A laptop is an integral part for many of us for some reason or the other. While the office executives make use of it for performing their duties even while on the move, the housewives and students make use of it to search the Internet or valuable information for miscellaneous purposes.Let us study some of the numerous benefits of a laptop over the traditional desktop computers. A laptop offers higher levels of portability, flexibility, reliability and is space-conscious. The emergence of new market players, intense competition, falling price, higher levels of customer satisfaction and favourable market trends have all contributed to the growth of the laptop market in the recent years.The modern day cheap laptops offer exceptional solutions when it comes to complex needs, high-quality image resolution, viewing angle and contrast ratio. Most of the latest laptops score heavily when it comes to satisfying the ever-growing needs of their users.If you are planning to buy a fresh or second-hand laptop, you must consider some critical factors such as performance, price, substitute products, prevailing market trends, customer service and brand awareness. You must demand the original bill and warranty documents from the vendor and stay away from the grey market. It is of no use to buy the cheap laptops and regret at a later stage. Do not get lured by false promises and tall claims of profit-motivated vendors who leave no stone unturned to get easy and innocent customers.Some of the leading names in the world of cheap laptops are Acer, HCL and Compaq. The advanced and stylish Acer laptops such as the Acer Aspire 5583WXMi, Acer TravelMate 4233WLMi, Acer TM 6292 and Acer Ferrari 1005WTMi offer complete value for your money.

How Does a Laptop Battery Work?
There is little difference in how a laptop battery works and how other device batteries work. The batteries that power your portable CD players, radios, camcorders etc. are more or less the same except that a laptop battery is more intelligent if you can call it that. Just like the rest of the batteries, laptop batteries too come in different shapes and sizes with the addition to a complex electronic circuit that works in conjunction with the laptop hardware. This electronic circuit manages the power that flows into the battery while recharging and the power that flows out of each cell of the battery while discharging, a feature that is not included in ordinary rechargeable batteries for other household devices.Just like any other battery there are cells inside a laptop battery. Each cell is typically 1.5 volts and a number of cells are arranged in series and connected in parallel to deliver optimum power to the laptop or device. A number of cells are connected together to forma a battery. Connecting a number of cells in parallel means to connect all the negative terminals to each other and positive terminals likewise this increases the power delivering capacity of the battery but not the voltage. Then a number of these batteries are connected in series (negative to positive terminals to raise the voltage). This is done to optimize the voltage level of the battery. These cells are controlled by an internal electronic circuit in the battery.The internal electronic regulator is the unique property of a laptop battery. This circuit regulates the flow of charge into and out of each internal cell in the battery thus ensuring that each cell has an equal charge at all time in turn ensuring the optimum use and long life of each cell. It also ensures that the cells do not over charge.The plates of each cell react with the electrolyte (chemical/acid) in the battery causing a flow of electrons from the negative to positive terminals and a flow of ions from the positive to the negative terminal this is the flow of current as we know it. This flow continues until the electrolyte loses its acidity. When the battery is charged the ions are restored to their place in the cell and the electrolyte regains its acidity ready to generate electricity in the cell once again. This process is always the same irrespective of the type of battery. The process of charging or discharging of the battery is controlled by hardware built into your laptop. This hardware ensures the proper functioning of the cells in the battery and warns you of the tile left before you need to recharge the battery. This indicator is displayed in the right bottom corner of the screen in most notebooks or laptops. Though the laptop battery is rechargeable, like everything it does have a life span and cannot go on serving you for eternity. Proper care will ensure that the battery lasts longer than it would without the proper care. A battery will normally last between 500-700 charge cycles before it will need to be replaced with a new one. The number of charge cycles of the battery will depend on the usage of the laptop. The more often you need to charge your laptop the sooner you will have to replace the battery. Every laptop model is designed to suit a particular function and so is the battery designed to match the power requirements of the laptop. The design of the battery depends on the weight and size of the laptop. A small light-weight laptop will have its design defeated if the battery weighs more than the laptop itself, so the battery has to be designed to suit the model of the laptop.

The Little Chill
Dime-sized fan is ready for testing as cooling system for laptop computers.
May 1, 2008 -- Researchers are ready to test a miniature device they say will help laptop computers and other electronic devices chill out. The compact, solid-state fan -- only slightly larger than a dime -- produces three times the flow rate of a typical small mechanical fan at one-fourth the size, according to the National Science Foundation (NSF). The NSF's Small Business Innovation Research (SBIR) program provided support for development of the fan.
count = 'square300' + ++square300count;randomness = Math.random() * 100000;
document.write('')
More specifically, the device creates an air flow of 2.4 meters per second. It's being touted as a "silent, ultra-thin, low-power and low-maintenance" solution to the heating problems that plague laptops. "This technology has the power to cool a 25-watt chip with a device smaller than one cubic centimeter and can someday be integrated into silicon to make self-cooling chips," says Dan Schlitz of Thorrn Micro Technologies.
The RSD5 solid state fan is the result of six years of work by Schlitz and fellow researcher Vishal Singhal, also of Thorrn Micro Technologies. It incorporates a series of live wires that generate a microscale plasma (an ion-rich gas that has free electrons that conduct electricity), according to the NSF. The wires lie within uncharged conducting plates that are contoured into half-cylindrical shapes to partially envelop the wires. Within the resulting electrical field, ions push neutral air molecules from the wire to the place, generating a wind.

Laptop
A laptop computer, or simply laptop (also notebook computer, notebook and notepad) is a small mobile computer, typically weighing 3-12 pounds (around 1.3 to 5.4 kilograms), although older laptops may weigh more.
Laptops usually run on a single main battery or from an external AC/DC adapter that charges the battery while also supplying power to the computer itself. Many computers also have a 3 volt cell to run the clock and other processes in the event of a power failure.
Laptops contain components that are similar to their desktop counterparts and perform the same functions, but are miniaturized and optimized for mobile use and efficient power consumption, although typically less powerful for the same price. Laptops usually have liquid crystal displays and most of them use different memory modules for their random access memory (RAM), for instance, SO-DIMM in lieu of the larger DIMMs. In addition to a built-in keyboard, they may utilize a touchpad (also known as a trackpad) or a pointing stick for input, though an external keyboard or mouse can usually be attached.
