How Removing & Replacing A Power Supply Unit (ATX) On A Desktop Computer?

Replacing a Power Supply Unit (PSU) is a relatively straightforward procedure to carry out and this article includes a few useful hints and tips to help make the process as easy as possible, even for a novice.
Safety Precautions

Even when a PSU is not plugged into the mains, the capacitors inside the unit can still hold a potentially lethal electrical charge so it is vital that you must never disassemble the case of a PSU or attempt to force any objects (e.g. a screwdriver) into gaps within the unit itself.
Required Equipment

To successfully complete the instructions contained within this article you will need the following; a small philips screwdriver, an anti-static wristband and access to a digital camera.
1) Unplug Computer & Remove Panel

The first thing that you need to do is to unplug the PC, position the PC on a steady surface and take off the side panel, giving you a clear view of the components inside the case. The main side panel can usually be removed once two thumbscrews at the back of the PC have been removed.

2) Photograph The Internal Layout Of The Computer

This is a great trick for any beginner because it will offer a point of reference which you can refer to when fitting the new PSU. Using the flash, take a clear photo of the inside of the computer ensuring that the position of wires, connectors and components can be clearly seen. It may be advisable to take several photos from different angles to ensure you have a good photographic reference.

3) Take Anti-static Precautions & Unplug PSU Connectors

The next stage is to unplug the connectors from the power supply and it is strongly recommended to wear an antistatic wristband to protect you computer from electrostatic discharge (ESD). You should be able to easily locate the PSU; it is the square box positioned at the top of the case with numerous wires protruding from the front of it.
You will notice that wires are bunched together into small groups which connect to various components within the PC. Slowly trace and follow each set of wires to their termination, where they will be connected to a particular component via a plastic connector of varying shapes and sizes. Unplug these terminal connector and repeat this process for every set of wires exiting from the PSU. Once this has been completed you will have now disconnected the PSU from all components within the PC.
4) Remove The PSU 

Now that the PSU is disconnected from all other component within the PC it can be removed by unscrewing the four small screws located on the rear of the PC - there should be a screw corresponding to each corner of the unit. Once these screws have been removed you will now be able to remove the old PSU.

5) Fit Replacement PSU

The replacement PSU should have the exact physical dimensions of the original unit and all you will need to do is fit the unit into the case in the gap vacated by the previous PSU. Ensure it lines up with the four screw holes on the rear of the PC and then attach the new PSU into place using the screws removed in stage 4.

6) Connect PSU to Internal Components

Now that you have fitted the repacement PSU, the next stage is to connect all wires to their designated components in exactly the same way that the previous PSU was connected.
The wires on the replacement PSU should correspond to the wires on the older unit and there should be the same type and quantity of connectors present. The correct destination for each set of wires can be determined by matching the connector with the corresponding connection on each component inside you computer. If you have any difficulties with this stage then refer to the internal photographs taken in step 2 which can be used as a point of reference from which to begin connecting the PSU to the relevant components.
Once the PSU has been connected to all components, there may be everal small connectors which are unused - this is quite normal and should not be a cause for concern. Use cable ties or elastic bands to group together and neaten any leftover wires (this will also keep them out the way of other components).

7) Final PSU Check

Before you re-fit the side panel of your computer it is advisable to double-check and make sure all connections from the PSU are secure (the large connector entering the motherboard itself can be rather stiff and may need a firm push to ensure a decent connection). It is extremely important to check the voltage switch on the back of the PSU as these units can be configured to work on either 230 volts or 115 volts. Ensure it is set to the correct voltage setting for your power grid (consult the documentation of the PSU if you are unsure which voltage setting applies to you). Finally re-fit the side of the PC case, remembering to secure with thumbscrews.

8) Power On System

Attach the power lead to the mains and switch on your computer. Hopefully the system should start up as normal and begin loading your operating system. Ensure that all system devices are functioning properly (optical drives, Card Reader, system fans etc). If the system fails to power up correctly then unplug the PC from the mains, remove the side panel from the case again and check every single connection thoroughly - it is likely that you may have missed something (consult the photos and check every connector is in the correct place).

New ! features make the new Facebook

Facebook again will add new features on its website homepage. In their official blog, Facebook presents two features that are referred to the Trusted Friends and Passwords App.

Trusted Friends, created to help users gain access Facebook account back if they get forgotten passwords or other things. Relief works through a friend of the user who was entrusted to provide such access.

Facebook let users to select 3 to 5 friends they trusted. Well, when the user forgot the password to log in and can not access the email account, then they can be pinned their hopes on trusted friends.

Quoted from YahooNews, Friday (28/10/2011), Facebook then sends the code via email to 'trusted friends'nya that will help users access the account again. "This is the same as when you give the keys to a trusted friend's house when you go on vacation," the picture conveyed Facebook.

The second feature that is the App Passwords. Facebok realize that the moment will use third-party applications, most users want a different password to be able to wear them. Given, most applications require the user to enter a password before gaining access Facebook application.

With App user password is now possible to create a new password for logging into third-party applications. App Password can be used by clicking the Security tab and go directly to the App Passwords.

The plan, Facebook will be releasing these features in the next few weeks. Reportedly, now Facebook has been inhabited by more than 750 million users by half of whom log in every day.

Beginning of smartphones nokia

Finally Nokia is ready to compete in the world Smarphone, this is the beginning in nokia smartphones.          Nokia released the Windows-based smartphones du namely Nokia Lumia 800 and Nokia Lumia  710. 

The  features provided fairly complete. These are the details of the two smartphones nokia windows based.

Nokia Lumia 800

 

In terms of design, the Nokia Lumia 800 does not differ much when compared to the Nokia N9. But for specifics, there are some differences. Nokia Lumia 800 has been equipped with ClearBlack 3.7-inch AMOLED display (480x800 pixels) of the curve as well as Qualcomm's single-core processor 1.4 GHz with a graphics processor.
For multimedia, available 8-megapixel digital camera with Carl Zeiss lens and 720p HD video recording support. 16GB of internal memory is also available, which is supported with an additional 25GB of SkyDrive account to store images and music.
To access existing files on SkyDrive, you must connect to the Internet. Connectivity to the Internet is also quite good, because it has supported HSDPA 14.4 Mbps and HSUPA 5.76 Mbps and Wi-Fi and Bluetooth. Lumia 800 Nokia plans to sell about 420 EURO or about 5 million.

 

 

Nokia Lumia 710 

 

 

For those who like bergonta casing cover, the Nokia Lumia 710 to the right choice. For performance, it seems not much different 710 Lumia Lumia than 800 since they both use the same processor and both have 512MB RAM.
A little to distinguish, in addition to its design, is the ability of a 5-megapixel camera, Carl Zeiss lens without, and only 8GB of storage capacity. The price is quite affordable, around 270 EURO or in the range of USD 3.5 million. Both smartphones based on Windows Phone 7.5 has been equipped Nokia Mango Drive, namely navigation solution with voice guidance first for a Windows Phone device.
Interestingly, this facility is provided free of charge. For consumers Indonesia, unfortunately have to wait until early 2012 if you want to buy it. Interestingly, these two smartphones Lumia using Micro SIM card as found in the Apple iPhone 4. Apparently the Micro SIM card will also be a new trend in 2012.

Deciding upon Programming Language

Coders and web developers these days have one distinct advantage over their forebears mere decades ago - they're spoiled for possibilities. There are additional programming languages available now than before.

However, some have pointed out that it isn't how clean the code is that now hallmarks the expert from the amateur - code has a tendency to get cluttered regardless. It seems one of the major difference makers these days lies in knowing which language is best for what purpose.

As programming languages gain flexibility and are developed with compatibility in mind, it can sometimes surprise people to know that many still "specialize" in certain functions or have features that others don't have. This can usually be traced back to their origins and the decisions made while these languages were initially designed. While software development companies might have little practical use for a programming history lesson, knowing what one language was meant to do can help in deciding whether or not to use it for a project.

Java was a language meant for networking applications and will see a lot of focus as one of the "cores" of the upcoming Windows build. For most consumers, this is the language powering various little applications on the Internet, as well as the heart of a number of cross-platform programs from a variety of developers. The syntax is familiar to anyone who has dabbled in C and has a similarly high degree of allowed reuse of code, though has problems with efficiency. While its speed has improved over time, many developers still find that Java is problematic to code for and lacks the efficiency of other languages available.

C and C are two of the most popular languages, with the former having a particularly strong grasp on game programming. Programmers often find C-based programs run faster, while C is typically more efficient to code, with a structure that allows for a lot of code to be reused. There has been some debate between whether or not the repeatability of C makes up for how difficult it can be to code for it, and whether there are any subtle advantages offered that outweigh the superior performance of C. It should also be noted that C has the option to be coded in C style if necessary.

In contrast to most other languages, Fortran is most preferred by scientists and researchers, as well as anyone else that needs very precise values in their calculations. This is because it allows for a large number of high-value variables to be included, limited only by the memory of the machine. This makes it highly-prized among engineers, who require detailed precision in their number-crunching and mathematical models. However, for other applications, many programmers find it lacking. It lacks flexibility and the code itself must be written within a certain structure that increases the difficulty.

PHP is primarily used for website design, but unlike Java, was never meant to see use in other areas. It is simplistic and designed to appeal to even amateurs, who are known to pick up the basics with very little instruction. It was built for rapid deployment and design of websites and it shows; the language tends to lack utility for making anything else.

Pascal is often seen as a "student's language" because of its simplicity, which has led to a very low number of programs written with it industrially. It is easier to use than most other languages, but handles advanced techniques and concepts poorly. However, a more robust version called Delphi has received a push as language that can be used for industrial-grade programs.

Other languages not mentioned here have their own strengths and weaknesses, along with those that were designed for very specific purposes. Python, for example, is a fairly popular language that has gained traction in the gaming industry, while RGSS is intrinsically tied with the RPG Maker series. Since each language has its own capabilities, choosing one properly can make a project easier or harder.

choose the best printer toner cartridges for your printer

Tips to keep in mind while buying laser toner cartridge
Buying online is a good option when need a new laser toner cartridge for your printer as it is the most cost-effective and the easiest way.
Like your car that cannot run without gas, your printer cannot run without the cartridge inside it. You have to choose the appropriate one for your printer. It is easy; you have to match the numbers and letters. The manufacturers have made your work less tedious. There are several companies like IBM, HP, Brother, Epson and Xerox that manufacture laser toner cartridges. These are available from various online stores available at a cheaper rate offering the same superior quality.
The most important thing about printer toner cartridges is that you must know the one that is fit for you; in other words, you must know the cartridge make number and type that is compatible with your computer besides the manufacturer. It ought to be economical and of course reliable. You have to open the printer and check the model number of your ink toners. Then surf online to get the product you want. You have to match the model number and make and then order the right replacement online. Make sure that if you order in bulk for your office you get a discount.
These days most of the printer manufacturing companies are coming out with laser printer toner that will go with more different models of the same brand. Alternatively, there may be printers where you can use more than one type of cartridges. The instruction manual of the printer can guide you. If you can preserve the original cartridges of the printer and their packaging; it will be of great help.
Research online, the vendors that supply printers have websites that have charts showing compatibility between the manufacturers of major printers and the re-supply products of the company.
If you are in need laser toners in bulk, then you can buy at wholesale prices. This is the ideal way to purchase toners when you are running a business. However, if you want to buy for use at home, you need not go for this option.

The best way to buy a laser printer toner is to go for the online option. In Australia, you can find many online shops that sell laser printers toners. However, before you buy just ensure the following:
• The online store should be reliable and reputed
• Pricing should be good; go for the one that offer "retail @ wholesale price"
• They should offer home delivery
• Check whether the store offers warranty options (on site) or not
• The store should offer wide range of top brands of printer toner cartridges manufacturers
• There should be a secured online payment processing facility in the site
Finally a piece of suggestion; when you buy a new laser printer toner cartridge, you will be left with the old one that has served you for so long! Dispose it off in an honorable way, i.e. destroy it in the most environment friendly way. For that matter, you can always get in touch with the manufacturer or the supplier of the cartridge.

Make The Program Find The Area And Circumference Of a Circle With c

As a start I'll explain a little history of C + +. C + + is a programming language, computer C + + was developed at Bell Labs (Bjarne Stroustrup) in the early 1970s, the language is derived from the previous language, namely BCL, At first, the language is designed as a programming language that runs on Unix systems, the development, version of the ANSI (American National Standard Institute) C programming language became the dominant version, Though this version is now rarely used in the development of systems and networks as well as for embedded systems. In C + + added new concepts such as classes with properties such as inheritance and overloading. One of the most fundamental differences with the C language is support for the concept of object-oriented programming (Object Oriented Programming).

above is a little description about the C + +, this time we just make the program find the area and circumference of a circle. This is a script-script:

#include <stdio.h>
    int main (void){
        float a,luas,keliling;
           printf("Masukkan Jari-Jari = ");
           scanf("%f",&a);
                luas = 3.14 * a *a ;
                keliling = 2*3.14*a;
           printf("Luas Lingkaran =%.2f\n",luas);
           printf("Keliling Lingkaran =%.2f\n",keliling);
    return 0;
    }

so this tutorial from the coding Edan, if there are errors or wrong words please understandable because it was a newbie.

I shall see in the next tutorial :D

Making a simple calculator

Microsoft Visual Basic (often abbreviated as VB only) is a programming language that offers Integrated Development Environment (IDE) to create visual-based software program Microsoft Windows operating system by using a programming model (COM).

Visual Basic is a derivative of the BASIC programming language and offers computer-based software development graphs quickly.

On this occasion I will share a little knowledge about desktop programming
I'll give an example to make a simple calculator using visual basic 6.0

1. you open the Visual Basic 6.0

 

2. then select standart.exe only

3. make the design of the calculator by using

• 3 Label
• 3 TextBox
• 4 CommandButton

Change the Caption on Label1 = number1, Label2 = angka2, Label3 = Results. Next change the name in textbox1 = txtangka1, textbox2 = txtangka2 and textbox3 = results. change is also part commandbutton1 = cmdtambah, commandbutton2 = cmdkurang, commandbutton3 = cmdkali, commandbutton4 = cmdbagi.
captionnya change so it becomes like the image below.

 
4. Double clik on cmdtambah, cmdkurang, cmdkali and cmdbagi. then write the following coding:
  
cmdtambah :


hasil = Val(txtangka1) + Val(txtangka2)
txthasil = hasil
  
cmdkurang :


hasil = Val(txtangka1) - Val(txtangka2)
txthasil = hasil


cmdkali:


hasil = Val(txtangka1) * Val(txtangka2)
txthasil = hasil


cmdbagi :


hasil = Val(txtangka1) /Val(txtangka2)
txthasil = hasil


5.  Save Preject above with the name Calculator. select where to store your own.


6. Run or press the button (F5). and the results are as shown below.

Thus visual basic tutorial, hopefully useful apologize if there are errors.

The company will launch the Nokia Mobile based smart phone windows phone "Mango" next week in London at the same time reported a third quarter loss.Investors hope Nokia can take advantage of the shift rulers dominated the smart phone industry of Apple and Google, Reuters reported.Sales of smart Pomsel nikia weakened because it depends on the platfrom symbian which is rarely used. nokia therefore an agreement with Microsoft in February.Analysts estimate Nokia only sold 15.9 million smart phones in the third quarter, the figure was down 40 percent from a year ago. Although Nokia has cut the price of smart phones in early July."The biggest question is whether we see the basic problem of a smart phone? I think we did it," said Swedbank analyst Jari Honko.Because the smart phone sales continue to weaken, Nokia will report third-quarter operating loss of around 23 million euros, down 391 million in the previous quarter.With Microsoft software, Nokia hoped to break Apple's and Google's attention and attract the software developers to join.So far the success of Windows Phone is still a question mark and only 2-3 per cent market share. It was 180 degrees with a share versus Google Android at 50 percent and Apple's market share by 15 percent.Investors were disappointed because Apple Apple iPhone sales dropped to 17.1 million units in the September quarter, but the figure is still far from Nokia sales expectations. 4S iPhone sales Apple's previous record sales.Nokia does not rush the latest issue of smart phones despite the holding of Microsoft.

History Of Android

Android is the operating system for mobile phones based on Linux. Android provides an open platform to developers for creating their own applications for use by a variety of mobile devices.
