Lab Session-1
Introduction to Computer System components and BIOS
This lab session deals with:



Opening up of computer system, disassembling the various parts inside the computer,
understanding the functionality of each and assembling them back.
Opening up of hard disk and CDROMS and understanding their working mechanism
Doing some specific tasks using BIOS
This manual covers the steps which you might like to follow while doing these tasks.
Disassembling and Assembling Computer System Components:
You’ll be provided a tool box containing screw drivers of various sizes.
You will be opening up the computer system provided to you and examining various
components inside the computer. Here are the diagrams that give a good view of the various
components that you will be examining.

You are required to know the basic functionality of these components (Google, Wikipedia are
your best friends!)
Opening up Hard disks and CDROMS:
In a group of 6, you would be opening up hard disks and CDROMS provided to you. You’ll be
examining the parts and features of hard disks and CDROMS as described below.

The Parts and the functions of the CD-ROM DRIVE are as follows:
1. Drawer - for loading the media.
2. Metal Case - covering the CD-ROM from dust and for packaging.
3. Clipsed Compounds - For connecting the internal devices
4. Sinple Jack - connects electric devices together within the CD-ROM
5. Belt - Controls the drawer in & out of the CD-ROM
6. Focus lense - reads the input media
7. Electric motor - controls the drawer
8. Connection cables
9. Electric Circuit - Supplies current to other electrical parts.

conventional screwdrivers.
Carefully separate the circuit board from the hard disk, and pull out the cables. The
cables are locked in place, so you may have press the slot on the sides to unlock the
cables.
Remove all the stickers and tapes covering the hard disk. There will be some screws
hidden under a few warranty stickers, and a tape around the disk, protected by the
warranty sticker.
Remove all the screws that are still there.
Carefully open the case. Try pulling the upper and the lower parts of the disk. If that
doesn’t open it, check if there are any screws still screwed in. Otherwise, use a flat-head
screwdriver to pry it open.
Remove all the visible screws.
Carefully remove the actuator and its arm from the chassis. Ensure that you do not
damage the head. You may remove the spindle and the platters at the same time to
ensure that the actuator arm isn’t damaged.
