If you are thinking this holiday season give someone a a notebook that tine we all know the benefits of that is mobile, takes up little space on the table and is easy to store. However, for most people, buying a notebook is a high investment. So then we offer 10 tracks to choose the right notebook:

1 - Memory

For the choice of the amount of memory, you should consider the current market standard. For example, we know that to run Windows XP or a recent Linux distribution using KDE or Gnome graphical environment, it is important to have at least 256 MB of RAM. However, it is best to have 512 MB of memory to not affect performance. Therefore, always choose a notebook that has memory capacity to comfortably run the software you use daily in their work and to allow for future expansion.

2 - Processor

As for the processor, it is necessary to choose the most powerful (but also not recommended a lower to 1.2 GHz), but it is necessary that the processor has means of saving energy, as the models of the Pentium M, Intel (AMD also offers processors for notebooks, but it is more difficult to find). These processors have the ability to save power when certain resources are not being used. Besides helping to prevent the heating, this feature makes the battery last longer.

3 - Battery

In cell phones, PDAs and notebooks mainly, was not yet possible to develop a type of battery that lasts a considerable time. Either way, choosing the right technology can add more usage time. Currently we recommend the use of battery type lithium ion battery. These usually have a charge longer, a longer life cycle and do not add significant cost to the price of the notebook. An important detail: if you need to use the notebook with the battery constantly, it is advisable to purchase a model that will add an extra battery. There are models of this type that have room for an extra battery or allow extraction of the CD / DVD to fit the new battery.

4 - Hard Drive

Notebook hard drives are smaller than those used in PCs: 2 "and 3.5" respectively. This feature makes hard drives for laptops are usually a little more expensive than disk for PCs. Therefore, choosing a high capacity hard disk should be considered only if necessary, in order to avoid major increases in the cost of the notebook. Note that you should not choose a model with little capacity to economize thinking, because if the hard disk was discontinued (or close to being discontinued), its price may be lower than a higher capacity disc. Even so, choose a 40 GB drive instead of a 20 GB, for example. Important detail: to reduce energy consumption, is common to have slower notebook drives for the disks for PC. While a current common disk rotates at 7,200 RPM (revolutions per minute), there are notebook drives that spin at 4,200 RPM or 5,400 RPM.

5 - CD / DVD

Today it is ideal to have a notebook with CD and DVD. The price difference between this device and one that only reads CD is negligible. Beyond that, consider that most of DVD players also recorded CD, which becomes a worthwhile choice. The devices that record DVDs are more expensive, so you should discuss your needs whether it is necessary to invest more money to buy it. As for the floppy drive, this type of storage is increasingly obsolete. With the popularity of pen drives, flash memory cards, rewritable CDs and DVDs, have a floppy drive is feasible only in very specific situations. For these cases, it is recommended to buy a external floppy drive.

6 - Display

Obviously, the larger the screen, the better the display. However, the larger the screen, the greater also is the size of the notebook and its price. For that reason, the choice of screen size must be consistent with their needs. If you want a notebook for use at home to save space, a large screen is recommended. If on the other hand, is to carry the notebook to various locations (eg, visiting customers), a smaller screen helps to reduce the space occupied in the notebook bag. Another important choice to make in relation to the screen is your type. Choose screen monitors that use active matrix (TFT), because this guy has better picture quality compared to passive matrix displays (DSTN).

7 - Motherboard video

Maybe you will not run games on your notebook, but you probably will want to watch videos - for example, during a trip. Stop watching videos or even some games, you should choose a notebook with a good video card. In this case, it is important to check if the memory of the video card (VRAM) is proprietary - UMA (Universal Memory Architecture) - or is shared with main RAM - SMA (Shared Memory Architecture). If you choose a shared notebook that has at least 512 MB of RAM. If you choose teams with exclusive VRAM is recommended that the VRAM has at least 64 MB capacity.

8 - cursor device

This is an important detail: what kind of technology to use as a replacement mouse? The touch pad is a type of device where the user moves the cursor on the screen through the motion of the finger on a small touch-sensitive panel. The touch pad is usually accompanied by buttons which have the same functions as the keys of a common mouse. However, it also can simulate mouse clicks by tapping your finger quickly on the panel. Another option is the Pointing Stick, a small button that is between the keys of the notebook, which possesses a flexibility that allows movement of the cursor according to the pressure the user applies it across your finger. Choosing the best arrangement is complicated because it is a matter of skin. Therefore, it is best to try every option before buying a notebook or buy a team to make use of both technologies.

If you prefer, you can use a common mouse, or to facilitate transport, mini-mouse that uses a PS / 2 or USB, or Bluetooth wireless technology or WiFi.

9 - Ports

In any computer is essential to have USB ports. In notebooks, the minimum required are two ports (for connecting printers, digital cameras, MP3 players, mouse, etc). Some models also offer a PS / 2 port for connecting a mouse. It is also essential to have an Ethernet connector. A few models offer FireWire port and card reader. The FireWire is not used, therefore it is important to keep it only if you use an application that uses this port. Many of the notebooks have an infrared port for communication with other devices, however, and this resource tends to be more used not, as there are better alternatives, such as wireless networks (wireless) and Bluetooth connections. Having wireless resources is essential today (Intel's Centrino line is a very interesting option for these cases), but the Bluetooth is only important if you want to connect to other notebooks, PDAs or mobile phones. It is also interesting to have a dialup modem (phone line), for cases where you only have the option of internet access.

10 - Brand

The major computer manufacturers offer models of notebook quite interesting. These include: HP, IBM / Lenovo, Dell, Toshiba, Asus, Sony and LG. There are also lesser-known brands such as Acer and Powernote. Just as there are companies that assemble common PC, there are companies that assemble notebooks. These are the names and lesser known companies. It is often convenient to purchase equipment from these manufacturers, but the need for caution in the choice: check if the brand has a network of technical assistance, check if it provides support (by e-mail or phone), analyze the warranty period, not purchase notebooks that have a lower 1-year warranty, check whether the equipment of interest does not have an obsolete technology (passive matrix display, for example), ask on forums if the brand is reliable.
