Laptop Buying Guide - Which Laptop Should I Buy?
You may have spent a fortune on that brand new laptop. But technology is evolving at a fast pace, and your laptop will invariably feel old in a couple of years. It is, therefore, imperative that you buy a model you will be comfortable with for as long as you want to keep it.
Basic Laptops
Before buying a notebook make a realistic assessment of your requirements. Are you a compulsive gamer? Do you tend to watch lots of HD video on your computer? Most users have pretty limited needs that extend only to web surfing and word processing. Any laptop available in the market can meet these requirements. So there is no need to spend thousands of dollars on a high end machine. Besides cost, the other factors that need to be considered are portability and usability.
Do you travel a lot? Mobile professionals need a thin and light machine they can carry around. Netbooks are a good choice for them. These machines are incredibly popular now. They are ultraportable with 9 or 10 inch screens. Another reason behind the popularity of netbooks is their price. These are cheap computers. But buying a netbook isn't a very bright idea if the machine is intended to be your primary computer. Compared to mainstream laptops, netbooks have much less powerful hardware. And the small screen size may strain your eyes if you use it for extended periods.
Upgrading
Upgrading a laptop isn't totally impossible, but it isn't very easy either. All laptops have some parts that cannot be replaced at all because they are soldered to the motherboard. Chief among the components that can't usually be replaced are CPU and Graphics cards. There are of course some parts that can be replaced and they include hard drive and RAM.
Laptop Components
Laptop components are mini versions of their desktop counterparts. They are pricier than desktop components, but they aren't necessarily more powerful. In fact, laptops tend to be less powerful than desktops. This is because laptop components usually run at slower speeds so as to reduce heat build-up inside the chassis.
Processor/CPU
The processor/CPU inside a computer has the greatest impact on system speeds. Intel and AMD are currently the leading CPU manufacturers. There are other chip-makers too, but they usually cater to the lower-end of the spectrum. Intel processors deliver slightly better performance than AMD processors, but they are also pricier than their AMD counterparts.
Graphics Card/GPU
The graphics card/GPU is an integral part of a gaming laptop. If you are not an avid gamer, then you don't have to buy a laptop with a discrete GPU. But remember that having a GPU will be helpful while running photo and video editing applications and playing HD video. If you tend to play a lot of games, you should buy a laptop with a discrete ATI or NVIDIA graphics. Intel processors usually come with an integrated graphics solution such as the GMA950 or 4500MHD, but these are practically useless for playing graphics rich modern games.
RAM (Memory)
RAM stands for Random Access Memory. Having sufficient RAM is extremely essential for getting good performance from your laptop. For instance, you will not be able to run multiple applications simultaneously if you do not have enough RAM. So how much RAM is necessary? Well, it depends upon your exact needs. Most netbooks come with 1GB of RAM. Higher-end models will usually have 3GB or 4GB of RAM. Laptops with 8GB and 16GB of RAM are also available at the moment. 1GB of RAM is usually sufficient if you are an average user.
Storage
How much storage space you need depends upon how you use the computer. If you only store spreadsheets and your office documents, you will not need much space. But if you use your laptop to store movies, music and photos you will need to buy a model with a large hard drive. Basic laptops usually come with 80GB or 160GB hard drives. Pricier models with 500GB or 640GB of hard drives are also available.

Laptop or Tower
When asking the question which is better to buy a tower/workstation or a laptop the question used to come down to the size of your wallet. For a long time PC towers were simply cheaper than a laptop to buy. Normally half the price for the same specifications.
This is now no longer the case as the price of a laptop is now comparable to that of a tower. So now cost is no longer the main issue lets consider the advantages/disadvantages each type of system has.
In the case of the laptop the first most obvious advantage its portability. Designed not only to be easily chucked into a bag and carried to where-ever to want to work or play, but also by having its own internal power source it means you not limited to one place. With the advent of wireless broadband your not even limited by needing a fixed line connection any more. You can take it camping, work in bed, take it to the office, anywhere. However this size and portability is also a limiting factor. Most display screens on laptops are around 15 inches, some go up to 17 in. but anymore than this and the laptop loses its advantage in portability. Laptops also lack space for large internal fans or other mechanisms to cool of the main CPU. Some manufacturers have tried to overcome this limitation by inventing the dual core CPU (a bit like having two carburetors in a car), soon no doubt we will seen quad core and more. Hence laptops CPU's are more likely to experience failure due to over heating.
Towers on the other hand are fixed to a single workplace unless you get some sick joy out of lugging wires and equipment from one place to another and figuring out where every connection goes. This fixed location though does have some advantages, your display screen can be the size you want. You can add great extras like a 6 speaker sound system with sub-woofer so loud that when you play your latest shooter game, your neighbors ring the police thinking the sounds of gunshots coming from you house are real! In fact a workstation can be adapted into a full one stop office and multimedia center with a joint printer/fax/copier scanner, a digital camera, music player, DVD theater system, etc.
Another advantage of a tower over a laptop is the ease of upgrading. With a laptop the equipment is so tightly squeezed together that only an expert repairer dare enter the system and there certainly isn't room to add in more stuff. Whereas with a tower even most novices can learn how to plug a new graphics card, or replace a hard drive, increase the memory by inserting another card. Open most towers and you will see lots of space for all sorts of additional equipment Plenty of space to collect dust too, so don't forget to gently vacuum and clean it now and again - circuit boards, chips, etc don't like dust.
I hope this article has helped you with your next computer purchase decision. Of course if your wallet is big enough you can buy both!

The Cheapest Gaming Laptop
Finding cheap gaming laptops has not always been easy, as games traditionally require a lot more functions and resources from a computer than traditional uses such as emails and word processing. However, if you are an avid gaming fan then there are ways you can save money on getting a laptop, enabling you to play your favorite games on the move.
When buying any gaming laptop there are a number of specifications you have to look out for. The first is your processor - don't skimp on this, and it will be required to run the top games. For some idea of what the power should be, check out the specifications provided by your games manufacturer. You should also get a laptop with a good amount of RAM. Try going for at least 2GB. The good news is that RAM is getting cheaper all the time.
Another essential element to the gaming laptop you choose will be the video card. All modern games will require that you have a video card. Laptops usually come with them, but many aren't suitable for playing the newest games. This is why you should check your game specifications carefully to make sure that you won't be disappointed when you end up buying your new laptop.
There are many places you can look for the cheapest gaming laptop. Try retail stores, but remember that the internet is often cheaper. Simply browsing with certain specifications in mind can come up with great deals, but gaming laptops are always going to be more expensive than standard machines.

External Laptop Batteries
External laptop batteries provide the user with almost seven hours of uninterrupted power. This is a major breakthrough in this field because laptop users had to depend on normal batteries that only worked for two hours. The most important advantage that an external laptop battery offers is that the user does not have to connect his laptop to a power source every couple of hours in order to recharge the conventional battery. Therefore, an external laptop battery is the best solution.
External laptop batteries are very cheap and can be charged by an external battery charger. A laptop user can make a decision about the chemical that is used for manufacturing these batteries such as Nickel Cadmium or NiCd, Nickel metal hydride or NiMH, Lithium ion or Li-ion batteries.
The price of an external battery may vary from $120 to $200 and these batteries are available on the Internet as well as in the regular market. As computers and other related appliances are becoming cheaper, the prices of laptops are also dropping. This means that more and more people are using laptop and for longer periods. These batteries are ideal for those who want an extended power source for their laptops when they are traveling. An external laptop battery connects to a laptop through an AC adapter plug and usually have two output levels. It consists of an adapter, a chord and thirteen other connectors. Another advantage that these batteries provide is that they are universal in nature. This means that an external power battery that is manufactured by a particular company can be used with a laptop of another make and model.
External laptop batteries are revolutionizing the IT world by providing more mobility and extended power for those who want to use the laptop for more than two hours without worrying about power interruptions.
