1 TEE COURSE GRADE 10 Anatomy of a PC DISASSEMBLING AND REASSEMBLING STORAGE DEVICES Practical Activity Guidelines and steps

2 Learning Objectives At the end of this practical activity, you will: Answer to the expectations in Grade 10 Curriculum policy document regarding PC Harware Get over the fear of what’s inside of a computer and build confidence (especially girls). Develop a better understanding of what makes up a computer. Be able to uninstall, install and troubleshooting main storage devices: RAM, FDD, HD, CD-ROM, DVD. Develop your necessary skills to build a computer

3 Tools and Equipment you need Computers (these are old Pentiums) PPT Guidelines and steps Screwdrivers (the ones that are magnetized are great, but dangerous!) Small post-it notes

4 Warnings- Safety procedures Be careful - computers have sharp parts inside (we have band-aids). Don’t wear wool. Static electricity can damage memory. Keep distance if you have allergies to dust. Remove only: RAM, HD, Floppy Disk and CD-ROM. Each student has to remove or install at least a component.

5 Warnings – Safety procedures (cont’d) Don’t try to open the power supply! Tie back long hair. No graphite pencils. Be careful of dangly jewelry. Delicate equipment - don’t force it. Put screws back in holes.

6 Step 1 – Looking Inside Remove cover –Unscrew 4 screws at back closest to the edge of the computer, then pull the sides of the computer forward –The front and side panels slide off the front all in one piece Lay the computer on its side with the motherboard closest to table surface

7 Back of Computer Remove these screws

8 Step 2 – Looking Inside Identify all the major components: –Power Supply –Motherboard –Memory –Card Slots –Cards (sound, video, network) –CPU, heatsink and fan –Drives (floppy, hard and CD-ROM)

9 power supply hard drive motherboard COMPONENTS CD-ROM drive floppy drive cards

10 power supply hard drive RAM CPU and heatsink PCI and ISA card slots motherboard COMPONENTS drive housing

11 Step 3 – Taking it Apart Remove CD-ROM Drive –UNPLUG sound cable from CD –UNPLUG power cable from CD –UNPLUG ribbon cable from CD –Unplug other end of ribbon cable from motherboard, taking note of where it should plug back in, label with post-it –Unscrew CD-ROM drive and slide out –Label CD-ROM drive with a post-it note

12 CD-ROM Drive

13 Step 4 - Taking it Apart Remove Floppy Drive –UNPLUG power cable from floppy drive –UNPLUG ribbon cable from floppy drive Unplug other end of ribbon cable from motherboard and label it ‘floppy ribbon’ –Unscrew two screws at front –Pull floppy drive out –Unscrew floppy drive from tray

14 Floppy Drive

15 Step 5 – Taking it Apart Remove Hard Drive –UNPLUG power cable from HD –UNPLUG ribbon cable from HD Unplug other end of ribbon cable from motherboard and label it ‘HD ribbon’ –Unscrew hard drive and remove –Label hard drive with a post-it note

16 Hard Drive

17 Ribbon Cables polarized

18 Step 6 - Taking it Apart Remove ONE of the RAM cards (the one closest to the power supply) –RAM is held in place by clips at each end –To remove, pull and hold both clips away from the RAM, at this point, the RAM card should tilt to one side –Once RAM card is tilted to the side, it can slide out easily –Label RAM with Post-it

19 RAM

20 Look Inside Again! RAM BANK CPU, Fan, HeatsinkCard Slots (ISA & PCI)

21 Step 7 – Putting it Back Together Put it all back, reverse order (remove post-its as you re-assemble): Insert RAM card on an angle, then firmly push it into upright position RAM clips should snap into place Install FDD, HD, and CD (if the case)

22 Step 7 – (cont’d) Plug floppy ribbon cable into motherboard Slide floppy in and plug in power cable Plug ribbon cable into floppy (you should match the pink side of the ribbon cable to the end of the connector that has a ‘1’ label)

23 Step 7 – (cont’d) Plug ribbon cable for CD-ROM into the motherboard Slide CD-ROM back into case, replace screws, plug ribbon cable into CD (it only goes in one way) Plug power cable back into CD (it only goes in one way) Plug sound cable from sound card into the back of the CD-ROM drive
