PART-A (Computer Servicing Practical’s)

Ex.No:1(A).Front panel indicators & switches and Front side & rear side

Connectors.

Aim:

To identify the front panel indicators and switches and rear side connector in a

computer system.

Procedure:

Tower Case:

Hard Drive Activity LED:

LED provides visual indication that data is being read from or written to the

hard drive.

Reset Switch:

Supporting the reset function requires, a momentary-contact switch that is

normally open. When the switch is closed, the board resets and runs POST.

Power Switch:

Supporting the power on/off function requires, a momentary-contact switch

that is normally open. The switch should maintain contact for at least 50 ms to

signal the power supply to switch on or off.

Drive bays:

Drive bays are most commonly used to store disk drives, although they can

also be used for front-end USB ports, I/O bays, card readers, fans, tool storage,

and other uses.

5.25" - Full-height bays were found in old PCs in the early to mid-1980s.

They were approximately 3.5" high by 5.75" wide, and used mainly for hard

disks and floppy disk drives. Half-height drive bays are approximately 1.75"

high by 5.75" wide, and are the standard housing for CD and DVD drives in

modern computers.

3.5" - 3.5" bays, their actual dimensions are 4" wide by 1" high. Those with

an opening in the front of the case are generally used for floppy or Zip drives

Front Side Connectors:

USB Connectors:

USB (Universal Serial Bus) is a way of setting up communication between a

computer and peripheral devices. USB is intended to replace many varieties

of serial and parallel ports. USB can connect computer peripherals such as

mice, keyboards, PDAs, gamepads and joysticks, scanners, digital cameras,

printers, personal media players, flash drives, and external hard drives.


4

Card Reader:

Card reader" is used to reads flash memory cards. It can be a standalone

device that connects to a computer via USB or it may be integrated into a

computer, printer, or multifunction device

Most card readers accept multiple memory card formats, including compact

flash (CF), secure digital (SD), and Sony's Memory Stick.

Audio Jack:

A socket for plugging in an audio source, Audio jacks are found on many

types of audio equipment and musical instruments that accept external

sound sources.

Rear Side Connectors:


5

PS/2 Port:

The PS/2 standard, introduced by IBM in 1987, stands for Personal

System/2. A PS/2 port is an electronic receptacle or plug found on

computers. It accepts a PS/2 cable with a mini-DIN connector, and is most

often used to plug in a keyboard or mouse.

The connector is small with a diameter of about 1/3 inch (9.5mm). It

features a metal sleeve that is notched to ensure proper alignment when

inserting it into the PS/2 port. This protects the circular pins inside the DIN

connector from becoming bent.

Parallel Port:

This interface is found on the back of older PCs and is used for connecting

external devices such as printers or a scanner. It uses a 25-pin connector

(DB-25). The latest parallel port standard, which supports the same

connectors, is called the Enhanced Parallel Port (EPP).

Serial Port:

The serial port is used for peripherals such as mice, gaming controllers,

modems, and older printers. It is sometimes called a COM port or an RS-232 port.

1(B).Familiarize the computer system Layout: Marking positions of

SMPS, Motherboard, FDD, HDD, CD, DVD and add on cards.

Aim:

To familiarize a computer system layout and mark the positions of SMPS,

Motherboard, FDD, HDD, CD / DVD drive and add on cards.

Procedure:

Motherboard:

The motherboard has been an integral part of most personal computers. The

motherboard is a common circuit board. Each circuit card performs a unique

function in the computer and gets its power from the socket.

CPU:

The CPU, or processor, is the heart of your computer no matter what type

(PC, Server, and Laptop). There are many brands for processors such as Intel and

Athlon all with different processors for your computer.

RAM:

Random Access Memory (RAM) is the form of memory contained in most

computers. When an application is running it stores its information in the RAM.

When you close the application the information is deleted from the RAM.

Hard-Disk Drive:

A hard drive stores all your files and information in a permanent form unlike

storing it in RAM (which is temporary). The larger your hard disk (drive) the more

information and files you're able to store.

CD-Rom:

The CD-Rom is reads CD's. CD-Rom completely stands for Compact Disk

Read Only Memory. CD's have much more data than a floppy disk. Using CD-RW

you can make your own CD's and use them more like a floppy disk.

CD-Rom: CD-disk

IDE cable : SATA cable

DVD-Rom:

DVD-ROM is a digital optical disc storage format. DVDs offer higher storage

capacity than compact discs while having the same dimensions. Blank recordable

DVD discs (DVD-R and DVD+R) can be recorded once, Rewritable DVDs (DVD-RW,

DVD+RW, and DVD-RAM) can be recorded and erased multiple times.

Floppy Drive:

A floppy drive reads the popular floppy disk. Floppy disk is easy to use,

rewritable, compact, and great for storing information. The floppy drive is simple

and allows you to read, write to, and write over information stored on a floppy disk.

Ensure that it

detects your new

hard drive.

If it doesn't detect the

drive, go back and make

sure the cables are

inserted tightly.

2(C).Partition and Format Hard Disk:

Create and format a hard disk partition:

You must be logged on as an administrator to perform these steps.

To create a partition or on a hard disk, there must be either unallocated

(empty) space on the hard disk or free space within an extended partition on the

hard disk.

If there is no unallocated space, you can create some by shrinking an

existing partition, deleting a partition, or by using a third-party partitioning

program.


19

To create and format a partition (volume):

Open Computer Management by clicking the Start button, clicking Control

Panel, clicking System and Maintenance, clicking Administrative Tools, and then

double-clicking Computer Management.

1. In the Navigation pane, under Storage, click Disk Management.

2. Right-click an unallocated region on your hard disk, and then click New

Simple Volume.

3. In the New Simple Volume Wizard, click Next.

4. Type the size of the volume you want to create in megabytes (MB) or accept

the maximum default size, and then click Next.

5. Accept the default drive letter or choose a different drive letter to identify the

partition, and then click Next.

6. In the Format Partition dialog box, do one of the following:

If you don't want to format the volume right now, click do not format

this volume, and then click Next.

To format the volume with the default settings, click Next.

7. Review your choices, and then click Finish.

To format an existing partition (volume):

Formatting a volume will destroy any data on the partition. Be sure to make

backups of any data you want to save before you begin.

You cannot format a disk or partition that is currently in use, including the

partition that contains Windows.

Quick format is a formatting option that creates a new file table but does not

fully overwrite or erase the volume.

1. Open Computer Management by clicking the Start button , clicking Control

Panel, clicking System and Maintenance, clicking Administrative Tools, and

then double-clicking Computer Management. If you are prompted for an

administrator password or confirmation, type the password or provide

click OK, and then click OK again.

2(D).Identify Master /Slave / IDE Devices:

How to Set Jumpers for Your Computer’s IDE Drive:

SATA drives each have their own cable that connects to the computer’s

motherboard. IDE drives share a single cable. When two drives share one cable,

you give them different names. IDE drives, those names are “Master” and “Slave.”

1. Find the drive’s Master/Slave identification chart usually printed in black on a

sticker attached to your drive.

2. If your drive doesn’t have a sticker, visit the drive manufacturer’s Web site and

downloads the pin settings.

3. Locate the drive’s Master/Slave pins.

These both live near where the data and power cables plug into the drive.

You’ll find six or more pins, but they’re always set in pairs like the ones in the

photo.

4. With a pair of tweezers or needle-nose pliers, place the jumper (a little plastic

thingy) across the correct pair of pins, either Master or Slave.

Ex.No.8: TO Assembling and Disassembling of Laptop to identify the parts and to

install OS and configure it.

Aim:

To configure Assembling and Disassembling of Laptop to identify the parts and to install

OS and configure it.

Procedure:

Laptop assembly Guidelines

There are several types of small screws that are used throughout the laptop. Place

these in small envelopes and write the component name on the envelope. Be organized

and keep track of all the screws.

We have to figure out how to remove the back panel.

The first component to install is the processor. Take extreme care not to touch the pins

in the socket during the process.

For wireless connectivity, our system uses a Mini-

PCIe slot rather than the more common Mini-PCI


69

variety. Be sure to connect the wires first before sliding the card into the slot.

Most barebones notebooks use upgradable MXM graphics cards, which can be difficult to

find at stores but are easy to install. Gamers should go with the most powerful MXM

card available.

Pop in the video card:

To install the MXM graphics card, first find the baggie with three larger silver screws and

two small black screws. Hold the card at about a 30-degree angle as you insert its edge

connector into the video-card slot near the center of the motherboard. Press the card in and

downward, and then use the two small black screws to secure it in place.

Set up the drive:

The motherboard SATA connectors are along the front, right edge, under the lip of the

laptop's shell. Drop the drive into place and then carefully use your thumb to push the drive

into the SATA connectors. Now use the remaining two screws to secure the drive in place.

Add memory:

The last internal components to install are the SO-DIMM memory boards. The two

memory slots sit between the graphics card and the large silver finned heat sink, near the

center of the motherboard.

Final assembly:

Now that all the hardware components are installed, find the four screws you removed

from the ACE Door, slide the door back into place, and replace the screws. To prepare for

power up, pop in the notebook's battery pack, connect the power brick, and plug it into a

wall outlet. Finally, open the laptop's cover, cross your fingers on one hand, and use your

other hand to press the power button.

LAPTOP DISASSEMBLY GUIDELINES

You will also need a mini Phillips screwdriver, anti-static wrist strap, magnifying glass, and

good lighting.

Wireless LAN Module:

The WLAN Module is consistently located on the back of the laptop

The RTC Battery:

The RTC Battery (Real Time Clock) can be located in the memory module, hard drive,

WLAN, or any compartment in the back of the laptop. The HP dv4000 locates the RTC in the

Mini PCI compartment as shown below.

Switchboard and Keyboard Removal:

To access many laptop components the keyboard must be removed. Often, the

switchboard, keyboard cover, and other components must be removed to access the keyboard

connections and screws. The HP ze5300 is a good example below.


72

CD/DVD Drive removal (Optical Drive):

Display Assembly Removal”

Removing the Display Assembly is one of the more intricate procedures when working

on a laptop. The HP dv2700 requires the removal of many components beginning with the

Wireless Antenna Cable located in the WLAN module compartment and also a screw

that secures the Display Assembly to the computer.

The Keyboard and Switch cover also need to be removed. Follow the illustrations

below to get an idea of the procedure.

Procedure:

Configure Internet connection and use IPCONFIG, PING:

1. Open Command Prompt, and then type ipconfig. From the display of the ipconfig

command, ensure that the network adapter for the TCP/IP configuration you are testing

is not in a Media disconnected state.

2. At the command prompt, ping the loopback address by typing ping 127.0.0.1.

3. Ping the IP address of the computer.

4. Ping the IP address of the default gateway.

If the ping command fails, verify that the default gateway IP address is correct

and that the gateway (router) is operational.

5. Ping the IP address of a remote host (a host that is on a different subnet).

If the ping command fails, verify that the remote host IP address is correct, that the

remote host is operational, and that all of the gateways (routers) between this computer

and the remote host are operational.

6. Ping the IP address of the DNS server.

If the ping command fails, verify that the DNS server IP address is correct, that the

DNS server is operational, and that all of the gateways (routers) between this computer

Tracer network:

Open Command Prompt, and type the following:

tracert host_name

ms-its:C:/WINDOWS/Help/tcpip.chm::/EXEC=,cmd.exe,,%20CHM=ntshared.chm%20FILE=alt_url_windows_component.htm


ms-its:C:/WINDOWS/Help/tcpip.chm::/HELP=glossary.hlp%20TOPIC=ip_address_def

ms-its:C:/WINDOWS/Help/tcpip.chm::/HELP=glossary.hlp%20TOPIC=GLS_DNS_SERVERS



85

Or, type tracert ip_address

where host_name or ip_address is the host name or IP address, respectively, of the

remote computer.

For example, to trace a connection route from this computer to www.microsoft.com,

type the following at a command prompt:

tracert www.microsoft.com

If you do not want the tracert command to resolve and display the names of all routers

in the path, use the -d parameter. This expedites the display of the path. For example,

to trace a path from this computer to www.microsoft.com without displaying the router

names, type the following at a command prompt:

Net stat utilities to debug the network issues:

Displays active TCP connections, ports on which the computer is listening, Ethernet

statistics, the IP routing table, IPv4 statistics (for the IP, ICMP, TCP, and UDP protocols), and

IPv6 statistics (for the IPv6, ICMPv6, TCP over IPv6, and UDP over IPv6 protocols). Used

without parameters, netstat displays active TCP connections.

Syntax

netstat [-a] [-e] [-n] [-o] [-p Protocol] [-r] [-s] [Interval]

Parameters

-a

Displays all active TCP connections and the TCP and UDP ports on which the computer is

listening.

-e

Displays Ethernet statistics, such as the number of bytes and packets sent and received. This

parameter can be combined with -s.

-n

ms-its:C:/WINDOWS/Help/tcpip.chm::/HELP=glossary.hlp%20TOPIC=ip_address_def


86

Displays active TCP connections, however, addresses and port numbers are

expressed numerically and no attempt is made to determine names.

-o

Displays active TCP connections and includes the process ID (PID) for each connection. You

can find the application based on the PID on the Processes tab in Windows Task Manager.

This parameter can be combined with -a, -n, and -p.

-p Protocol

Shows connections for the protocol specified by Protocol. In this case, the Protocol can be tcp,

udp, tcpv6, or udpv6. If this parameter is used with -s to display statistics by protocol,

Protocol can be tcp, udp, icmp, ip, tcpv6, udpv6, icmpv6, or ipv6.

-s

Displays statistics by protocol. By default, statistics are shown for the TCP, UDP, ICMP, and IP

protocols. If the IPv6 protocol for Windows XP is installed, statistics are shown for the TCP over

IPv6, UDP over IPv6, ICMPv6, and IPv6 protocols. The -p parameter can be used to specify a

set of protocols.

-r

Displays the contents of the IP routing table. This is equivalent to the route print command.

Interval

15. Click Finish after the configuration process is completed.

Connecting the hardware and cables:

When setting up your network hardware and cables, keep the following in mind:

All PCs must have networking hardware already installed. Examine the back of the PC

for an RJ45 port (it looks like a port for a typical phone but is wider with eight contacts).

If you have more than two PCs, you will need at least one multi-port sharing device like

a hub, switch, or router with enough ports to support all your PCs.

If you are only networking two PCs, all you need is one crossover cable. You do not need

a hub, switch, or router.

Multi-port sharing devices that work for creating small networks:

Hubs are usually the least expensive of the devices. Hubs simply repeat the data

flow out to the other lines. These work good in small networks.

Switches are like hubs but filter IP addresses to increase data flow in larger

networks.

Routers become necessary when networking over 254 computers. A router can

also be used to share one IP address with several other PCs (not discussed in this

document).

The network link between PCs can only be as fast as the slowest device in the link. Try

to use all networking devices with the same speed rating for optimal performance (this

include cables).

Try to keep hubs, switches, and routers accessible.


92

Some hubs, switches, and routers, require the last port be used only when the cascade

port is not already in use. Do not connect a network cable for a PC into the cascade port

unless you are "cascading" to another device.
