How to choose a laptop?

CongestionTransportableIf you really do not need mobility, that is to say that you do not move constantly with your machine, you will not work in unlikely places, there is no need to buy a small laptop . Choose a somewhat larger model, but with a large screen (17 "or 18"), a separate numeric keypad and a large battery then is a good choice in terms of comfort.WearableYour computer must be able to follow you around but you need a minimum of comfort. "A 15.4 only and is not so bulky. Weight is reasonable and comfortable keyboard.Mini LaptopMini laptops are very small computers. Miniaturization, better still, components used to manufacture high-performance computers less than 1 kg with all the features of a PC is expected. These machines can be stored in a small bag and use it anywhere. Interesting for a great need for mobility, frequent travel or work anywhere.SpecificationsProcessorThis is the heart of the computer. The machine performance is greatly conditioned by the performance of the processor. More is desired to many software and powerful applications using different media operate more we will need a powerful processor (frequency> 2.4Ghz). However, for desktop or Internet use, one can afford to choose a mid-range processor (frequency = 2 GHz). They are powerful enough to effect a smooth operation of the computer.RAMAlso known as RAM, memory that temporarily stores data during processing by the processor. More RAM capacity is more important the processor will have quick access to the data it needs to process. 1 GB of RAM seems to be a great day minimum. Microsoft even recommends 2GB for Vista to use effectively. Most phones have now come with 4GB of RAM. For portable mini can just 512MB since will not use too intensive applications.StorageLaptops hard drives today show a very honorable capacity up to 500GB. This is important and should be before buying well determine how much storage space you will need. But size is not everything and we must take into account the speed of access to stored data. A hard drive running at 7200 rev / min will be more powerful than a 5400 rev / min. Some computers now offer a flash or SDRAM. Unlike the hard drive, this storage method does not implement any mechanical element and is therefore less fragile. However, it is more expensive, does not yet offer a very large area (up to 16GB) and have a limited life.Graphics cardThis is key if you play video games or guzzling 3D animation in this regard. Do not hesitate to take a powerful graphics card as they become obsolete relatively quickly. It is therefore recommended that a card with 512 MB of dedicated video RAM, combined with a sufficiently powerful graphics processor, see choose the graphics card of his mobile.
Otherwise, it may be interesting to have a TV output on the laptop but the high performance of the graphics card will not necessarily needed. Moreover, the mini laptop and some entry-level models offer just one graphics chipset (integrated into the motherboard chip), enough for the office or the Internet.ConnectorsTry to consider all the uses that we may make the machine and see what will need connections. Firewire particular is increasingly used for its performance (much faster than the USB data exchange). Also, do not skimp on the USB ports, always helpful (remember to check that they are sufficiently spaced to accommodate multiple devices). To view your recordings on a TV, so be sure to check the HDMI connection. A multipurpose card reader is also sometimes useful for transferring data from the device or pictures on his mobile phone.ScreenSizeIt is portable with screens ranging from 7 to 20 inches. The size of the screen depends on the use you want to make your machine. A large screen will pleasantly watch movies, work or play comfortably. However, the size will be larger and the weight. Instead a small screen from 12'' and less provides a very convenient to carry machine.BrightnessAs for the pictures on paper should choose matte or gloss. The brilliant promotes watching videos with close to a TV report. The mat it is certainly less enjoyable to watch but is less sensitive to glare. Again, the choice depends on your usage.AutonomyIt is 2 to 8 hours in office use. This is a key point in choosing a laptop. It is good to know that a more powerful battery is heavier it is. This must be taken into consideration if you need to carry your PC everywhere. We can play on the quality of the battery, but also on consumption. There are now low-power processors that allow machines to operate much longer in total autonomy. Look carefully at the manufacturers data (knowing that they are often a bit optimistic).Operating systemThis is certainly the most important. If everyone is upset with Microsoft OS, more and more low cost laptops come under Linux distribution to make savings on Windows licenses. The Linux system is fairly simple to use, but it must still allow time to adapt if it is your first trip outside Microsoft. Similarly, all applications are not compatible with Linux, even if there are software equivalents.Noise and heatWe often forget these parameters when choosing a laptop. Yet in practice, they often turn out leading in terms of ease of use. Computers warm and for that they are broken. Sometimes ventilation can be very noisy. Also, it happens that some machines run hotter than others. Check these settings before buying is often difficult, especially if you order online. It is safe to say that the higher the range unless these problems are important.WarrantyDepending on your level of computer experience, it may be useful or not to sign a contract that includes an on-site repair warranty or telephone support. In general, you can not change any part on a laptop, take a long warranty seems sensible. Unless you often change to be always on top.UpgradeOf course, one would like to do with your laptop the same thing with his desktop PC: replace some old components with more efficient. It is easy to add memory, it will not always be easy to change the hard drive, only some laptops will change the processor, let alone have a replaceable graphics card, so we must choose well from the purchase ...Know that there are specialty stores that you change the processor or graphics card if possible.
