Installing a CD or DVD Drive



Preparation

So you want to install a CD drive? Well the first thing you need to do is have a CD/DVD drive to install. So why not go to my page on CD drives and consider what drive you need.

Do you need a SATA or IDE drive? Do you want a DVD burner or a CD Burner? Does it need to play all type of DVDs? Do you need a blu-ray drive? These and more are the questions you need to ask yourself before you choose your drive.

Locating the CD/DVD drives

The next step in this tutorial on installing a CD drive is to locate the CD drives on the computer case. The way to do this is to remove any cables that you may have attached, open up the case and take a peak inside. I would recommend that you wear an antistatic wrist strap while doing all this.

So once the case is opened take a look and hopefully you will find something that looks similar to the photo below.



Setting the Jumpers

This step is probably the most difficult step in the entire tutorial. However the newer SATA CD/DVD drives do not require you too set the jumpers so if you are using a SATA drive, you can skip this whole step. However if you are using IDE drives then you will need to set the jumpers.

To work out where the jumpers need to go you need to ask this question. How many drives (including hard drives) do you want to have in the computer?

If you only have two drives then you can leave the jumpers as default and just put each drive on a different cable. For example: One hard drive on one IDE cable and one CD drive on another IDE cable.

However if you want to have three or four drives then it is necessary to have two drives on the one IDE cable and then you need to set one drive as master and another as slave.

The image below should help you identify where the jumpers are on an IDE CD/DVD drive.

Inserting the CD/DVD Drive

This step is the actual installing of the CD drive. So take the drive place it in its slot and push it in. Put the screws in place and your done.

Installing the IDE cables

In this step we are simply connecting the cables from the motherboard and the power supply to the CD/DVD drive. The cables from the motherboard will either be the SATA cable or theIDE Cable. And the power cable will either be the normal peripheral power cable or the SATA power cable. So if you are using an IDE CD drive then you will use the IDE cables and those with the SATA drives will use SATA cables.


In the images I will be using the IDE cables but connecting SATA cables is very easy so you should have no problems.

Connecting the IDE Cable

installing the ide cable

To connect the IDE cable simply place the IDE cable in the motherboard (like the image shows) and place one of the other ends into the CD/DVD drive.

Often the IDE cable will only go in one way.

Note - SATA cable users: The sata cable is very easy to install. It will only go in one way and you can see the SATA ports on the right (the red ports) in the image.


When inserting the IDE cable into the CD/DVD drive always place the red wire of the IDE cable closer to the power cable.








Connecting the Power Cables

The next step in this tutorial on installing a hard drive is to connect the peripheral power cables. These will only ever go in one way and you can find a tutorial with images here.

Peripheral Power Cable (4 Pin)

 A peripheral power cable is used to connect the older IDE hard drives and cd/dvd drives to the power supply. There are four cables (1 yellow, 2 black and 1 red). Sometimes there are eight cables, this happens when there is another cable coming out of it to connect to another hard drive or cd drive.


These peripheral power connectors were the original power cables in a computer and were used most commonly for hard drives or cd drives. However, they are sometimes used in an array of tasks in the computer: additional motherboard power, video card power, fans, lighting etc.

This cable is commonly called the 4 pin molex power cable, but this can be confused with the 4 pin main power cable which is a molex cable too. This power cable can sometimes be found with only two cables. This version of the power cable is for fans in the case so do not attach it to your hard drive or cd drive.

The picture above explains how to install the peripheral power connector into a hard drive. To see a photo of the cable being connected to a cd drive click here.

The first step to connecting power to a hard drive is identifying the 4-pin peripheral cable. Next get the hard drive you are connecting to and place the power cable inside the hard drive like the photo demonstrates. The power cable will only go in one way and the yellow cable(s) will be closest to the edge of the hard drive.

BLOGING

What Does Blog Stand For

 Every person who uses the Internet today knows what a blog is, but have you ever wondered what does blog stand for? There have been various full forms that have been suggested for blogs, but the original meaning is said to be 'Web Log'. This term was coined in the year 1997 by John Barger. 




Today people are completely familiar and comfortable with the term blog and what it represents. It is an online journal of sorts that has given millions of people around the globe an opportunity to explore their creative writing abilities. If you still do not know what does blog stand for and what it does, let me tell you that it is a revolution that has changed the literary habits of the world, and has brought every single person that little bit closer. 

People love making journals and memoirs about their lives, their travels, their aspirations, or simply about their thoughts. Becoming a writer meant that you needed an exemplary command over words and the English language, and the ability to sweep people off their feet with your lengthy narrations of purple prose. But high speed Internet has changed everything. Shorter, smaller and faster was the new mantra, and blogging took the world by storm. It paved the way for individuals of moderate literary talents to get their work published and viewed by millions around the world, and gave them a platform for 'creative expression'. 

What Does Blog Stand For?

For people who are new to the world of the Internet, the term blog holds a lot of mystery and fascination. Though originally the word blog was coined to imply 'Web Log', over the years there are many more acronyms that the term has been associated with. Here are a few more acronyms that the term blog stands for.
  • Better Listings on Google
  • Big Load of Gossip
  • Boring Lump of Garbage
  • Boring Lessons on Galaxy
  • Biological Links on the Globe
  
  Going through these supposed acronyms, one can see that the term blog is not something that is related to serious literature. Of course, there are few individuals who make use of this platform for very good purposes, but all in all, this platform has disturbed the equilibrium of genuine content. There are no regulations regarding the material that can be published on a blog, and as a result you will come across a lot of incoherent and inconsequential gibberish on most blogs. People will argue that this gives the world a stage to express themselves, but I want to know what use is it to me to read about what a teenage girl in Tokyo ate for breakfast today, and how her mood is. This is all 'chatter' (useless noise), which the Internet is guilty of inventing. So what does blog stand for? That depends on your perception. 

History of Blogging

When the Internet first began functioning, starting a new webpage was a tedious process and took plenty of time. As time went by this process got easier and shorter, and pretty soon it was just a matter of a click. The history of blogging tells the story of how it has become easier and simpler to start your own webpage, and even your own website. After the term was coined in 1997, it was regularly used in circles that were familiar with the Internet. 

In 1999, Peter Merholz, broke down the term web log into 'we blog'. This soon became the rage and the term began to be used more as a verb. To blog now came to mean to create or edit your web log. The use of these terms was so widespread and common now, that by 2003 the Oxford English Dictionary had to include it in their new version. Pyra Labs created a software known as Blogger, which was subsequently purchased by Google, and this interface made it possible for everyone with Internet access to create their own blog. 

Read more on:
Now, what does blog stand for? It stands for the advent of Internet technology at such an alarming rate that we are constantly trying to catch up. It stands for a platform where there are no barriers and no regulators and moderators and other forms of Internet censorship. You're free to write what you please, and it is the choice of the reader if they read it or ignore it. The power is ultimately in your hands though, and what you do with it is completely your call.

Sadiq's Blog: SMPS (SWITHING MODE POWER SUPPLY)

ATX Power Supply Repair And Troubleshooting Secrets That You Should Know



I had stopped repairing ATX power supply many years back due to the new one cost very cheap. It’s not worth to repair it because the spare parts sometimes were much more expensive than getting a new power supply. Searching for ATX power supply spare parts was not easy as many of them you can’t even find them on the internet. Not only that, many complicated and different designed by power supply manufacturers had eaten up our precious troubleshooting time too because of we need time to understand how all these different designed power supply work.


Some of the power supply designs were using the PWM IC (UC3842) and power FET, some use the double transistors while some use only a single power IC in the primary side. Because of the manufacturers wants the design to be made into compact size, many secondary or even primary power supply circuit were build into a modular board (smaller board). This made troubleshooting even more difficult because many times the meter’s probe can’t reach to the testing point.

The real reason why I had stopped repairing ATX power supply was the profit margin. If you charge to high the customers rather buy a new unit with one year warranty given. If you charge too low, you may end up in the losing side because of the components replaced, electricity and etc. If you charge reasonable, the profit margin gained can’t even cover your time spent on troubleshooting it. I’m here not to discourage you to stop repairing ATX power supply, however if you have the time, have contacts getting cheap power supply components, easy to access many power supply schematic diagrams and etc then you may go ahead to repair it.


Okay back to the article, one of my customers had asked me to repair his ATX power supply. I told him to get a new one (since it was very cheap) but he said he couldn’t find one that suits his customer’s CPU. He wanted a power supply that is either same size or smaller then the original one with same or higher specification but all he could find was a standard size power supply! 



As a favors to my customer, I would do my best to help him to repair the ATX power supply. When the power supply was switch on, measurements were taken. The results were over voltage. The 12 volts line shot up to 13 + volt and the 5 volts line became 5.6 volts. After the casing was removed, I found the inside was very dirty and I used a vacuum cleaner and a brush to clean off the dirt. Then I saw four filter electrolytic capacitors had bulged at the top casing.




As you know, we as electronic repairers can’t just see things at only one side; we have to see the other sides too. What I mean was, try to see if there are any suspicious components that contributed to the failure of the power supply such as broken components, dry joints, loose connection, decay glue and etc before start checking the suspected area. 



What I saw was at the primary side there were some components covered with decayed glue as seen in the picture. I have to carefully remove it by scrapping off the layers of the decayed glue while preserving the outer layers of the components. Once it was done, I clean it with the Thinner solution. Decayed glue could cause serious or intermittent problem in electronic equipment because it can be conductive. 


If you repair any ATX power supply, make sure you check the fan too because some power supply failure was due to heat caused by a faulty fan. The purpose of the fan is to suck out all the heat generated by the components inside the power supply. In order for the fan to run smooth, you can service it by using a Philips oil base spray as shown in the photo. 




Once the four electrolytic capacitors were replaced and the decayed glue removed, I then have to plug it into a junk motherboard together with a hard disk to test the performance of the ATX power supply and measure all of its output voltages. It seems like the output voltages were back to normal. Once everything is okay I then test it in a working CPU to check for the display.


The reason I test it with a junk motherboard first as a way not to cause my good motherboard to go bad just in case if the output voltages is still very high. Better safe than regret later. By the way you can’t test a power supply without load otherwise it may turned on for a while and then shut down. If you do not have a junk motherboard you can always at least connect a hard drive and a wire jumper to its connector to turn on the ATX power supply.


Do you know that most ATX power supply is using dual Schottky barrier rectifiers to convert the ac wave into DC voltages? Even in LCD Monitor power supply, a dual Schottky were used in the rectification too. For your information, checking Schottky diode is different from checking a normal diode. With analog meter set to X10 K ohms, it should show some leakage reading when doing the reverse bias test. If this component becomes faulty it is very easy to get a replacement, of course you have to get one with the right specification. That’s all for today, hope you enjoy the article and come back more often to check out for any latest repair techniques that I’m going to share to you.

SMPS (SWITHING MODE POWER SUPPLY)

  SMPS - A switched-mode power supply (switching-mode power supply/SMPS or simply switcher) is an electronic power supply unit (PSU) that incorporates a switching regulator in order to provide the required output voltage.

 Every electrical or electronic device needs power for work and the computer is not exception to it. Computers, too, have a particularly designed power supply component known as Switch Mode Power Supply (SMPS). SMPS converts raw input power to controlled voltage and current for the operation of various components of the computer. SMPS uses switches for high efficiency. The primary function of SMPS is to convert the alternating current (AC) power available in homes into direct current (DC) required for a computer system. In desktop computers, a metal box found in the corner of the CPU case supplies power to various components in the CPU box. The power supply converts 115-230 volt AC into DC that is required for computer components to work.


The terms such as voltage, AC, DC, etc., are closely associated with the power supply or SMPS.
Voltage is an electric potential difference between two points and is measured in volts.
AC stands for alternating current. It is an electric current whose magnitude and direction vary cyclically.
DC stands for direct current. It is considered as the constant flow of electrons in a single direction from low to high potential. Computers use DC power. Because of the advantage of alternating current over direct current in transforming and transmission, electric power distribution today is nearly everywhere alternating current.
The SMPS or power supply of a computer comes in different form factor styles. The form factor refers to the physical dimensions of a component. The form factor of the power supply must match with the form factor of the computer case into which the SMPS is inserted. There are various industry standard form factors available. Some of the commonly used form factors with their characteristics are given below:
  • ·        LPX
  • ·        ATX
  • ·        SFX

The LPX form factor style power supply has exactly the same motherboard and disk drive connectors as the previous standard power supply form factors. LPX form factor power supply differs in its reduced size that allows building much smaller and consumer oriented PCs. Due to their small size, they can be put into almost every type of computer cases.
The ATX form factor is developed by Intel in 1995. ATX is similar to LPX in physical dimensions. The difference between the two is that the power pass through-outlet for the monitor has been removed from ATX. Another difference is that in ATX, the cooling fan is mounted along the inner side of the power supply. With this kind of arrangement, the fan draws air in from the back of the chassis and blows it inside across the motherboard.
The SFX form factor style power supply is 100 mm wide, 125 mm deep, and 63.5 mm in height. It includes a 60 mm power supply fan for cooling. The main SFX motherboard connector is in the same shape and size as the ATX connector. The one difference here is that the SFX power supply specification does not support the -5V compatibility voltage and, therefore, should not be used with motherboards that have ISA slots.
Each SMPS or power supply on a computer contains a connector that connects to the motherboard, which supplies power to the system processor, memory, and all add-on cards connected to slots such as ISA, PCI, AGP, etc.
Industry standard PC, XT, AT, and LPX motherboards use the same type of main power supply connectors. They use two main power connectors: P8 and P9. Each of the P8 and P9 connectors has 6 pins that connect power supply to the motherboard.
ATX main power connector is used to connect to the power connectors on the ATX, SFX, and in all ATX based motherboards. ATX main power connector is a 20-pin connector with a square hole for pin #1 and round holes for the other 19 pins.
ATX auxiliary power connector is a 6-pin connector. Intel designed this to fulfill the additional power requirement of motherboards, e.g., a motherboard that requires 18A of +3.3v or 24A of +5v power. A higher level of power is required when power supply system is using 250 watt to 300 watt supplies.
ATX12V power connector provides localized power to the CPU, while the AUX connector provides additional power mainly to the AGP card.
The computer components and circuits such as motherboard, adapter cards, and disk drive logic board use +3.3v or +5v, and the disk drive motors and cooling fans require +12v power. The components that require voltage level other than this are powered through onboard voltage regulators. These voltage regulators are built into the motherboard.

Different view of SMPS --
A Switch Mode Power Supply



The Back Portion of a Switch Mode Power Supply Section

Power Good Signal: The power supply not only converts AC to DC but also ensures that the system does not run unless the power supplied is proper. Power supply conducts an internal check before the computer starts. If the check is successful, it sends a signal called Power Good to the motherboard. The Power Good signal is present in the system. When the AC voltage dips and the power supply is unable to provide outputs, the Power Good signal is withdrawn and the system is reset. The Power Good signal is a +5v active high signal, which is supplied to the motherboard after the internal checks have been successfully performed. The processor timer chip present on the motherboard that controls the reset line receives the Power Good signal. After receiving the signal, it releases the reset line, and the CPU starts executing the code present at FFFF:0000 memory address (ROM BIOS).
Power supply transmits power not only to the motherboard but also to the floppy disk drive, hard disk drive, and CD/DVD drive and other devices. A four-wire connector is attached at the back of each drive. The four wires provide +5v, +12v power, along with two grounds, to the various drives that use them. The connectors are available in two different sizes. The large size connector known as Molex is used on most internal drives, including hard disk, CD/DVD, Zip drives, and the older 5.25 floppy disk drives. The smaller size power connector, called as Berg, is used for the newer style of 3.5 floppies.

Serial-ATA (SATA) power connector is used to provide power to SATA hard disk drives.
The number of power connectors on the power supply varies with the type of power supply. If the power supply is large, the connectors are more in number so that more devices can be attached to it.
Power supplies have many other specifications and features to protect computers. A good power supply should have very low current leakage, i.e., less than 500 micro amps, to ground.
While adding add-on cards or other components on a computer, a technician should make sure that the power supply is not overloaded. Most of the time the power supply is overloaded by filling up the expansion slots and adding more hard disk or CD-ROM drives. Today’s processors may also have high current requirement for the +5v or +3.3v supplies. Therefore, when selecting an SMPS for a computer, technicians should have future system upgrades in mind.
In case of a defect or problem with power supply, it is not recommended that an inexperienced user open a power supply for repairing. The power supply has dangerously high voltage. Even after unplugging, power supplies can retain dangerous voltage and must be discharged (like a monitor) before servicing it. These internal repairs are not recommended unless the technician is specially trained to repair such components.
