Lab #12 Help Document
This help document will be structured as a walk-through of the lab. We will include instructions about how to write the report throughout this help document.
This lab will be completed in room 335 CTB.
You will need to partner up for this lab in groups of two.
This lab will require the use of the following piece of equipment:
Old computer
Procedure
1. Define the following words: CPU- I/O- Memory- BIOS- RAM-ROM-Power Supply-Motherboard-Monitor-Keyboard-
This is pretty self-explanatory. If you have your book, you can use that. You can also use Google’s define function where you type:
Define: word to be defined
in the search box. Make sure you choose a definition that is relevant to computers if you do this. There are other resources and online dictionaries that you can reference as well. As with Google, make sure that the
definition you choose is relevant to computers.
For your lab report: Include these words and their appropriate definitions.
2. You will be given a working computer. Turn it on and verify that it works. Then shut it down properly, unplug it, and take the computer part of it completely apart. The parts you should remove are the DIMMs, the DVD-ROM drive, the Hard Drive, and the power supply. Carefully document what you do as you do it.
Please read this section completely before beginning.
When removing a cable of any sort, always grab the plug. NEVER grab the wires and pull to remove a cable!DO NOT touch the pin connections for the DRAM memory chip! This can ruin the component by making it so that it doesn’t connect completely to the motherboard.
Since for this lab you need to document what you do as you go, we won’t provide a step-by-step explanation of what you do. We will include tips and hints to help you as you go to help you with removing and reattaching parts that are not as obvious or that are delicate.We recommend that you remove the components in this order:
Power supply
DVD-ROM Drive
Hard Drive
DRAM memory
By extension, we recommend that you reinstall the components in the reverse order, so:
DRAM memory Hard DriveDVD-ROM DrivePower supply
The first step is to remove the case cover so that you can get into the computer. To do this, press the buttons on the left and right sides of the computer and pulled forward. You will likely need to press these with some force to get it to release. Once it has released the cover, pull forward then lift it up and remove it so that you can see the internal components of the PC.
To remove the power supply, simply lift and swing it out.
It is only necessary to disconnect the power supply from the parts of the computer that you are removing or swinging out. Leaving other connections in (for instance the 24 pin connection that connects to the motherboard) is fine if you leave it connected. The 4-pin connections leading to the DVD-ROM drive and the SATA power cable to the hard drive, however will need to be removed.
The thin wide ribbon cable (also known as an IDE cable) can be a bit of a pain to reconnect. It only has a certain number of connections and their spacing is such that each connection must go with the component it is connected to. It is also keyed, meaning that you can’t plug it in if the connector is upside-down.
The small blue cable (known as a SATA cable) is connected to the Hard Drive. This cable is easily removed. It too is keyed to only be inserted one way.
The 4-pin and SATA power connecters are also keyed so that they cannot be plugged in upside down. They all provide the same voltage to components, so it doesn’t matter which one goes to which component beyond the fact that they are not all the same length. Longer cables should be used to connect to components that are further away from the power supply. Removing these cables can be a little tricky. They are designed not to come out easily, so you may have to wiggle and pull on them a bit to remove them.
To remove the DVD drive, press down the green tab on the front and pull it forward and then up.
To remove the Hard Drive press the green tab away from the Hard Drive and pull the Hard Drive forward and up.
To remove the memory, push the two tabs on the side of each stick down first before pulling out the card. To reinsert it, you would push the card in firmly until it “pops” back in and then close the side clamps on it. It should not move around when shaken after being reinstalled.
For your lab report: Include a step-by-step process of how you disassembled the computer. You will need to
include enough detail so that you can reassemble the computer and so that another individual could take it apart properly. Pictures are welcome if you believe that they would help with the description, but the description must still make sense to the reader and be complete.
3. Now put it all back together and test for proper operation. Record anything you did wrong, so you won’t do it wrong the next time.
When reassembling everything, make sure that the cables are completely pressed back into their respective connections. Also make sure that the memory is completely connected (it should not move when wiggled if it is connected properly).
This is pretty self-explanatory. Simply reassemble the computer in the reverse order that you took it apart. Make sure to connect everything back properly or it may not work.
Once you have completed your reassembly, bring your computer to the TA present, connect it to the monitor and power strip provided, and turn on the computer. If it turns on and boots up, congratulations, you’ve successfully reassembled a computer. If not, you will need to open it up again and see what you did wrong.
For your lab report: Include a step-by-step process of how you reassembled the computer. You will need to include enough detail so that another individual could properly reassemble the computer. Pictures are welcome if you believe that they would help with the description, but the description must still make sense to the reader and be complete. Also include any mistakes you made in the reassembly.
Report and Conclusion
Write a general conclusion about the process of assembling a computer and any other things you may have observed.
