Notebooks And Netbooks

The ability to move freely and independently by not having to leave home or office our documents, is a very important factor.

This is why today the notebook or laptop is a very useful and helpful.

A personal computer with a display, keyboard and battery power, all integrated in the same frame and characterized by reduced size and weight to allow for easy transport andmobile use.

The term netbook or ultraportable laptops are some details of the average size of a notebook and subnotebook intended primarily for surfing the Internet and word processing and designed especially for non-professional audiences.

Characteristics of Notebook Screen Display

One of the most important of notebook is the screen display. Especially for the portable office, which are used for 8-10 hours a day, should have an excellent display.

Basically, the displays are divided into displays with reflecting surface (glare type) and displays with non-reflective matt surface (non-glare type). The anti-mirror is made with a special surface treatment of the display, which reduces annoying reflections. Some manufacturers (Sony) apply a special coating to eliminate screen glare.

In addition to individual preferences should also consider the following experiences when deciding between a reflective screen or opaque:

1. The reflective displays are better for color representation.
2. The opaque displays require a brightness of at least 150cd / m² to provide a good image and be suitable for use in open environments.
3. The reflective displays can hardly be used outdoors. The reflections in bright environments impede the work with these types of screens.
4. Annoying reflections can also occur in closed environments (ie if a light source is behind the user)
5. the displays with reflecting surface will eyestrain more than displays with matte finish.

On the one hand, the size and resolution of the display are related to the size of the laptop, the other depends on the type of use that the user intends to make portable models available.

There are widescreen displays and standard displays. The abbreviations (VGA, XGA, WXGA ,...) indicate the display format and resolution.

Usually, the reaction time of the display is indicated by the manufacturer. This can range up to 60ms (milliseconds) for displays with high stability of viewing angles. This value is fine for portable office and does not disturb.

Too long a reaction time can be problematic with multimedia applications and games with the (shooter), can appear as lines. This phenomenon can be observed while moving the mouse or the scroll is made.

Stability of viewing angles is especially important for mobile handsets, as it is not possible to maintain an optimal position. Therefore, a wide viewing angle vertically and horizontally is an advantage that ensures maximum mobility in combination with the best image quality.

Excessive deviations from the cone of vision can create problems of representation, darkening or bright light, color or deo fake reflections.

A very important aspect discussed is about the TFT displays error pixels. There are several types of errors, which differ in color. A permanent error white or black in the center of the display can be really annoying.
Almost all TFT displays are part of the class 2 pixel errors. This means that there is a default tolerance for error pixels. 

Some manufacturers offer a guarantee zero-pixel-error, while others enter a tolerance of errors in the warranty conditions. If you want to be sure that your laptop does not have errors, you should consult your display on site or make use of the right of withdrawal provided for by law. A further possibility is to establish an agreement with the dealer.

However, it is possible that errors occur in days, months or years.

Most Common Causes Of Damage Notebook

Most Common Causes Of Damage Notebook - During the survey, 72% of respondents reported damaged notebook to have suffered damage to the keyboard, while 66% have suffered failures of the screen. Components are not exposed to suffer more damage include batteries and hard disk drives, both mentioned by more than 50% of respondents.

Human error and lack of attention are responsible for much of the damage, with 72% of respondents claiming to have dropped the laptop, 66% had liquid spilled on the device and 55% claiming to have done dropped from the desk or table. The departments that have suffered most damage are those of customer service, followed by the administration and sales.

Issues linked to damaged and broken laptops
According to the poll conducted by IDC, 63% of respondents reported a decline in production as a result of damage or breakage of the laptop, and has listed more than one third loss of data or relevant business information (37%) and delayed or lost sales(34%).

In parallel to the perspective provided by IDC in the UK, an increase in sales of laptops in 2010 compared to desktop computers, the analyst group has advised companies to choose more carefully the type of laptop that you intend to buy. "IDC says that new strategies for the purchase of laptop should include specific metrics that concerns the quality of the product with an eye to durability," said David Daoud. "Businesses should obtain the notebooks specially designed to withstand different situations, not only to dust, dirt and extreme temperatures, but also strokes and sketches. They should also obtain a notebook in which key components such as keyboards and screens are reinforced, ensuring that the internal parts are of durable quality. "

"The use of laptops has become ubiquitous in the enterprise with a growing number of departments that benefit from the flexibility and convenience offered but that put a little attention to the type of product purchased and the impact of the" total cost of ownership"about," said Stephen Yeo, Marketing Director EMEA Panasonic Toughbook."Companies should consider whether a ruggedized laptop is right for its staff because in many cases the high initial investment is quickly repaid by the long life expectancy of products and cost savings from the ordinary."

Guide Of Video Cards For Notebooks

ATI, Nvidia or Intel? Explanations and tests for orientation in the choice of graphics card for notebooks that best suits your needs.

Video cards are one of the parameters that affect more the performance of a notebook, in some cases reserving unwelcome surprises: this is due to the fact that the performance difference between video cards less powerful and the most high can be as high as 10 times as much.

This does not mean that you should always choose the best performance: the best choice for a graphics card in a notebook is the one that best adapts to the needs of end-use.

The video cards in notebooks dedicated to the consumer world (thus excluding professional video cards) are divided into 2 categories:

1. Integrated (Intel GMA)
2. Dedicated (NVIDIA GeForce - ATI Mobility Radeon)

The integrated video cards (otherwise known as IGP - Integrated Graphics Processor) are less powerful chips that process video streams using the system memory. They are very popular especially on notebook systems with the Intel Graphics Media Accelerator solutions (GMA) combined with Intel processors.

PRO: solutions to manage personal productivity (office and Internet) and multimedia (for viewing videos in HD models in the past) without problems, ensuring very low power consumption that is not incommensurable with the mobility needs of ultra-portable notebook.
CONS: not able to manage complex video applications such as games or CAD programs.


Discrete graphics cards (or discrete) models are made by Nvidia GeForce and ATI Mobility Radeon that have GPU (Graphic Processing Unit) at frequencies too high combined with dedicated memory is often much faster than system memory. There are several models that provide very different services.

PRO: solutions generally able to manage, depending on the model, with more or less easy games and graphics programs, in addition to standard applications and high-definition video streams.
CONS: more expensive solutions, and more greedy in terms of consumption, which in fact reduce the autonomy of the notebook on which are mounted.


The performance of graphics cards are very different from each other and also vary depending on the games and applications: a good standard of comparison for the performance of laptop video cards is the benchmark 3D Mark 2006, that proposed by Futuremark in 2006, is still the gold standard for the performance of video cards:

The results shown in table comparing video cards notebook are average values ​​registered users and online presence in the various tests, the laptop and also very different configurations. Scores can vary greatly depending on your operating system, processor coupled to the video card, and depending on the version of the video driver. It should also be taken into account that some video cards are on the market in configurations that provide different frequencies and different types of GPU and memory.
