some older portable computers

February 9th, 2010 by zhangyan787

A  Laptop Battery  computer or simply laptop (also notebook computer or notebook) is a small mobile personal computer, usually weighing from two to six pounds (one to three kilograms), depending on size, materials and other factors.

  While the terms “laptop” and “notebook” are often used interchangeably, “laptop” is the older term, introduced in 1983 with the Gavilan SC. “Notebook computer” is a later coinage, which was used to differentiate smaller devices such as those of the NEC UltraLite and Compaq LTE series in 1989, which were, in contrast to previous laptops, the approximate size of an A4 paper sheet.[1] Either term is often used improperly: due to heat and other issues, many laptops are inappropriate for use on one’s lap, and most are not the size of an A4 sheet. Although, some older portable computers, such as the Macintosh Portable and certain Zenith TurbosPort models, were sometimes described as “laptops”, their size and weight were too great for this category.

  Laptops usually run on a single battery or from an external AC/DC adapter which can charge the battery while also supplying power to the computer itself.

  As personal computers, computer battery  are capable of the same tasks as a desktop PC, although they are typically less powerful for the same price. They 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. Laptops usually have liquid crystal displays and most of them use different memory modules for their 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.

  Terms sometimes used for subtypes of laptop computers include:

  Ultraportables

Laptops with screens typically less than 12 inches diagonally and a weight of less than 1.7kg. Their keyboards are usually not full-size. Their primary audience is usually business travelers, who need small, light laptops. Ultraportables are often very expensive and house power-saving CPUs and almost always have integrated graphics.

Will be able to get the most out of your  Laptop.

Step1

If you are not using the internet turn off your wifi connection and lower the intensity of your backlight (hold down function and move the arrows up or down to change intensity).

Step2

Don’t leave your computer plugged in constantly when it is not in use. If your computer always relies on this power, it will loose its ability to last long on its own. So always charge your computer when the battery is almost dead and then unplug it from the wall.

Step3

Keep your computer in a well ventilated place and keep it cool. Your battery works faster when it is hot because it is creating more energy and is burning out faster.

Step4

Try to avoid turning your computer on and then off constantly. If you turn your computer on in the morning, leave it on until you are done with it for the day. You can put your computer into sleep mode throughout the day if you like.

Step5

Always use the correct Laptop Battery for your laptop. Don’t try to use some other source of power. This will do nothing but destroy your laptop.
