How To Find Good Laptop Deals

Foreword By The Editor

The following article by Francua Smith is about making sure you manage to get the best possible deal for yourself when buying a new laptop computer. Like almost any other product, the best laptops are often available by means of some rather circuitous routes and some knowledge of various “tricks of the trade”. These are spelled out in this article. I hope you enjoy it and, if you do, finish by following the author’s links at the end of the article (About The Author).

Shopping

Whether we shop for bread and milk at the neighborhood grocery store,  for shirts, ties and shoes at a downtown department store or for cars or homes—we all want good deals. It’s no different with laptops. Most of us want excellent deals. This article helps you locate those special deals for laptops.

Empowerment

Many of us are willing to take time to cut out coupons, to settle into lines winding around the block at the crack of dawn to be among the lucky shoppers who will get to take advantage of a one-day sale, to drive across town to save twenty five cents on a box of cereal while spending a dollar on gas and to fill out countless rebate forms that will ultimately get us refunds that will barely cover the postage it took to mail them in.

Have you ever wondered why we do that? Why are we willing to go through so much trouble just to save some money, at times a few cents while at other time hundreds of dollars? Is it all about economics? I think that economics has something to do with it, of course, but the bigger and more motivating factor is quite a bit more psychological and much less obvious.

What I am talking about is empowerment. When we get to pay less for something that we know, or we think we know, is worth more we feel that we have legitimately beat the system, whatever we define the system to be. And beating the system, any system, is empowering. Now let’s look at some ways to find good laptop deals.

1. Build Your Own Laptop

When it comes to desktop computers, you can save money and gain that euphoric feeling of empowerment by finding sales offered by their manufacturers or retailers, by using discount coupons or rebates. There is yet another way of saving your hard earned money on a desktop computer and that is by actually building one yourself. And remember that there is nothing more empowering than a job well done. The same goes for laptops. You can actually build one yourself. Hunt for cheap components and you can build a decent machine that meets your needs. Learn more about custom built laptops later in this article.

2. Make Use of Manufacturer Sales

Unfortunately I need to fill you in on some bad news:  building your own laptop is not an option if you’re not tech savvy. Or maybe you only want something out-of-the-box and don’t have the time to construct one from scratch.

Well, you can still save cash on laptops by making the most of existing sales such as manufacturer sales, blow-out sales, clearance sales, after holiday sales and so on. You can find discount coupons in newspapers and on the Internet, and you can take advantage of rebate programs offered by manufacturers.

Much like the build-it-yourself option available for desktop computers, laptop computers have a unique savings option of their own and this is to take your set of needs, match them up to the list of specifications featured in the laptop you are considering and stick to the results.

3. Buy Only What You Need

Buy only that which you will actually use or else you will be throwing away good money. Do not get sucked into the latest hype and be brave enough to be out of vogue. There is absolutely no logical reason why you have to “keep up with the Jones’s”. Let me give you an example: if your current computer, whether a desktop or a laptop, has a 50 GB hard drive and you have not managed to fill it up even after three years of ownership, do not be tempted to buy a new laptop with a 20o or 400 GB hard drive just because your friend has one. That would be a complete and utter waste!

Conclusion

Good deals on laptops would be where you have taken advantage of a clearance sale, or one that accepts the discount coupon found in your local newspaper, or one that honors a rebate program or one that offers what you need, no more and no less. Any one of these would make for a fine deal while a mixture of several would make a excellent deal.

Tips On Dual Monitor Video Cards

Foreword By The Editor

The following article by Donna Jonston is all about choosing a suitable setup for installing dual monitors on your computer. As explained, it is a very simple process, provided you follow the correct procedure. Read her resource box (it’s the last paragraph, under the heading About The Author).

Introduction

When you’re getting ready to buy a twin monitor video card for your personal computer, there are a few things that you have got to consider to get the right dual monitor video card. These steps are listed below and they’re going to help to get the right video card for 2 monitors.

Types Of Monitors

The first thing that you wish to do is to work out what kinds of monitors you’re going to be using, i.e. one CRT and one digital, 2 digital monitors, or 2 analog monitors.

Choose Your Card

The second thing that you need to do is to select a dual monitor video card that’s going to fit the monitors that you are using. For example, if you’re going with two analog, or one CRT and one digital, then you need a twin monitor video card that has either two VGA connectors or one VGA and one DVI-I connector. The DVI is used to fasten a digital monitor and the other one is used for attaching the CRT.

If you’re using both digital monitors, you need to get a card which has two of the DVI-I connectors. This card is one that is very flexible and will let you use any mixture of all monitor kinds.

Research

Once you have worked out what kind of dual monitor video card you’ll need to have, take a look at the different ‘buyer guides’ so that you get an idea of the versions, pricing, and features of the available cards. Getting an idea of what you can expect from a dual monitor video card will help you know what you are getting into.

Comparison Shop

Although you may have an idea of how much you’re going to spend on the card, that doesn’t suggest that you’ve got to spend that much. If you look around on the Internet for different prices, probabilities are that you are going to find some pretty good deals on the cards, especially around vacation times. There are websites that will compare the costs for you on items that you would like to buy, and there are sites that boast about selling electronics for less. So look around and do not pay the first price that you find for your card. You may find that it is cheaper somewhere else and you’re going to be disappointed that you did not wait.

Summing Up

It is not awfully hard to go buying a twin monitor video card. All you have got to do is to figure out what kind of monitors you are going to be using and then buy the right card for it accordingly. If you take your time and look around, you may even find the card that you’re looking for at a lower price than you were expecting to pay. So take it slow and research, and then look round to find the most competitive price. Using the Internet to comparison shop is your best bet.

Effective Registry Cleaners

Foreword By The Editor

Registry cleaners can be extremely useful tools and should be used regularly, especially by those without a lot of experience in good computer management. This article by Susan Reynolds covers this topic well and clarifies some issues that are not always apparent to the computer illiterate.

Tools For The Job

The Registry Editor in Windows Vista

Registry-cleaning programs are getting more and more popular these days, and for good reason. They’re a crucial tool for repairing computers. As a computer repairman, I personally use a registry cleaner in four out of five house calls! There are a lot of different reasons for this, and I’ll tell you the major ones here.

Probably the topmost reason is that I know they enhance the system’s overall performance. Many computers have some errors during start-up or shut down. Not all of them necessarily show up as errors though.

Causes Of Common Errors

One of the most common reasons for these types of errors is uninstalled start-up programs. The computer expects it to be run on start-up but it doesn’t exist anymore. However, the registry still thinks it does and still calls for it. Sometimes it can just be as simple as a wrong file path. A nice easy scan with a registry cleaner will fix these kinds of problems without much trouble, and I usually wipe out those little things before I even start getting to any major problems with a computer.

More Tools

In many scenarios, registry cleaners do not just act just as registry cleaners but also contain many other tools in them. For instance, nearly all registry cleaners contain a missing or broken links verifier. It is a fact that missing links on the computer can increase the boot time, thereby making it sluggish, even though many people are not aware of it. Also in the event that you attempt to open a folder that contains broken link then the computer would be too slow in opening that folder.

This also applies to start-up managers. Although computer geeks would make use of ‘msconfig’, if you do not have a fair idea about it then it may cause great problems for you. Registry cleaners are expert at completing this process and most of them do not even show up the important Windows start-up files so that you do not commit a mistake.

Most registry cleaners also contain a junk file remover tool to remove all the sites, cookies, photos, pictures and many other types of data saved to your computer on different parts of the hard drive. Getting rid of such files would definitely enhance the speed of the computer and show a significant improvement in its performance. Even though Windows has a junk file cleaning tool internally built into it, it is not unfortunately very effective.

Summary

Take all those features into account and you’d be crazy not to have a decent registry-cleaning program on hand to run when you need it. It’s just so convenient, why would you ever want to be without it? It can save you a chunky repair bill, and a great deal of stress.

Five Laptop Upgrades You Can Do Yourself

Foreword By The Editor

Five laptop upgrades you can do yourself are covered in this excellent article by Francua Smith. Most people, even those who are basically familiar with the workings of their tower PC, do not realize how easy it is to keep a laptop in good order. If you are one of those, the following processes will probably help.

Tired Laptop Needs A Tune-Up?

Do you have an aged laptop which you feel is in need of an upgrade? Well, the possibilities for upgrading an existing laptop are, fortunately, quite good. From Bluetooth to wireless adapters, extra RAM to a fresh tough drive, there are many things you can do to upgrade your existing laptop. In this article we will lookat five laptop upgrades you can do very simply yourself, without taking the machine to the manufacturer.

Upgrade Number One

Increase the memory of your laptop. Now, dollar for dollar, increasing your system’s RAM is the most value for money upgrade you can perform. If your Windows Vista is chugging along with a lot of hard disk swapping and slowing down terribly, pump in another 2 GB of RAM and watch what happens. You’ll be amazed at the speed improvement. Head over to Crucial.com to check out some good laptop RAM deals.

Upgrade Number Two

Install a new hard drive. Another favorite improvement can be the laptop tough drive. I used to have a miserable 60 GB tough drive in one of my aged laptops and I can say to you now that in this day of enormous videos and MP3 music, 60 GB is not enough. Do yourself a favor and improve that tough drive to something like 160 GB. The other option is to get an external tough drive (say a 320 GB monster) and then you can forget about running out of tough drive space.

Upgrade Number Three

Arrange Bluetooth connectivity. Bluetooth technology is incorporated in some laptops but not others. For laptops without in-built Bluetooth, you can buy a USB dongle with Bluetooth capability from any good computer shop. This usually comes with some software which allows you to install Bluetooth capability into your laptop. Very important for those you like to synch their Bluetooth enabled mobile phones to their laptop.

Upgrade Number Four

Get a laptop stand. Ok, this is not precisely an upgrade, but I find laptop stands increasingly the favored improvement with the mobile computing crowd. Laptop stands are good for your posture and some of them also allow your laptop to cool better. It’s surely a fine ‘upgrade’ to assume, whether you leave your laptop at home a lot or not. Just plonk the laptop stand on the desk and you’ll be able to enjoy better computing without ruining your posture from then on.

Upgrade Number Five

Invest in an extra battery. If you’re on the road a lot, you should really consider buying an extra battery. In particular, if your laptop runs out of battery juice quickly, a second battery is almost a must. I bought an extra battery for my ThinkPad X61 and I can sit at a cafe typing away for 8 solid hours, without requiring a recharge. Heaven!

Conclusion

Well, now you know about five laptop upgrades you can easily perform yourself. The next time you feel your laptop needs a bit of a tune up, look to the above list and see what components you can upgrade. Sometimes a small upgrade (especially additional RAM) will do wonders for your laptop and overall computing experience. By the way, if you’re interested in learning more about the ins and outs of laptops, you may want to check out my laptop guide.

Studying For Microsoft MCSA Clarified (UK)

Foreword By The Editor

Studying for a Microsoft MCSA is a vital early step for those intending to pursue a career in IT Systems Administration nowadays. It is also a good idea for those already experienced in the area but who want to match their expertise with a formal certificate of recognition. This excellent article by Jason Kendall covers the subject from a UK perspective in a clear and comprehensive way and should be useful reading for anyone interested in this field.

MCSA Training And Courses

Front entrance to building 17 on the main camp...
Image via Wikipedia

If you are ready to get certified at the Microsoft Certified Systems Administrator level of study, amongst the finest methods available are based on CD and DVD ROMs using training that works interactively.  So if you are a professional but are about to formalise your skill set, or are just about to get started, you’ll discover technologically advanced MCSA courses to fit your requirements.

To qualify at the level of MCSA you need to pass four Microsoft Certified Professional (MCP) exams. If you’re joining the industry for the first time, the chances are you’ll need to have some coaching before tackling the these. Identify a training company that has a team of advisors who can identify the right way to tackle your goal and who will get you started in the right place.

Training Methods

We’d hazard a guess that you probably enjoy fairly practical work; in other words, you’re a ‘hands-on’ person. Usually, the unfortunate chore of reading reference guides is something you’ll make yourself do if you have to but you really wouldn’t enjoy it. So look for on-screen interactive learning packages if book-based learning really isn’t your style.

Studies in learning psychology have shown that we remember much more when we receive multi-sensorial input, and we take action to use what we’ve learned.

The latest audio-visual interactive programs involving demonstration and virtual labs beat books hands-down. And you’ll actually enjoy doing them. You’ll definitely want a look at some courseware examples from the school that you’re considering. The materials should incorporate expert-led demonstrations, slideshows and fully interactive skills-labs.

Avoid training that is purely online. Always choose CD or DVD based study materials where possible, so you can use them wherever and whenever you want. ISP quality varies, so you don’t want to be totally reliant on a good broadband connection all the time.

Consider Your Needs

Kick out a salesman that just tells you what course you should do without a decent chat to gain understanding of your current abilities and experience level. Always check they have access to a large stable of training programs so they’re able to give you an appropriate solution.

Of course, if you’ve had any relevant previous certification, then you will often be able to begin at a different level to a student who’s starting from scratch. Where this will be your first attempt at studying for an IT examination then you may want to start with a user-skills course first.

The Market For IT Skills

Let’s admit it: There really is no such thing as personal job security now; there’s only market or business security: a company will let anyone go when it meets their business interests.

Where there are growing skills shortages and escalating demand however, we always locate a newly emerging type of market security where, fuelled by conditions of continuous growth, organisations are struggling to hire the influx of staff needed.

The IT skills shortage around the UK is standing at approximately twenty six percent, as reported by a recent e-Skills analysis. This shows that for every four jobs existing around computing, we have only 3 certified professionals to fill that need.

Acquiring full commercial computer qualification is, as a result, a quick route to realise a long-term as well as gratifying line of work. We can’t imagine if a better time or market state of affairs could exist for getting certified in this swiftly expanding and budding industry.

Finding A Position

A service offered by some training providers is a programme of Job Placement assistance. This is designed to steer you into your first IT role. But don’t place too much emphasis on it. It isn’t unusual for training companies to overstate the need. The fact of the matter is, the huge shortage of staff in the United Kingdom is what will make you attractive to employers.

Help and assistance with preparing a CV and getting interviews is sometimes offered (alternatively, check out one of our sites for help). Ensure you bring your CV right up to date straight away. Don’t just wait until you’ve finished your exams!

Getting your CV considered is more than not being regarded at all. A surprising amount of junior positions are offered to trainees (sometimes when they’ve only just got going.) The top companies to help you find a job are most often specialised and independent recruitment consultants. As they will get paid by the employer when they’ve placed you, they’ll work that much harder to get a result.

Various people, apparently, invest a great deal of time on their training course (years sometimes), and then just stop instead of finding the right position. Market yourself. Make an effort to get yourself known. A job isn’t just going to bump into you.

Your Exciting Future

IT has become amongst the most electrifying and revolutionary industries you could be involved with. Being a member of a team working on breakthroughs in technology is to be a part of the massive changes that will impact the whole world for generations to come.

Society largely thinks that the technological revolution we have experienced is lowering its pace. Nothing could be further from the truth. There are huge changes to come, and the internet particularly will be the biggest thing to affect the way we live.

And don’t forget salaries either. The average salary throughout Britain for a typical IT worker is much greater than average salaries nationally. Odds are you’ll bring in a much better deal than you’d expect to earn doing other work.

The need for appropriately qualified IT professionals is assured for a good while yet, due to the continuous growth in IT dependency in commerce and the massive deficiency still present.

Ways To Extend Your Laptop’s Life

Foreword By The Editor

I think it’s fair to say that laptops and netbooks have now become an essential part of everyday life, at least in our affluent western society. This excellent article by Francua Smith highlights some of the best ways to get the most out of them.

Make It Last

You definitely want to try and make your laptop last as long as possible, whether to save having to buy a new machine every year or two or to get the best deal for it when you’re ready to change. If you want to extend your laptop’s life, there are some specific things you can do. No matter what it originally cost you, you’d do well to learn the following tips to extend its life.

Keep It Cool

NEW YORK - FEBRUARY 1:  Customers at the midto...

The first thing I always do to extend my laptop’s life? Well, it’s simple. Keep it cool. The more heat your laptop accumulates, the more likely it is to suffer from component failure. Note that, if you like to slump into a couch to type on your laptop, you will most likely block the machine’s air vents and prevent the air from circulating. This spells heat for the machine; which is not  a good thing at all. To cool a laptop, one good way is to get a cooling pad. These things draw heat away from the system and usually cost about $30. You will, at the same time, prevent your laptop’s internal fans from spinning unnecessarily, thereby saving your battery life as well.

Carry It Carefully

I’ve seen some folks treat and carry their laptop as if it’s a piece of junk. If you throw your laptop onto the bed and it lands on the floor, or you leave it in the hot sun on the back seat of your automobile… well, fine, and good luck! No laptop is going to survive long in those circumstances. You need to treat it with respect and carry it with care. As an extra precaution, get a bag that is specifically made to offer maximum protection. Targus is an excellent maker of laptop bags, many come complete with padded sidewalls with air-protection technology.

Choose An SSD

A solid-state drive (SSD) is a next generation kind of hard drive. There are no moving parts, no platters or read/write heads (hard drive jargon) and everything is stored in non-volatile flash memory, like in a pen drive. This does wonders for your laptop. You will have longer lifespan because you don’t have a moving hard drive that breaks down. It also generates less heat since there’s no hard drive whirring away in the background. Unfortunately, the prices of SSDs are still quite high and currently cost about $15 per GB of storage. These prices are, however, gradually coming down. I think the maximum size now is about 128 GB so they certainly have capacity. Remember to look out for them if you’re in the market for a new laptop.

Protect The Battery

Your laptop’s battery is really sensitive. Don’t charge and discharge it all the time. Whenever you plug your laptop into an outlet, make it a habit to unplug the battery. If you leave it in, the AC force could cause the battery to overheat and overcharge. Then, when running on battery power, utilize the laptop until you get a low-battery warning, then plug in the charger and let it recharge fully. That will extend the life of that battery.

Reformat The Hard Drive

If you find your laptop running really slow, one option is to reformat the hard drive. Remember, we all let all sorts of junk software clog up our operating systems but Windows tends to get bogged down by orphaned files, funny registry entries and spyware. Reformat the hard drive and install everything afresh (or get a friend or a shop to do it if you’re not sure how). I guarantee you will get your laptop functioning and running faster. One trick I like to use is to install all my essential software (Microsoft Office, Adobe Acrobat, etc.) then take a backup using imaging software (e.g. Acronis True Image). When you feel the laptop going sluggish, simply backup your data files and do an image restore. Your system will be refreshed with all the original clean, intact programs and it will run faster.

Avoid Standby Mode

One last thing is regarding the ‘Standby’ mode. It’s nice but it consumes battery power so you run the risk of reducing the life of your battery. Next time, use the ‘Hibernate’ mode instead of ‘Standby’. It preserves your laptop’s current state by writing it to the hard drive as a file. And it does not require any extra power. It takes a few extra seconds to use ‘Hibernate’, but it will extend your laptop battery life.

Conclusion

I hope you feel that this article has shown you some good tips for extending your laptop’s life. A laptop computer is a pricey investment; do your best to keep it safe and it will keep working for a long, long time.
