Study Notes

PC Disassembly and Assembly Procedures

  • Disassembly is prioritized over assembly in training because servicing involves more disassembly than new builds. Focus on system unit servicing.
  • Disassembly Preparation: Unplug the system unit, wear an antistatic wrist strap, use an antistatic mat, and ensure a large, flat work surface.

Disassembly Checklist

  • System Unit Unplug: Verify unplugging before disassembly.
  • PPE (Personal Protective Equipment): Correctly wear anti-static wrist strap.
  • Component Removal: Safely and correctly remove: outer casing, case fan, CPU fan, power supply, RAM, optical drive, hard drive, and motherboard.

Assembly Preparation

  • Cleaning: Clean all equipment and parts before assembly.
  • Prevent CPU Exposure: Prevent prolonged exposure of the CPU.
  • Thermal Paste: Prepare to reapply thermal paste.
  • PPE (Personal Protective Equipment): Must wear anti-static wrist strap for assembly.

Assembly Checklist

  • Equipment Cleaning: Clean equipment and parts before assembly.
  • PPE (Personal Protective Equipment): Wear anti-static wrist strap.
  • Component Installation: Carefully and correctly install: CPU fan, hard drive, optical drive, RAM, power supply, interface cards, and system fans.
  • Cover Attachment: Securely attach the system cover.

I/O Device Installation

  • Install Keyboard/Mouse: Install keyboard (USB or PS/2) and mouse (USB or PS/2) first, then install operating system.
  • Keyboard: Read the keyboard instruction manual, identify connector type (USB or PS/2), and connect to the correct port.
  • Mouse: Similar procedure to keyboard installation. Follow device instructions.
  • Monitor: Connect monitor to motherboard or graphics card using DVI, VGA, or HDMI. Drivers may be required for optimal resolution.
  • Speakers: Connect speaker cable to computer sound card line-out jack (usually 3.5mm).
  • Webcam: Commonly plug into USB port; may require driver installation (refer to user manual).
  • Printer: Connect printer cable, install ink/toner, turn on printer and computer, run printer setup wizard, and check test print.
