At the time of the purchase of your next laptop, in addition to the choice of the material elements, it is highly advised to take care of the following characteristics:
The weight: a laptop is made obviously to be transported, consequently it is essential to choose it lightest possible. Be vigilant all the same with the light portables of which the main part of the peripherals is external.
Autonomy: The autonomy of the computer east depends directly on the consumption of its components as well as characteristics of the battery. The type Nor-Mh: type of refillable battery of a portable PC more powerful than the batteries Cadmium-nickel.
The Li-Ion type: type of refillable battery equipping the majority with the laptops. The batteries Li-Ion offer excellent performances at a modest cost. Moreover the batteries Li-Ion do not suffer from the ratchet effect, which means that it is not necessary to completely empty the battery before reloading the apparatus.
The type Li-Polymer: type of refillable battery having performances equivalent to the batteries Li-Ion but much lighter insofar as the electrolytic liquid (or ionic solution) and the microporous separator of the batteries Li-Ion is replaced by a solid polymer (polyacrylonitrile), much lighter. However this type of battery is not the panacea because the time of load is more important and their lifespan is relatively weak. One generally defines the autonomy of the laptop by the average time of activity of the laptop in day before/use.
The Operating temperature: The operation of the various elements of a portable PC involves an increase its temperature sometimes being able to be awkward. It can exist a danger due to overheating, accentuated in particular when the laptop functions with the closed screen, because this one can prevent a good thermal dissipation (Joule effect).
Noise: In order to dissipate heat due to the operation of the whole of the elements of the laptop, they are sometimes equipped with fluidic devices of heat such as ventilators, being able to create an important auditive embarrassment. It is also the case for the engines involving the rotation of the hard drives or the reader of CD/DVD. It is strongly advised to get information about the noise level of the computer when it functions.
