  2. 2. Outline <ul><li>Introduction & Equipment </li></ul><ul><li>Warnings </li></ul><ul><li>Steps 1 & 2: Prep work </li></ul><ul><li>Step 3: Remove and Label Components </li></ul><ul><li>Step 4: Rebuild </li></ul><ul><li>Steps 5 & 6: Plug in and Reboot </li></ul><ul><li>Wrap-Up </li></ul>
  3. 3. Introduction <ul><li>Why have your students disassemble and reassemble a computer? </li></ul><ul><ul><li>Get over the fear of what’s inside </li></ul></ul><ul><ul><li>Develop a better understanding of what makes up a computer </li></ul></ul><ul><ul><li>Build confidence </li></ul></ul><ul><ul><li>Mostly: BECAUSE IT’S FUN! </li></ul></ul>
  4. 4. Equipment <ul><li>Screwdriver </li></ul><ul><li>A computer (these are old Pentiums donated by the UW Library) </li></ul><ul><li>Monitor and keyboard (no mouse) </li></ul><ul><li>Small post-it notes </li></ul><ul><li>Anti-static bracelets/mats </li></ul><ul><li>Handout </li></ul>
  5. 5. Warnings <ul><li>Disassembly: UNPLUG from wall first </li></ul><ul><li>After reassembling, screw the lids onto the boxes before powering up (the wires from the power button to the power supply are live, so you don’t want to be near them when the computer is on) </li></ul><ul><li>Rebooting: plug into the wall LAST </li></ul>
  6. 6. Warnings (cont’d) <ul><li>Make sure the room you use has enough power (separate circuits) </li></ul><ul><li>Be careful - computers have sharp parts inside (we have band-aids) </li></ul><ul><li>Decide how much to have the students remove, given time constraints, etc. </li></ul>
  7. 7. Step 1 – Getting Ready <ul><li>Have computers booted up when students come in, so they see that they work (no Windows installed on these - just DOS) </li></ul><ul><li>Shut down computers </li></ul><ul><li>Put on anti-static bands and clip them to grounding mats </li></ul><ul><li>Read over handout </li></ul>
  8. 8. Step 2 – Looking Inside <ul><li>UNPLUG all cables </li></ul><ul><li>Remove cover </li></ul><ul><ul><li>Unscrew 4 screws at back closest to the edge of the computer, then pull the sides of the computer forward </li></ul></ul><ul><ul><li>The front and side panels slide off the front all in one piece </li></ul></ul><ul><li>Lay the computer on it’s side with the motherboard closest to table surface </li></ul>
  9. 9. Back of Computer Remove these screws

  13. 13. What these components do <ul><li>RAM – Random Access Memory – (short-term memory) holds data and program instructions that the computer is currently using </li></ul><ul><li>Floppy and CD-ROM drives – (mouth/ears) allow you to give data to the computer and take data away from the computer </li></ul><ul><li>Power Supply – (heart) supplies power to all </li></ul><ul><li>Network Card – (telephone) allows computer to talk to other computers over a wire </li></ul>
  14. 14. What these components do <ul><li>Video card – (face) Does all of the processing necessary to get stuff looking nice on screen, quickly </li></ul><ul><li>Sound card – (vocal cords) Allows sounds from HD or CD-ROM to be displayed </li></ul><ul><li>Card Slots – (hands) Allows other components to be added to the computer (joystick cards, tv cards, etc.) </li></ul>
  15. 15. Step 2 (cont’d) <ul><li>The handout has a listing of the parts to be disassembled: </li></ul><ul><ul><li>CD-ROM drive, sound cable, ribbon cable (unplug power) </li></ul></ul><ul><ul><li>Floppy drive, ribbon cable (unplug power) </li></ul></ul><ul><ul><li>Sound, Video and Network cards </li></ul></ul><ul><ul><li>Memory </li></ul></ul><ul><li>Draw the component beside each name on the handout </li></ul>
