More than meets the eye.

Laptop batteries are the most important battery in the field of rechargeable batteries, but they are also the most complicated and regulated of all rechargeable batteries. The process alone to manufacture a laptop battery is long. How laptop batteries interact with the computer to function properly is another lengthy process. Manufacturers are also working constantly to improve laptop battery technology.

If you are the owner of a laptop computer, you know how frustrating it can be when you are working on the laptop and your battery is low. If you are constantly on the go, it is sometimes difficult to find a place to plug in your computer to let it recharge. There are a few things that you can do to help you take care and extend the life of your laptop battery.

Laptop computers are the perfect choice for people on the go. They offer all of the features of a desktop personal computer with the added benefits of portability. There are many kinds of laptop computers to choose from. When choosing a new laptop computer, look at the battery size, the memory and the physical size and weight of the computer.

Laptop or notebook computer is a small portable computer. It is light enough to hold on your lap. Laptops can easily perform all tasks that desktops do. Buying laptop is not an easy task to do because there are so many important things that should be kept in mind. Most common things are type of processor, speed of processor, amount of RAM, size of hard disk, brand and support.

You can easily move with your laptop from one place to another due to its portability factor. So check it carefully at the time of buying and if you don’t require portability you can prefer a desktop instead of laptop. Laptops are sophisticated and the perfect device for several business applications like record keeping, wireless networking, presentations and instant communication.

Laptop technology is changing day-by-day thats why it is not an easy job to find the best. These are smaller and faster than the desktop computers. Some high-quality notebooks come with Wireless Fidelity and many with tri-mode 802.11a/b/g wireless system. You can also choose Sony’s latest ultra-portable VAIO VGN-T350P that offers world’s first built-in cellular modem. It can be easily connected to Internet by cell phone.

Business laptops can be easily carried in a briefcase so while purchasing a new one keep in mind that its weight shouldn’t cause you any discomfort because sometimes you’ve to carry it whole day. You can choose lightweight and small laptop in the category of ‘Thin and Light’ and ‘Ultra-portable’. Laptops cost a lot and you can easily buy two desktops at the price of one laptop but keep in mind that you can’t take your desktop all day long.

Some laptops offer a storage space of 60 to 100 GIGS hard drives but you can increase the space with an external hard drive. Laptops are very powerful and can do each and every difficult job but generally you need 256 MB RAM for Windows XP and Mac OS X. you should also check its battery life at the time of purchase because it is an important factor for a traveling businessman. Latest models of notebook computers offer 5 or more hours of power but while choosing laptop battery you should always select a battery with higher numbered cells. Keep in mind that more cells will provide extra longer battery life.

You should also check security feature of laptop. You can choose one of the IBM/Sonoma ThinkPad series that can easily protect your sensitive and confidential company records and documents. Last but not the least factor is price that is extremely important at the time of buying laptop. You can try two or more shops for a reasonable laptop. Buying laptop on Internet is another option for you. You should try to bargain for a special price. Several manufacturers offer cheap prices if you’re buying in bulk.

You shouldn’t sacrifice for the quality for a cheap price. Try to buy a laptop that can easily satisfy your all requirements. You should check speed, upgradeability, and serious gaming factors at the time of buying laptop.

If you are in the market for a cheap laptop, I am sure you will be asking yourself that question. As prices for laptops continue to fall every month, Laptops become cheaper yet more powerful and this is really good news for cheap laptop buyers. However if you have not been following computer technology, you can easily be swarmed by too much information. This guide aims to give you an idea what features you should look out for when you buy a cheap laptop that cost less than US$1000.

For many of us personal computers and laptops have an important role in work and life. We all know that, and apparently cruise lines know that too.

That is the reason why they put a lot of effort into facilities and services that will cover information technology needs of passengers.

For many people it is enough just to exchange few emails with their families or friends during vacation and they can do that from internet caf? located either on the ship or in the port.

Upgrading the memory in your computer or laptop is one of the easiest and most cost-effective ways of improving your computer’s performance. Still many computer owners shy away from any memory upgrade for a number of reasons: lack of knowledge, warranty issues, fear of ruining their computers, compatibility concerns, or just an innate feeling that the inside of their computer is just some alien territory they must never venture.

Like a lot of things in life, a computer memory upgrade seems more complicated than it actually is. Most of the apprehension comes from a lack of knowledge. Let’s face it, the average computer user may only have a vague idea about RAM, Motherboards, Graphics Cards and the like.

They know their computer works when they turn it on and that’s all that really matters to them. However, what most people don’t realize is that with a little investment of time and a few dollars, they can make their computer work better and faster. It’s an investment that will quickly pay for itself; not only will you save time when doing your daily computer chores, but the overall enjoyment of your computer or laptop will greatly increase.

It’s best to tackle this problem or task with some good information concerning all the factors involved in the upgrading of your computer’s memory. Let’s start with the basics and work from there.

Get Out Of Jail Free Card!

(*Shortcut! Don’t have the time or desire to read all the ‘ins and outs’ of a RAM or memory upgrade but still want to upgrade your system. Go to the author’s resource box below and click the link. It will take you to a page where you can find a Memory Advisor tool which can scan your system and tell you which memory upgrades are possible with your particular computer or laptop.)

First Step - Know Your RAM

RAM or random access memory. This is what the computer uses to run applications and data on your computer. You need it to run your computer’s OS operating system, your need it for handling graphics, files, web-browsing, e-mail and multi-tasking. RAM is vital to the operation of your computer. As a general rule, the higher the amount of RAM you have - the faster your computer will work or run.

To complicate things somewhat, there are many types of RAM. The type of RAM in your computer or laptop may depend on the year it was made.

From mid-2004 a lot of the computers have DDR2 (double data rate, second generation) SDRAM (Synchronous Dynamic RAM). Before that time many computers had DDR (double data rate, first generation) SDRAM. Most older systems use SDR (single data rate) SDRAM, fast page mode (FPM), or extended data out (EDO).

To complicate things even further, most of the types of RAM comes in different speeds!

DDR2 SDRAM - is a new standard that can boost conventional SDRAM memory up to speeds well over 200MHz and beyond. For example, the new IBM ThinkPad T43, thanks to the Sonoma Chipset or platform has 533MHz DDR 2 SDRAM.

This is much better than standard SDRAM which tops out around 150-166MHz and DDR SDRAM which starts at 200MHz and goes up to around 400MHz.

Keep in mind, DRAM means Dynamic Random Access Memory and SDRAM means Synchronous Dynamic RAM.

And to really confuse you, having a faster RAM speed does not (by itself) make your computer go faster, you must upgrade or increase the AMOUNT of RAM in your computer system to increase performance. Also keep in mind your computer was made to accept a specific memory speed and there’s no benefit from going beyond that limit.

It’s usually recommended that you get the fastest speeds for your system, this will permit for better compatibility and make it easier for future upgrades.

Second Step - Know Your Machine

Without a doubt, compatibility is the most important factor in buying a memory upgrade for your laptop or computer. It’s essential that any upgrade be compatible with your computer or machine, i.e. otherwise it just won’t work.

Therefore, you have to know the amount and kind of RAM you have in your computer or laptop. The best way to find this is to check your owner’s manual. It should tell you the type of RAM your system is using, it should also tell you the maximum amount of RAM your system can take.

Obviously, an easy way to make sure you don’t exceed the maximum memory on your computer, just subtract your current memory from the allowed limit listed in your system specifications. For instance, if your computer takes a maximum of 512MB of RAM and you have 256MB installed - then you can upgrade to an additional 256MB of RAM (512MB - 256MB = 256MB).

You should also be aware that DDR is not backward/forward-compatible, which means that if you’re upgrading a computer that doesn’t have DDR technology, it won’t take a DDR upgrade.

Likewise, DDR2 is not backward-compatible, which means if your system doesn’t have DDR2 technology, it won’t accept a DDR2 upgrade.

So check your system very carefully and see what kind of RAM it has and the maximum amount of RAM it will take. You must also check to see if your computer’s warranty will be null and void if you install the RAM yourself! Some manufacturers actually seal your computer case and you must have an authorized technician to install your RAM.

Third Step - How Much RAM Do You Need?

It’s generally agreed that you need at least 256MB for Windows XP and Mac OS X. You will only need 128MB for other operating systems in Windows or Mac. Most general office work and heavy multi-tasking may need 512MB of RAM. Gamers or Professional Graphic workers usually need the most RAM - up to 2GB or more of RAM.

Please note, installing a faster speed RAM (as noted earlier) will not increase the speed of your computer or laptop. The only way to increase the speed of your computer is to increase the AMOUNT of RAM you have in your system. Going from 256MB of RAM to 512MB of RAM will speed up your computer. Going to 2GB of RAM will make it go even faster. Benchmark testing has shown that you can get from 28% up to 43% increase in performance, depending on the amount of RAM increase.

However, there’s always a spoiler, other parts of your computer must be able to handle this increase. Your computer will only go as fast as your slowest link. In other words, you may have to upgrade other elements in your computer to receive the benefits of a memory upgrade. Make sure you check this factor first before your make your memory upgrade. Otherwise, you may just be wasting your time and money.

Another consideration is the Memory of your Video or Graphics Card in your system. The amount of VRAM is the major factor in your display’s resolution and color depth. A faster and more powerful upgrade in your Graphics Card will give you increased performance especially for handling graphics and videos, as in 3D Gaming.

Fourth Step - Ordering Your RAM

There are over 110,000 different memory upgrades you can choose from!

There are many places to order your RAM, from your local computer store to online sites. If you’re ordering online, one the most highly rated sites is Crucial.com - these people are memory experts and know their memory! They are a part of Micron, one of the largest DRAM makers in the world.

Perhaps, what’s more important, Crucial has very high consumer satisfaction ratings from other third party rating sites. This gives you an unbiased recommendation or indication that the service and product is top-notch. Even more important, they have the Crucial Memory Advisor? tool which will scan your computer system and tell you what memory upgrades are available. They also back up their products with a lifetime warranty.

Some other thing to keep in mind when ordering your RAM. Many desktop systems or computers use what’s called “non-parity” memory which means it does not need ECC (error correction code) or “parity” modules.

Registered, buffered, and unbuffered are other terms that will come up - they refer to how a certain memory module processes signals. Usually, most PC systems take unbuffered RAM and rely on the motherboard controller to help process memory. Registered RAM is used mostly in servers.

Fifth Step - Installing Your New Memory or RAM

If you order your RAM online, you will receive your RAM module in an anti-static bag, along with detailed instructions on how to install your RAM. On modern system boards, RAM is installed on SIMM or DIMM modules (SODIMM in notebooks).

One of the most important things to do when installing RAM or working with your Computer is to ‘Ground Yourself’ to make sure you don’t ‘Shock’ your computer with static electricity. You can take some simple precautions to prevent this from happening. If you have wrist straps designed to prevent shocks, you need to wear them.

If you don’t have wrist straps, here’s a simple way to ground yourself:

You should turn off your computer, monitor, plus all accessories (speakers, printer, scanner). Unplug your computer and any accessories. Then quickly touch an unpainted part of your computer case and keep your feet planted in one position while installing your RAM. If you walk around, repeat the process above before you touch any internal parts of your laptop or computer.

Open up the back of your computer or laptop. Depending on your model, you may need a screwdriver. If you have a laptop or notebook, the memory slots are sometimes located under the keyboards. Most times, it’s in the back of your laptop - check your manual for the location of your laptop’s memory.

Depending on your upgrade, you may have to replace your RAM module with the New one, in other cases, you will be adding any extra module or two. Follow the specific directions that come with your RAM upgrade - installing the RAM is only a matter of a Push and a snap! Your RAM upgrade will snap into their memory slots without too much difficulty.

Before you close the case, turn your computer or laptop on to see if your new RAM is installed. You will see it on the startup screens or you can easily check it by going into ‘My Computer’ under properties - if you’re using Windows.

Basically, this is how to do your own computer or laptop memory upgrade. There may be other elements or aspects you might want to check out before installing your new RAM but follow the guidelines above and the detailed instructions that come with your RAM module or modules and you should be OK.

If you have any trouble, click the link in the resource box below. They have extensive detailed guides that you can follow. If may be a good idea to check out these guides first, before you order your memory, to see the kind of procedure you will have to do to install your RAM. Realizing how simple this procedure is may relieve some of your initial fears concerning a memory upgrade for your system.

5 Tips for Buying a Laptop

Buying a laptop is a major investment decision. As such it is not one that you should make lightly. Below are 5 tips that will help prepare you for making the best and most well informed decision when buying a laptop.

Tip #1 Size Matters

Buying a laptop is a matter that requires some thought. Consider the size and weight of the laptop. How often will you be carrying your laptop? Your answer will help determine which size and weight will best suit your needs. If you will be carrying your laptop frequently, a lighter model will be preferable.

The keyboard is another area to consider when buying a laptop. Why is the size of the keyboard important? A larger laptop will have a slightly larger keyboard area. But keep in mind that if you worry about your fingers or wrists taking on too much stress from typing on a keyboard that is too small, you may want this to be a main factor in your purchasing decision,

Tip #2 Choose Your Mouse

A laptop it will come with a built in touch pad, an alternative to the mouse, whereby the pad is controlled by the user’s finger movement. For some people, this type of pad is uncomfortable and not easy to work with. Before purchasing a laptop, determine what mouse options are available. Test each one and determine which one best meets your needs.

Tip #3 Wireless Options

Today, when many people think laptop, they think “wireless”. No doubt people want to make sure that their laptop computer will be able to access the Internet with a wireless connection. Many try to account for this by ensuring that their laptop has potential upgrade options, such as room for an expandable PC card or a USB port. However, since so many laptop users are looking for wireless connections, many of today’s laptops come pre-wired for wireless Internet. All you need to do is activate your wireless Internet service, and your laptop will take it from there. So depending on your needs, choose your laptop whether it is capable of expanding or if it is already configured for wireless Internet.

Tip #4 Check for Ports

Peripheral equipment will be connected to your laptop through USB ports. You will make your life much less complicated by ensuring that your laptop has adequate ports. Connecting equipment such as printers, scanners, and digital cameras will be much simpler if you have the ports readily available. If you are not sure, thoroughly read the specs for any laptop that you are considering purchasing.

Tip #5 Check Your Budget First

Finally, when buying a laptop, beware that you do not overspend. First create your budget and stick to it. When you think that you have found the laptop that you want, do not rush into it. Wait a day and check over your budget, requirements, and see if you are still as excited about the laptop in the morning, as you were when the sales clerk was showing off its specs. If you still feel that it is the laptop that you want to purchase, then go for it.

Make Your Laptop Wireless Enabled

Wireless technology or Wifi is probably the hottest technology in laptop computers today. Many people love the convenience of traveling with a laptop computer in order to do work and have access to files on the road, but until a couple of years ago, you weren’t able to access the internet unless you were connected by a cord.

Today Wifi technology has skyrocketed in popularity. No matter where you go you can find a Wifi Hot spot and pick up a signal in order to surf the internet. In order for your computer to be able to log onto the internet it must be wireless enabled. There are two ways for your laptop to achieve the ability to access the internet over a Wifi hotspot.

You can either have a laptop computer with Wifi technology built in or you can purchase a Wifi card. Most of today’s new mid level and upper level computers automatically come with Wifi enabled compatibility built into the computer. All you need to do is find a Wifi spot and log on. If your computer did not come with Wifi built in then all you need is a Wifi card. These cards are not that expensive and well worth it if you want to access the internet without a cord. So if you want to surf the internet no matter where you are, check out Wifi technology.

It is hard to go wrong with a used or refurbished laptop.

When buying a used or refurbished laptop make sure that it fits your needs. Create a list of the accessories and hardware that is you need. Most people are happy with a 700 Megahertz chip, others need at least 1 GHZ. Make sure that the laptop has ample storage such as a 20 GB hard drive or at least 256 MB ram. You might find that you can do with less but make sure that your computing tasks will be handled properly with the used or refurbished computers. If you want a CD player or DVD player make sure the laptop comes equipped with these accessories.

Depending on the type of used or refurbished laptop you are buying will determine the prices. You will probably be saving hundreds of dollars buying used. Many laptops can cost as little as $300. Whether buying on line or at a store make sure that there is a return policy or if you receive the product DOA they will fix it. It is always possible to have problems with vendors so make sure that you are clear on the terms of the sale. Most vendors are legitimate and most people do have an extremely good buying experience, but do your homework.
