Study Notes

Connecting Cables to Computer

Connect the power supply cable into the back of the computer case.
Attach peripheral devices such as printers, scanners, and webcams to the computer.

Starting the Computer

Ensure the power button on the CPU is pressed before the monitor.
The operating system (Windows or Linux) will load, preparing the computer for use.

Computer Disassembly Overview

Disassembly involves breaking down a PC into its individual parts.
Required materials: working PC, anti-static wrist strap, anti-static mat, anti-static bags, technician's toolkit, container for screws.

Steps for Computer Disassembly

Unplugging: Disconnect the power cord and all peripherals (keyboard, mouse, monitor, headphones).
Open the Case: Remove screws from the left side cover and slide it off.
Disconnect Connectors: Unplug all connectors from the motherboard, including SATA power and data cables for HDD and optical drives.
Remove Fan: Detach the cooling fan from the case.
Remove Power Supply: Disconnect the power supply, which has 20-pin and 4-pin connectors to the motherboard.
Remove HDD and Optical Drive: Unplug SATA cables connecting these drives to the motherboard.

Computer Assembly Overview

Assembly is critical for computer installation and functionality.
Proper sequence and organization of each component are necessary for a successful assembly.

Steps for Computer Assembly

Open the Case: Remove screws and slide off the left side panel.
Install Power Supply: Secure the power supply with screws into the case.
Attach Components to Motherboard: Install CPU, apply thermal compound, and attach heat sink and fan assembly.
Install RAM: Ensure RAM compatibility with the motherboard before installing.
Install Motherboard: Place the prepared motherboard in the case.
Install Internal Drives: Connect power cable from the power supply to the hard drive and attach SATA data cable from the hard drive to the motherboard.
Connect Internal Cables: Use power cables to distribute electricity and data cables for data transmission between components.
Install Motherboard Power Connections: Connect the ATX main power connector, which may have either 20 or 24 pins.
Connect External Cables:
