How to choose a laptop?

Due to the design features of the laptop upgradepractically impossible. It can not replace the motherboard or graphics card, there are limited opportunities to increase the operational or disk memory. In addition, laptop repair is more complicated and more expensive than a desktop computer. Therefore, when deciding on the purchase of a laptop, you should very carefully approach the choice of the model.

By and large, the difference between the sameparameters notebooks of different manufacturers if there is, then a small one. The consumer pays more for the high-profile name of the manufacturer and its quality assurance than for the technical "bells and whistles." Therefore, before you grab the first popular model of the laptop, you should find out what characteristics it has, what tasks it can solve.

Important criteria for choosing a laptop are its weight, dimensions, usability and, of course, performance. Priority of this or that criterion is determined by the purpose of the laptop.

So, if laptop is designed for office work, then what is most important in it? Such a laptop, you probably do not have to often wear in your hands, it does not need to "pull" heavy 3D graphics or movies. Basically on such a laptop it is supposed to work with text editors and other programs that do not require a lot of resources.

Therefore, a laptop for office work may not be very productive - enough clock speed of the processor, equal to 1 GHz. In this notebook the video card can be integrated, because it does not have high requirements.

Laptop Keyboard for office work should be easy to set uplarge amount of text. In laptops, the keyboard, as a rule, is slightly different from the usual "desktop" ones. Functional or even some "alphabetic" keys are located in laptops not like on a traditional keyboard, so it can be very difficult to get used to a new layout.

For convenient work with text, small screens do not fit, it's better to choose a model with a diagonal of 14-17 inches. But these laptops weigh more than they dowhich have a smaller diagonal. Therefore, if you still expect to carry the laptop all the time in your hands, then it's better to give preference to models with a smaller screen, but also with less weight.

For an office laptop is important presence of the most necessary interfaces and ports: modem, LAN, Wi-Fi, Bluetooth, USB 2.0 and VGA. Also, an office laptop may need a card reader for reading expansion cards.

If you intend to work with optical drives, it is important presence of a drive for reading / writing CD or DWD disks. In small models, weighing up to one and a half kilograms of this drive may not be.

The possibility of autonomous work is the most important advantage of a laptop in front of desktop PCs. Therefore, attention should be paid to laptop battery capacity, the higher it is - the longer the laptop can work offline.

If you select a laptop for working with 3D-graphics or modern games, then the processor and graphics card are presentedhigher requirements. You should pay attention to the clock frequency of the processor - it should be at least 2 GHz. To reproduce complex three-dimensional graphics in graphics editors or games, you need more video memory and a more efficient graphics processor, so the built-in graphics adapter is not suitable.

3D applications are very demanding on system resources, so you need to choose a laptop with the maximum amount of operational and disk memory.

A notebook on which plans to strengthen the work with multimedia, should have a high-quality display with high resolution, which gives clear images, does not distort colors, does not "glare".

Another rather significant parameter when choosing a laptop is preinstalled operating system. On expensive models, manufacturers installpopular OS, for example, Windows or MacOS. These operating systems are paid and, as a rule, their cost is included in the cost of the laptop. There are also laptops in which a free system is preinstalled (FreeBSD, Linux, etc.) or a trial version is installed for a limited period. Such models will cost a little less.
