Overview
This lesson introduces common tools and equipment used in computer system servicing, focusing on their identification, safe handling, and roles in ICT work.
Learning Objectives
- Identify various ICT tools and equipment and their purposes.
- Gain hands-on experience with ICT tools, emphasizing safety and correct operation.
- Appreciate how ICT enhances efficiency and problem-solving.
Hand Tools
- Phillips and flathead screwdrivers are used to remove and secure screws in computer components.
- Torx screwdrivers fit star-shaped screws found in some laptops and electronics.
- Tweezers help pick up small parts or connectors in tight spaces.
- Longnose pliers reach narrow spaces and bend wires; side cutting pliers cut wires and cable ties.
- An anti-static wrist strap prevents electrostatic discharge (ESD) damage to sensitive components.
- Hex keys (Allen wrenches) and nut drivers tighten or loosen hexagonal bolts found in cases and racks.
Testing and Diagnostic Tools
- Multimeters measure voltage, current, and resistance to diagnose power and circuit problems.
- LAN cable testers check the integrity and wiring of network cables.
- POST (Power On Self-Test) diagnostic cards detect hardware issues by displaying error codes during boot.
Cleaning Tools
- Soft brushes remove dust from delicate components.
- Compressed air cans blow out dust from keyboards, power supplies, and cases.
- Isopropyl alcohol cleans thermal paste and grime; evaporates quickly and leaves no residue.
- Lint-free or microfiber cloths clean screens and delicate surfaces without scratching.
Computer Equipment and Accessories
- External hard drives or flash drives help with backups and data transfers during servicing.
- Bootable USB drives contain operating systems or diagnostic utilities for troubleshooting.
- Spare components like RAM, power supplies, and cables are used for part swapping to confirm faults.
Organizational Aids
- Cable ties or Velcro straps manage cables inside cases to improve airflow and reduce clutter.
- Toolboxes keep tools organized, safe, and portable.
- Thermal paste is applied between the CPU and heat sink to improve heat transfer and prevent overheating.
Key Terms & Definitions
- ESD (Electrostatic Discharge) — the sudden flow of electricity between two electrically charged objects.
- Multimeter — a device that measures electrical properties such as voltage, current, and resistance.
- POST Card — a diagnostic card that displays error codes during computer startup to identify hardware issues.
- Thermal Paste — a substance that improves heat conduction between a CPU and heat sink.
Action Items / Next Steps
- Practice handling and identifying the tools discussed.
- Review manufacturer guidelines on safe tool use.
- Prepare for a practical session on ICT equipment handling.
