When a person is looking to buy a new laptop computer, there are several features that need to be considered before the final purchase is made. With many different types of laptops on the market, it can be difficult deciding on only one to buy. The most common features to look for in a laptop computer are screen size, the amount of memory, hard drive size, battery life and processor speed. Each of these features is a big part of what makes a laptop worth buying and each one is equally important for potential buyers. The first thing to consider when looking to buy a laptop is the screen size. The three most common screen sizes are 11.1 inches, 15 inches and 17 inches. For users that are always traveling and need a laptop that is capable of Surfing the web and creating text documents, then the 11.1 inch screen may be the best choice. For users that do light traveling and primarily use their laptop on the couch, then the 15 inch screen will be good for watching videos and surfing the web. Laptops that have a 17 inch screen usually are for gamers and are far more expensive. The next thing that a person should look at when buying a laptop is the amount of RAM it has. A typical laptop will have between 2Gb and 4GB of memory. The amount of RAM will basically determine the number of programs that can be open at any one time. Without a sufficient amount of memory, a laptop will not be able to function properly. Another feature that people need to consider when buying a laptop computer is the battery life. Most laptops will have a battery life of two to three hours, while the more expensive models can have a battery that lasts up to six hours. Battery life is most important for people that rely on their computer while they are traveling. For people that are not going to take their computer out of the house, battery life is not important because it will stay plugged into a power source. Overall, there are a number of features that users should consider before buying a computer because many people regret their decision if they do not do the proper research.
