Nowadays, desktop computer is getting replaced by laptop; it is also called as notebook or notepad and can be easily moved from place to place. It is a small mobile computer which is very much necessary for all the people like businessman, students, teachers and kids. As the necessity of it is being felt more, many companies have started producing more variety of laptops making it tedious for the people to select the right one. Usually a laptop weights two to eighteen pounds, which depends on the size, material and other factors. At the time of purchase of any laptop the basic features emphasized by any customer are its processor type, the storage capacity, screen size, battery type and its longevity, price differences, wireless connectivity and more.
Laptop runs on a single main battery or it can be charged using an external AC adapter and it can also supply power to the computer. In case of power failure the laptop can run for one full day using three volt cell. A laptop is a miniature of desktop and it is capable of many tasks like desktop, but with less power consumption and it can perform all the functions of a desktop, but it is best for mobile use and for efficient power consumption. Compared to Desktop, laptop can perform all the tasks, but t is less powerful, even though if it is of same price. The display of laptops is usually of liquid crystal and the memory models used are different according to the random access memory (RAM). Added to a built in keyboard, a touchpad or trackpad can be used and in addition to that an external keyboard or mouse can be attached.
In early 1970's, laptop computers were technically viable and matching ideas had been proposed by Alan Kay's Dynabook concept which was developed at Xerox PARC. But, the first commercially available portable computer was manufactured in 1981, but it was very large and heavy compared to laptops existing today. And the research process keeps on going and so many types of laptops have been designed and manufactured with different configuration. Laptops are energy efficient and are more compact than the desktop as the components are much bigger in the desktops.
As the manufacturers are different and each and every one of them have their own systems and method. Till date there are no firm worldwide standards relating to laptops internal form factors such as supply of electric voltage, motherboards layouts, and internal adapters used to connect the hard disk, optical drive, keyboards, LCD cable, floppy drive etc. Some parts like hard drives and memory are the items that are interchangeable, but motherboards, keyboards and batteries are only interchangeable within the manufacturers brand or model. Physical damages are more likely, compared to desktop, as they are portable and components like batteries, screen hinges, power cords and power jacks might get weakened due to ordinary use. Even though if a liquid spell on to the keyboard it is a minor mistake but it can damage costly components such as motherboard or LCD panel. Dropping a laptop can break the glass LCD screen. In case of failure of motherboard or LCD panel, the repair charges exceed the value of the laptop. These are some of the disadvantages of using Laptop.

By: Anne | 14-07-2008
Hi, I have a Dell Inspiron 1100. When I loaded Vista Ultimate on my laptop my desktop shrank and is half the size of my laptop screen. It is about the size of a card envelope. If I try to change the font size or the resolution it will fill up the screen but is not readable and there is no color. I remember I had a problem like this when I loaded xp and think I downloaded a new driver but don't remember what it was. Help please and thanks in advance.
