When buying a laptop, in addition to the choice of material, or a brand or specifications, it is recommended to ensure the following:

Weight: laptop will clearly be transported, so it is very important to choose the light possible. Be careful, however, sometimes the weight without external devices like DVD Writer.

Autonomy: The autonomy of the computer is directly dependent on the use of its components and characteristics of the battery.

Type Ni-MH battery: more powerful than nickel-cadmium batteries.

Type Li-Ion battery: rechargeable batteries are installed in most laptops. In Li-Ion batteries offer excellent performance at low cost. In addition, Li-Ion batteries do not suffer from memory effect, which means that it is not necessary to empty the battery completely before recharging device.

Type Lithium-polymer battery has a performance equivalent to lithium-ion batteries, but much lighter, as the liquid electrolyte (or ion solution), and micro-porous separator of the lithium-ion battery, replaced by lighter solid polymer (polyacrylonitrile). However, this type of battery is not an asset, because charging more, and their life is relatively low. It usually defines the autonomy of your notebook for the average time of activity a laptop in standby / usage.

Operating temperature: Different components of a laptop work leads to an increase in temperature, which sometimes can be very high. Overheated may seem, especially when the laptop is working with the screen closed, as this can prevent good heat (Joule effect).

Noise: In some models of laptop computers, fans, used to heat can be very noisy. In addition, in the case of the motors driving the rotating hard disk drive or CD / DVD. He strongly encouraged to seek information about the level of noise from the computer when it works.

Notebooks more practical than desktops. You will be able to work wherever you go, and it can be fun. Perhaps you will spend a little more than one table, but if you want to save some money is always restored laptops offer.
