Shopping Guide: 10 key points when buying a laptop

Shopping Guide: 10 key points when buying a laptop

We want a laptop . Our computer has become old or just feel like we have a new computer for other needs. are many questions we ask at this point. Especially with regard to what our needs. There are many computers on the market with very different prices. In this little guide we review a few tips to keep us out by buying the stock.

1. Fulfilling your needs

In the market there are computers that cost a fortune. We believe that we should always buy the best since it will soon be outdated, but this is not exactly true. It is true that over time we will need a more powerful computer, but some things that pay very expensive may not make us never lack.

The clearest example is the graphics card. This element helps the functioning of the computer when we are using some graphics functions. They come in all types and prices, not everyone needs the best. If we are not interested in video games or graphics editing programs do not need a graphics card at all expensive.

2. A PC or a Mac?

This question has many answers as users. Beyond the technical characteristics of a team, there are things that can not be measured as the degree of satisfaction in what they call "user experience". Many of the buyers of computers Apple say that they would never use a PC with Windows .

However, with the figures in hand, Windows PCs are much cheaper than the Mac. They are compatible with many more programs and what they're used to most users. If you have never used a computer in his life, probably more easily would drive a Mac, but if you bring with Windows life history change much.

Try both operating systems before making a decision. The mac s are in, but if your budget is tight, it can hardly get one. The cheapest laptop brand of apple costs $1,500 and has 11 inch screen, rather small. For that price you can buy two laptops with Windows similar technical characteristics, but with a much poorer design course.

3. Do I need a laptop?

Laptop computers already outsell desktops. They are more comfortable to transport, and not have to be fixed in any part of the house and the price is much higher. It may seem that buying a laptop is the most logical choice, but may not be so in certain circumstances.

A laptop is practically impossible to extend. If you need more RAM or a hard drive more internal capacity will be very complicated and expensive that we can install it. Also, if we spent many hours on the computer ends up being more uncomfortable.

Again, before approaching the store have to be clear about our needs. If we use computer to work for hours, cervical appreciate our convenient monitor to eye level, something impossible on a laptop.

4. The hard disk

One of the points that usually pay more attention, but again, the winning horse does not have to be the largest. Sometimes c Ontar with a hard drive on a laptop great price and raises the foam. We must bear in mind that we will give use.

The more files occupy on disk are the video and music. If we are to store lots of files of this type we may want to have a great record. If not, the investment may be useless. We must also bear in mind that there are external hard drives cheap, that can help us if we fill our the our team.

Today, between computers are more advanced fashion drives SSD . These reports are not strictly a hard drive, but they do the same. The SSD or solid memories are based on the same technology as a pen drive. No moving parts, so they are much faster and reliable. But of course, has a disadvantage in offering (currently) much less capacity and are much more expensive.

A team with SSDs can be very interesting if we tend to use other storage systems in addition to the internal hard drive. For example, if we have an external drive that we use frequently or a storage system in the cloud.

5. Processor

It is the most important part of a computer. The real brains of the outfit. However, the importance of comparing processors in the purchase is rather low for most users. To put it simply, practically all there for sale are great and far exceed the requirements of the average user.

You may want to sell us the most powerful processor in the market but, again, the most we do not need at all. Having the best processor is essential if we are going to ask our computer demanding tasks, but to surf the Internet or writing texts, we can make do with one more perfectly average.

6. The Weight

If we come to the conclusion that we need a laptop, there are still many options. A laptop is portable, but not all want to carry on their backs all day. Not the same take the computer room to room in a briefcase and put it across town. The weight and size matter much in this case, and there are different options.

If we are to carry around your computer everywhere you can opt for two alternatives, depending on our needs. If the use will be very slight (see post, write a short text or surf the Internet a little) perhaps the best choice is a netbook . These computers have a screen rather small, somewhat limited capabilities and a very low price. They were very popular a couple of years, but the tablets have eaten much of the market. Yet still very useful if we are not convinced a tablet as a solution.

If in addition to carry everything we need to hang on enough power, the other alternative is a ultrabook . These teams are very popular these days, and most brands have presented their models. They are complete computers with good technical but very thin and light. Also the battery life is usually quite large. But have a great disadvantage compared to the netbook. They are much more expensive. They tend to be around 800 or 900 euros, compared to 200 or 300 that can cost a netbook.

7. Screen

The size or screen resolution are important points in a computer. A large screen is more comfortable to work or surf, and of course, much more suitable for watching videos. Also when viewing movies or series and to read, it is important to have a good screen resolution.

The resolution is nothing more than the number of pixels in the screen. When we talk about resolution Full HD refers (if we are trying to cheat) to a resolution of 1920 pixels wide by 1020 high. This is almost always best to be found in the market, ignoring the monstrous resolutions of some Apple displays.

As for size, more land means more volume and weight equipment. Once again, we will assess our needs in this field. As for the resolution there is no doubt: the more the better.

8. The price

In the end, almost everything is about the same, how much want to spend?. In the market we find laptops from $ 300 to several thousand. Is important to understand and respect as want to spend that budget.

Vendors stores typically charge a commission on their sales. Despite the honesty that characterizes so many of them, their advice is not always the most appropriate. Review your needs and your pocket, and remember not to spend more than three years before it returns to the store to the other.

9. Ergonomics

Sometimes we let ourselves be conquered by good design and exceptional value, regardless of whether a computer is comfortable or not. We'll have to spend a lot of hours in front of him, the better a try.

The key points to consider are the keyboard, touchpad and ventilation. The keyboard is a very personal matter. You'll have to write it, and touch is very important. Try typing a few sentences before deciding. The touchpad is that little area for which glide your finger and move the cursor. Those who are too young or left to bring them around can be a nightmare with time.

As for ventilation, much depends on what position you use your laptop. A lot of people like to place it on your lap. In this case, make sure the vent is located on the side. If you are in the bottom the equipment is not properly refrigerated, and can get away with his pants on fire.

10. Compare prices

There are hundreds of electronics stores, small retailers, supermarkets and many can be purchased online. The price differences between similar equipment are enormous if we stop to compare prices.

Before buying a laptop go to several stores, record prices and find other stores on the Internet. You can save money if you invest a little time in this process.

How to detect if your computer is infected with the virus Flame (and how to remove)

How to detect if your computer is infected with the virus Flame (and how to remove)

Flame is one of the virus that has struck the last week, is said to be spyware ¨ complex ¨ discovered to date is said to have been developed by the U.S. government to spy on other countries. Kaspersky it discovered two weeks ago but assume that is operational for five years.

This virus weighs 20mb! And is very comprehensive so much so that not only steals your passwords, can be transmitted over the network or USB, takes screenshots of the infected computer, audio gaba if it detects that the computer has a microphone, records the keys you press, spy on your network traffic (sniffer) may have access to nearby phones via Bluetooth, to fool Windows to infiltrate a system update.

The virus that was discovered almost by accident when the International Telecommunications Union (a UN body) hired to investigate a Kaspersky virus called Wiper, while looking for the virus Kaspersky ran into Flame.

The virus has infected computers in Iran, Syria and some in America. But if you want to be sure you do not have the virus then you could use a tool BitDefender is free and available for Windows computers 32 and 64 bit .

After downloading the tool, you pass the program to check all your computer by the virus, in the end if you find you have the option of deleting it.

Microsoft has also released a patch to fix the problem with the update but not sure this is quite difficult to repair.

Technological sounds of the past to remember in a web

Technological sounds of the past to remember in a web

There are many sound technology that accompanied us in the past , such as the Nokia ringtone, the sound of the old TV when the signal is going or when you connected to internet !

Well, now thanks to Brendan Chilcutt going to be able to remember as it has created a website simple with these sounds, for now only has 15 sounds, but says it will gradually add more.

If site is called Museum of Endangered Sounds and is online since January this year. He plans to collect sounds for 3 years and thereafter will be uploading them to your website.

Great idea Bredan Chilcutt and I would like to raise the sound made ​​by Capcom at the beginning of Street Fighter II.

What sound would like to add in your site?

Museum of Endangered Sounds

Nvidia introduces its new beast: the GTX 690

Nvidia introduces its new beast: the GTX 690

Nvidia has announced a new model to its range of graphics cards, which he defined as the fastest graphics card market.

Everything is focused on the Nvidia Game Festival that was held in Shanghai, and it was there where the green giant's CEO, Jen-Hsun Huang, he unveiled a new at the company to offer. The GeForce GTX 690 is the ultimate expression of the Kepler architecture, with two graphics processors GK104 integrados.Cuyas technical specifications, and officers are as follows:


    Graphics Card: GeForce GTX 690 4GB

    Graphics processing clusters: 8

    Multiprocessor aired: 16

    CUDA Cores: 3072

    Texture units: 256

    ROP Units: 64

    Graphics Clock: 915 MHz

    Memory Clock (data rate): 6008 MHz

    Total Video Memory: 4096 MB GDDR5

    Memory Interface: 512-bit

    Memory bandwidth, total: 192 GB / s per GPU

    The manufacturing process: 28 nm

    Total number of transistors: 7 million

    Connectors: 3 x Dual-Link DVI, 1 x Mini-DisplayPort 1.2

    Form: Double slot

    Power Connectors: 2 x 8-pin PCI-E Power

    Recommended Power: 600 watts

    Thermal Design Power (TDP) 300 watts

As regards its construction, has a chrome aluminum housing which ensures a better cooling Nvidia against the plastic which is commonly used in the market. In addition also gives more strength and durability. Also stresses its v entilador magnesium alloy for better heat dissipation, greater durability and less noise generation. In this connection is also maintained double chamber system to facilitate the dissipation and temperature control.

The new GTX 690 will be available in limited quantities from the May 3, but its full availability begins May 7. As many of you have probably already deduced as shown by this board, not cheap. The selling price to the public is $ 999.

With this, Nvidia gives another twist to the world of graphics cards, throwing around a monster that has a really great painting, but obviously will not be a bestseller because of its unique price. The GeForce GTX 680 is a unique card in his own right, but when it comes to taking things to the end, what better to put two GPUs on one PCB? Ladies and gentlemen, this is the GeForce GTX 690.

So we find more potenete card, failing to know the specifications of the new AMD 7990 but gives us the feeling that they will not take the throne of this new model.

The new processors from Intel Ivy Bridge, all that you need to know

The new processors from Intel Ivy Bridge

Intel today introduced its new processors Ivy Bridge. They represent the third generation of Intel Core chips. This time they are manufactured with the new technology of transistors 22 nanometers (nm), which means that the width of a human hair holds more than 4,000 chips. Thanks to technological change, the company manages to increase performance by 20 percent while consumption is reduced by a fifth over the previous generation chips. This 22nm microprocessor technology works with 3-D transistors Tri-Gate.

The above were 2-D (planar type) while the new have a 3-D structure, which adds a kind of small silica vertical fins to reduce energy leakage. This design provides high energy efficiency but also provides the performance characteristic of high-end processors. The initial release includes thirteen quad-core processors, for most desktops. Instead, the new dual-core processors, low power netbook computers aimed at will not be available until later this spring.

Computer manufacturers are very hopeful with the release of the new Intel Ivy Bridge, waiting to trigger equipment sales. In fact, one of the company responsible for the comment just the BBC that there are more than 300 mobile and portable products in development with their new processors, and more than 270 desktop computers, many of them all-in-one. The company has set up three manufacturing plants for new chips , and a fourth will go into production over the year. With that Intel intends to increase by 50 percent the supply of processors over the previous generation.

The Ivy Bridge have several developments. First, are the graphics performance improvements, which are greater in those configurations that use a GPU (Graphics Processing Unit) integrated, rather than a separate graphics card. This will facilitate the manufacture of equipment capable of working with 4K resolution video (like most advanced camcorders on the market) and to handle high-definition video calls. Of those graphics performance improvements also will benefit all users who want to recode videos to pass to a tablet or a smartphone or send e-mail.

Another advantage is the compatibility with USB 3.0 included, which will reduce production costs for manufacturers. So, will serve to extend the dissemination of that port high-speed hard drives, cameras and other peripherals. Among the new features of Ivy Bridge processors include several video-related technologies, including Intel Wireless Display (WiDi) that can display videos from laptop on the TV screen wirelessly with multichannel sound and full HD quality. For its part, Intel Clear Video HD Technology helps play Blu-ray movies and streaming videos from the web in HD 1080p.

4 tips to speed up your computer boot, Pc, Mac, Netbook, etc

4 tips to speed up computer boot

In recent times have begun to emerge called ultrabooks powerful laptops. One of the most attractive of these teams is the inclusion of an SSD as a storage system. These cards allow the laptop to turn very quickly (the difference with the hard drive is just remarkable). However, for other cases the system optimization is a vital point to avoid having to wait more time on the computer. I counted four interesting tips to improve boot speed computer.

TuneUp Utilities , a tool quite used to improve performance, has developed four basic tips to increase the speed of the computer to boot time. First, a council trite but that is really vital in improving startup times is in disable programs that start with the system and are not really necessary. One option is to use the built-in TuneUp Utilities. We recommend you take hold of solute , a program that stands out for its clarity and simplicity. Solute is studied with the time that "steals" each application or process that opens the boot, and offers the option to stop or postpone its operation until the computer is started and we are not performing any task that consume resources.

The second piece of advice offered is off the computer devices that do not use regularly, such as Bluetooth or webcam. These devices consume resources when starting the system and can slow the process. To perform this glitch you must go to Windows Device Manager. You can find the Device Manager in Control Panel (in Windows 7 Control Panel, Hardware and Sound, then Device Manager). It is recommended to disable those components that have no clear its utility in the system. To stop a device, click in the button on it and then on the option "disable". By the time we need to use it again follow the same path and "enable".

Third, we suggest increasing the RAM on your computer. Component is a pretty cheap compared to the processor and can make a noticeable difference when you start the PC. The last piece of advice offered is to change the configuration BIOS (the BIOS is the software that controls the basic settings of the computer). The computers have different ways of accessing the BIOS during boot. In many cases accessed by pressing the delete key when the computer is booting (before it loads the system). From this platform we can determine that the boot is made ​​only from the hard drive, leaving out the optical drive or USB. Thus, it may save a few seconds. Anyway, we only recommend performing this advice if you are familiar with the operation of the BIOS.

Remove test programs (and other junk) from New Laptops and PCs with SlimComputer

Remove test programs (and other junk) from New Laptops and PCs with SlimComputer.

You just bought a laptop or a PC ? Congratulations! However, one of the early headaches we find, after setting  at home, is the number of " programs garbage "that are installed.

From antivirus that lasts a week, trial versions of Office, a lot of applications that never will use, all you get these programs to us users, is to remove large percentage of computer performance that we should be providing.

This is because many of the manufacturers of laptops / PCs generate deals with software developers to include such programs (is a good hook for users to buy applications, after the trial period). The problem is that. probably will not use much of it. 

Meet, then, SlimComputer, an application that takes care of cleaning all this trash with a few clicks. We have seen a similar application in the past ( PC Decrapifier ) per or SlimComputer offers a cleaner interface, regular updates, a community that is responsible for defining which programs should be marked as junk, and more.

Before deleting it all, we have the option to review the list of programs, toolbars and other applications to uninstall, if we want to leave some. Another important aspect is that each application has a rating given by the community to know how bad or good the program. For example, you probably will want to leave some brand-specific programs (in the photo, Sony Vaio software, for example), but for other things like trial versions of Norton or McAffee, the best we can do is remove .

And along with the elimination of these applications, we also have an optimizer, which is nothing more than a tool that takes care not to allow unnecessary programs from starting, which helps speed the loading time of Windows .

Definitely SlimComputer has become my new recommendation when you delete files from a laptop or new PC, it is a much more comprehensive than PC Decrapifier .

Como recuperar el contenido de un archivo ZIP dañado

Como recuperar el contenido de un archivo ZIP dañado.

Es prácticamente inevitable toparse en algún momento con un archivo zip dañado. La causa más común en estos días es una descarga incompleta, pero un medio de almacenamiento defectuoso o incluso problemas de estabilidad en un ordenador pueden dar como resultado un archivo zip cuyo contenido no se puede descomprimir. Lamentablemente, la corrupción no puede ser reparada, pero lo que sí puedes hacer es recuperar aquellos archivos dentro del zip que no se han visto afectados. Para ello existe una herramienta muy sencilla llamada Zip2Fix.

En aquellas épocas en las que debíamos tratar con extrema delicadeza a los discos flexibles, los archivos zip corruptos eran algo bastante común. La razón era sencilla: Algún sector en un disco demasiado lleno solicitaba un retiro anticipado, y la información que se encontraba allí simplemente se desvanecía en el aire. Teniendo en cuenta el costo de los discos flexibles en aquel entonces, utilizábamos hasta el último byte disponible, por lo que esa antigua herramienta conocida como PKZIP era una bendición. Los medios de almacenamiento se volvieron mucho más estables, pero la corrupción en archivos zip sigue apareciendo de forma esporádica. Un servidor que cerró la conexión antes de tiempo, un pendrive con problemas, un disco duro que está en las últimas o un CD-ROM convertido en una pista de patinaje son algunas de las posibles causas.

La interfaz apenas supera su rol de método de notificación, con un par de botones disponibles

A menos que el creador original haya tenido la precaución de agregar información de recuperación en caso de daño (algo en extremo raro), la corrupción en un archivo zip no puede repararse. Sin embargo, lo que sí puedes hacer es realizar una extracción forzada para recuperar aquellos archivos que no fueron alterados. Algunos de los compresores más comunes permiten esta extracción selectiva, pero Zip2Fix es una sencilla herramienta que tomará los archivos intactos en el interior del zip, dejará de lado al componente corrupto, y como resultado crerá un nuevo archivo zip con la corrupción “extirpada”. Luego podrás extraer los archivos con la herramienta de tu preferencia.

El contenido recuperado irá a un zip nuevo

A pesar de encontrarse en una etapa temprana de desarrollo, el funcionamiento de Zip2Fix es tan lineal que no hemos tenido problemas durante nuestras pruebas. Existe la posibilidad de que algún archivo zip comprimido utilizando un algoritmo inusual (como por ejemplo, los que ofrece 7-Zip como alternativos) sea demasiado para Zip2Fix, pero el formato zip siempre ha sido reconocido por su alta compatibilidad. Zip2Fix no puede evitar la pérdida de datos en un archivo zip, pero al menos puede minimizarla, y su beneficio es directamente proporcional a la cantidad de archivos que hayan sido comprimidos en el zip afectado. Zip2Fix no requiere instalación, y es un buen candidato para cualquier pendrive de emergencia.
