Buying a Refurbished Laptop Computer

By admin

When considering buying a used or even a new laptop, the first thing you need to do is to determine your computing needs.

* word processing
* e-mail
* browsing web pages
* moving the laptop from home to work (weight)
* gaming
* on-line shopping
* a database application
* personal finance
* is battery power important

Check out the Minimum Systems Requirements needed to do all of the your applications. They will not come with the laptop, as refurbished laptops often only include the Operating System (OS). If they don’t include an installed OS, then be prepared to install it yourself. This is not for those that don’t know what they are doing, so research what is involved before buying one without an OS.

Once you understand what you really need, you need to determine your budget.

Most old laptops do not have working batteries. If you need a battery, shop around to figure out how much they cost. You should know that on older laptops, batteries don’t last more than an hour or two, so purchasing a new battery for the purpose of longer battery life may not be worth the expense. And by all means, stick with a name brand IBM, Dell, Toshiba, Compaq-HP.

If you are new to computers and you want to browse the World Wide Web, you will need to obtain the services of an ISP (Internet Service Provider). There are basically two types of Internet access options: broadband (cable modem, DSL, satellite) and lowband (dial-up). Broadband is the preferred type since download speeds can range from 128kbs to 6000kbs. The faster the better, of course. But, if your budget is tight, dial-up works just fine for typical browsing and e-mail usage.

Your choice of ISP’s will be dependent upon two things: budget and location. If the budget allows and you don’t mind paying upwards of $35-50+ per month, you can purchase a broadband connection. However, even if money were no object, your physical location will determine what types of services are available to you. Broadband is not available everywhere (with the exception of satellite). If you have a telephone line, you can always choose dial-up. AOL’s bread and butter is dial-up users. Do your research to determine what is available in your area and compare costs.

And for you gamers out there, you definitely need a reliable broadband connection. Gaming over a lowband connection can be a frustrating experience and sometimes even impossible. You will need to check out the minimum systems requirement for the games you are interested in using to make sure the CPU speed and the RAM and graphic chip requirements will support the games you wish to play.

Once you have figured out your budget and your needs and the requirements of your laptop it is time to search for the laptop of your desires.

Some people choose to search at www.ebay.com. If you do be sure to check out the seller to be sure you will have a smooth transaction.

Many people don’t want the hassle of bidding, so use your favorite search engine: Google or Yahoo or MSN for the terms “used laptops” or “refurbished laptop”.

An important thing to keep in mind is how will the vendor treat you should there be a problem. If you don’t like their attitude or they don’t pick up the phone shop elsewhere. Price is important, but if you have a problem and spent the least amount of money possible the vendor may not have any resources available to help you after you have purchased and spent your money.

If all the above seems like too much of a hassle, then buy a new computer. It will cost around $700 + but will come with a new battery and a one year warranty, although some new ones seem to have only 90 day warranties. It will also have the latest Windows XP system and an 800 number to call the vendor, should their be a problem. I’d call the 800# first before buying to get an idea what kind of support they will provide.

Choosing the Right Motherboard for you

The motherboard is the heart of any computer. It is that big flat board inside the computer that everything is connected to. It performs the role directing information and connecting components. A motherboard is often overlooked when choosing components. This is a scary thought as the motherboard determines system performance as much as every other component.

Choosing the right motherboard does not have to be a problem, even though there is a lot to consider. We will start off with the larger parts and move onto the things that are less essential.

Firstly is the socket type. The socket is where the processor (CPU) connects to the motherboard. There is no compatiblility between sockets, so it has to be the right one. The socket connection needs to match the connection of the processor you have or the one you intend to buy for the computer.
Most older Intel Pentium 4s utilize socket 478. Newer ones use socket 775. AMD chips utilised socket A for a long time, but now the AMD Athlon 64 series and Semprons use socket 939. Just check with someone as to what yours or your intended one will have.

Your choice of chip will have a lot to do with your needs, but choosing one with an up to date socket type will ensure slightly longer motherboard life as you can upgrade the chip for a while.

DDR is the RAM of choice for most systems, but some newer systems, which includes all Pentiums with socket 775 use DDR2. These two kinds are not interchangable and have a different number of pins. Both DDR and DDR2 come in different speed ratings measured in MHz. DDR has a usual 400MHz denoted as DDR400 or PC3200, while DDR2 can go a little higher and comes in slightly faster speeds. Just make it match what the board needs.

A motherboard must be chosen carefully, to both match all the other components and fit in the case you choose. A little bit of research before you buy will save a lot of hassle later on.

Watch Live TV For Free Online – Get Connected Today

By admin

Mar 2010

There is a lot of talk at the moment about whether it is possible and legal to watch live tv for free online or not. There are a plethora of sites out there that offer this possibility, but it seems hard to imagine that you can gain access to thousands of channels using just your computer.

It must be said now that 95% of sites that offer this capability do not deliver what they promise. They claim to supply you with XYZ, and after you have taken out your credit card and paid, you are bitterly disappointed with the lack of channels and the quality.
However, they are a small number of sites that can give you what you want, that being live TV for free from your computer.
If you are new to the opportunity of watching live TV for free online, let me cover a few areas to clear your mind of any questions you might have:

What You Need

When you sign up to a creditable web site offering such a service, you will need to download their software which is usually very small and does not take more than a few minutes to install.

Once you have done this, all you will actually need from then on is a computer, whether it is a PC or a laptop, preferably a fast internet connection, and a free media player package like RealPlayer or MediaPlayer which you can download for free from their relevant sites.

With regards to an internet connection, the faster the internet connection the faster you will stream. As a result, you will receive a higher quality picture and sound to go with it. With a decent connection, you can watch fantastic television on full screen. The capability is there.

It will work from a dial-up computer, and you can still enjoy the benefits but broadband speed or higher is certainly recommended in order to receive full value.

Financial Aspect

99% of the time, you will be asked to pay a small one time fee, and from then on you will be able to watch TV for free. Do not sign up to web sites that want you to pay a subscription charge or monthly fees because that is not how the industry mainly charges for such services.
Sites asking for ongoing fees are, to be frank, being greedy.

The Freedom It Offers You

If you have picked the right package (very tricky these days), then being able to watch TV online offers you substantial freedom and other benefits. You can watch exactly what you would like to watch without others changing the channel. This is especially useful when you have a family, and each person wants to watch something different.

If you do not actually have cable or satellite in the first place, then such a service gives you this for a very small fee. With technology these days, you can connect yourcomputer to the television easily and reap the same rewards as you would if you were paying high monthly fees for cable!

There are many more benefits which I am sure you can think of, but ultimately it comes down to more freedom and flexibility for you.

Bluetooth And Infared

Sep 2009

With new electrical devices being produced every day,
the problem of connecting things is becoming more
and more complex in nature.  The system that comprises
computers and other electronics makes use of varieties
of wires, cables, etc.

These parts will communicate through light beams,
lasers, radio signals, and infrared.  The problem
however, is the devices and technology is often the
connection between each component.  Therefore, most
electronic systems aren’t used to their full extent
due to the problems and imperfections.

To help simplify things, a solution was created -
the solution of Bluetooth.  Bluetooth is wireless
and automatic, offering users a variety of features
that have simplified the art of connection.  Bluetooth
has revolutionized the standard methods of connecting
things to enabling almost anything to be connected
to a single system.

Aside from Bluetooth, there are other ways of
connecting wireless devices.  One example of such
is the IR or infrared.  Infrared allows low frequency
light waves to transmit signals to another component.
This technology is easy to create and the cost of
putting the IR device into a system is rather low.

Infrared technology is a one to one process.  Due
to the limitation, you may only send signals from one
device to another, similar to a television set and
remote control.  You can only transmit signals
between the two although not with a seperate system.

Aside from the fact that these two natures of
infrared are obstacles to acquiring results, these
same qualities have worked in advantage to the
connection.  Infrared devices need to be lined up
directly, meaning too little interference can occur
between the transmitters and receivers.

The technology behind Bluetooth works by transmitting
signals through low frequency radio signals.  The
path of communication is working on 2.45 GHz, which
is the same frequency band used in ISM devices.
