Lab Exercise 205: Disassembling the System Unit and Identifying Internal Components and Connections
Look inside your system case What do you see To begin with, you ll see lots of cables and wires Some appear to be single-colored wires, while others seem to be multiple gray-colored wires in the shape of wide ribbons Most colored wires originate at the power supply and end at the various devices to supply the needed direct current (DC) power to run the PC The wide ribbon cables attach at various points and are used to transfer data These are sometimes referred to as logic cables or data cables See if you can locate in your system case the major components labeled in Figure 2-8 You may have to move some of the fan shrouds, wires, and cables in order to nd them, especially components on the motherboard but remember your anti-static procedures and be gentle Sometimes the slightest bump is enough to unseat a connection Step 3 Now it s time to take some notes, draw some sketches, or take a few pictures Before you start disassembling this machine, document where the components belong and what wires and cables are connected to the different components Be prepared to take a few notes on how you actually removed the component (this will really help when you go to reinstall the components) Include as much detail as possible; it will only help in getting the system unit back together Step 4 To start, you ll need to clear the way a bit like peeling an onion, layer by layer by removing the easily accessible components and cables rst

2: The Visible PC
Look inside the PC and nd the expansion slots How many total expansion cards can be plugged into your system ______________ Some of the expansion slots may have cards in them These may be modem cards, sound cards, network cards, or video cards Since expansion cards are designed to expand the capability of the computer system, they are designed to be installed after the system unit is assembled For this reason, the expansion cards are a great place to begin your disassembly Look at the expansion cards installed in your PC, and then look at the external connectors on each Can you match the cable to the expansion card Remove all installed expansion cards from your system unit Place each card into an anti-static bag to protect it from ESD damage Step 5 If the machine you are disassembling is only a few years old, it will probably have multiple fan shrouds to make sure the air ow is getting to the main components to keep them cool Remove any fan shrouds from your system unit and place them out of the way on your workspace
