially causing burns, an explosion or a fire.

To understand why that happened, it’s helpful to know a little bit about how batteries work. Laptop Batteries have a negatively charged terminal and a positively charged terminal. In a battery, energy from electrochemical reactions causes electrons (negatively charged particles) to collect at the battery’s negatively charged pole. Charged particles are attracted to opposite charge, so if you connect a battery to a circuit, the electrons will flow from the negative pole, through the circuit and to the battery’s positively charged pole. In other words, the battery generates a moving charge, or electricity. (See How Electricity Works and How Batteries Work for more details).

The exact reaction that generates the electrons varies, depending on the type of battery. In a lithium-ion battery, you’ll find pressurized containers that house a coil of metal and a flammable, lithium-containing liquid. The manufacturing process creates tiny pieces of metal that float in the liquid. Manufacturers can’t completely prevent these metal fragments, but good manufacturing techniques limit their size and number. The cells of a lithium-ion Pavilion DV6000 battery also contain separators that keep the anodes and cathodes, or positive and negative poles, from touching each other.

If the Acer Aspire One battery gets hot through use or recharging, the pieces of metal can move around, much like grains of rice in a pot of water. If a piece of metal gets too close to the separator, it can puncture the separator and cause a short circuit. There are a few possible scenarios for what can go wrong in the case of a short circuit:

If it creates a spark, the flammable liquid can ignite, causing a fire.

If it causes the temperature inside the battery to rise rapidly, the battery can explode due to the increased pressure.

If it causes the temperature to rise slowly, the battery can melt, and the liquid inside can leak out.

- There are several reasons why- multiple Dell laptop battery models have been recalled in the past few years. People want small, lightweight laptops that they can use for long periods. They also want their laptops to have bright screens and lots of processing power. For these reasons, laptop batteries have to be relatively small, but they also have to hold a lot of energy and last a long time.

Making lithium-ion laptop battery that can hold more power for a longer period requires vital components, including the separators, to be small and thin. The reduction in size makes it more likely that the VGP-BPS2 batteries can fail, break, leak or short circuit.
