Tips you should keep in mind before beginning work inside a computer case REF. PAGE: 46

What is the first step you should perform before working inside the case of a working computer?

Back up important data. REF. PAGE: 47

What should you do after you unplug the computer to be sure the power supply is completely drained?

Press and hold down the power button for a moment. REF. PAGE: 47

Why are motherboards installed in the case using spacers?

A motherboard is installed so that the bottom of the board does not touch the case. If the fine traces or lines on the bottom of the board were to touch the case, a short would result when the system is running. To keep the board from touching the case, spacers or standoffs may be used. REF. PAGE: 55-56

List and describe the five front panel connectors you will likely see going from the front panel to the motherboard.

– Power SW. Controls power to the motherboard; must be connected for the PC to power up – HDD LED. Controls the drive activity light on the front panel that lights up when any SATA or IDE device is in use (HDD stands for hard disk drive; LED stands for light-emitting diode) – Power LED+. Positive LED controls the power light and indicates that power is on – Power LED-. Negative LED controls the power light; the two positive and negative leads indicate that power is on – Reset SW. Switch used to reboot the computer REF. PAGE: 64

Describe the processor cooler and its components.

The cooler sits on top of the processor and consists of a fan and a heat sink. A heat sink uses fins that draw heat away from the processor. The fan can then blow the heat away. REF. PAGE: 67

How does liquid cooling work?

Using liquid cooling, a small pump sits inside the computer case, and tubes move liquid around components and then away from them to a place where fans can cool the liquid, similar to how a car radiator works. REF. PAGE: 71

What are two major points you should keep in mind when selecting the correct wattage capacity for a power supply?

Video cards draw the most power. Video cards draw the most power in a system, and they draw from the +12 V output. If your system has a video card, pay particular attention to the +12 V rating. The trend nowadays is for the motherboard to provide the video components and video port, thus reducing the overall wattage needs for a system. The power supply should be rated about 30 percent higher than expected needs. Power supplies that run at less than peak performance last longer and don’t overheat. In addition, a power supply loses some of its capacity over time. Also, don’t worry about a higher rated power supply using too much electricity. Components only draw what they need. REF. PAGE: 75
