A laptop comparison

1. Best laptopsIn recent years, the laptop is becoming more important in the field of computing. Now, for the first time, its sales have surpassed those of desktop computers in the United States. Between netbook and notebook, the choice remains to be done.

Here is a comparison of computers :
2. All-in-One, Ultra, or design, your PC at the right format!
It is important to target the size of the laptop based on the use you make of it. This goes along with the size of the screen. Do not be tempted by a big screen if you plan to travel regularly.

3. Beware of the weight
If you intend to travel regularly, pay attention to the weight of your machine. Above 2 kg, the computer is less mobile because, added the weight of accessories, the bag and many other items that will quickly make it hard to move with .

4. The autonomy, essential for the mobility
Autonomy is a very important criterion. In fact, if you plan to use your computer anywhere, it must have a good autonomy. Several parameters are taken into account. The screen first: the larger it is, the more it consumes energy, and the computer is less durable. It’s the same for the graphics card. When integrated, the autonomy of the system is improved. However, if a dedicated graphics card, it may consume a lot .

For the processor, it depends on the heat it releases, otherwise known as TDP. Over this data, the lower it consumes. Batteries: the more they contain “cells”, the more they allow a good autonomy. Finally, choose the right compromise between the number of cells, the price of the machine, its components and its weight.

5. Hard disk: capacity and performance
Beware, it’s not just the ability that matters! If 80 GB is now a minimum for an acceptable comfort, hard drive running at 4200 rpm is too slow to provide decent benefits and has virtually disappeared. Currently, the standard is around 5400 rpm (make-in). The disks for laptops 7200 rpm represent the high end and provide for the use, approval and additional significant. Some manufacturers also add functions to protect data against accidental bumps . In 2009, we must also take account of the democratization of the DSS, this format storage device based on flash memory. Still expensive, this system offers improved performance in access time, reading and writing.

6. What processor for common use?
Today, all processors in the market are sufficient for common tasks such as office, internet surfing, watching movies, MP3 files or photos. The difference between a high-end machine and a machine input range is mainly due to comfort (responsiveness and multitasking) and the autonomy of the service.

7. What processor for advanced use?
The games, but also video editing, HD playback or 3D graphics require powerful processors. In the field, the Intel Core 2 Duo is now a must because of the strength of its two cores combined with autonomy authorized by the intelligent management of consumption. The latest Intel Centrino 2 platform will be on a plus in this case.

8. A quality keyboard for comfort
It is impossible to replace a keyboard on a laptop, so be sure before buying it that the keyboard has a good quality, the keys are well laid out and the touch is enjoyable. Likewise, the touchpad should be balanced, and sensitive keys click as failing rapidly transforming the everyday into a nightmare. Only tests on products can give you an idea.

9. How much memory (RAM) is needed?
It takes at least 2 GB of RAM for use with Vista basic or intensive (several programs running at the same time) with XP. For games or for more comfort and responsiveness, it will also have 2 GB in Windows XP . Recall that under Windows, only a 64-bit OS handle more than 3GB of RAM.

Dedicated or integrated graphics cards ?As part of a standard use, all the chips on the market agree. For  gamers and graphic designers to manipulate 3D objects, the presence of a  dedicated graphics chip, with its own video memory (256 MB of RAM) is a  virtual requirement.
