Introduces isopropyl alcohol, flux, thermal paste, and adhesive strips used in laptop repair. Safe handling of chemicals protects both technician and components.

Lesson 3 • Workbench Organisation and Workflow

Defines a logical bench layout, part labelling, and documentation habits. Organised workflow reduces errors and speeds up multi-step repairs.

Lesson 4 • Essential Hand Tools for Laptop Repair

Introduces screwdrivers, spudgers, pry tools, and tweezers specific to laptop work. Correct tool selection prevents cosmetic and structural damage during repair.

Lesson 1 • Cooling System Components

Describes heat pipes, fans, and thermal pads as a unified thermal management system. Understanding cooling prevents misdiagnosis of heat-related failures.

Lesson 2 • Motherboard Architecture Basics

Explains chipset layout, power rails, and bus connections on a laptop motherboard. Provides the circuit-level map students reference throughout the course.

Lesson 3 • Display and Input Hardware

Covers LCD, OLED, and touchscreen panel types alongside keyboard and trackpad hardware. Grounds students in the user-facing components they will frequently service.

Lesson 4 • Laptop Form Factors and Design

Covers clamshell, 2-in-1, and ultrabook designs and how form factor affects repairability. Sets the physical context for all disassembly work ahead.

Lesson 1 • Reassembly Quality Checks

Establishes a post-reassembly checklist covering screws, connectors, and boot verification. Systematic checks catch errors before the device reaches the customer.

Lesson 2 • Removing and Replacing Key Components

Guides removal and reinstallation of RAM, storage, battery, and Wi-Fi cards. Correct handling and seating of each part ensures reliable post-repair operation.

Lesson 3 • Bottom Cover Removal Techniques

Covers screw patterns, hidden clips, and pry sequences for safe bottom cover removal. This is the entry point for all internal component access.

Lesson 4 • Reading Service Manuals and Schematics

Teaches how to locate, read, and apply official service documentation before touching a device. Documentation-first habits prevent avoidable damage and wasted time.

Lesson 1 • DC Jack Replacement and Repair

Covers desoldering, pad repair, and resoldering of DC power jacks on motherboards. Jack replacement is one of the highest-frequency physical repairs in the field.

Lesson 2 • AC Adapter and DC Jack Fundamentals

Explains adapter voltage and current ratings, barrel jack types, and USB-C PD delivery. Adapter and jack faults are the most common power entry failures.

Lesson 3 • System Power Rails and Sequencing

Maps the voltage rails generated by the power management IC and their sequencing order. Rail faults cause no-boot conditions diagnosed in the next chapter.

Lesson 4 • Battery Technology and Management

Covers Li-ion and Li-polymer cell chemistry, BMS operation, and charge cycle limits. Battery knowledge underpins safe replacement and charge fault diagnosis.

Lesson 1 • BGA Chip Reballing and Replacement

Introduces BGA removal, reballing, and reflow for GPU, CPU, and bridge chips. BGA work is the most advanced soldering skill in laptop board repair.

Lesson 2 • Hand Soldering Fundamentals

Teaches wetting, heat transfer, and solder flow for through-hole and SMD joints. Solid hand-soldering technique is the foundation for all board-level repair.

Lesson 3 • Hot-Air Rework for SMD Components

Covers preheat, airflow, and temperature control for removing and placing SMD parts. Hot-air rework enables connector, capacitor, and IC replacement on thin boards.

Lesson 4 • Board Cleaning and Post-Solder Inspection

Details flux residue removal, visual inspection, and electrical verification after rework. Clean boards and verified joints prevent latent failures after repair.

Lesson 1 • No-Power and No-Boot Diagnosis

Diagnoses dead-laptop scenarios by testing power rails, POST codes, and boot signals. Builds directly on power rail knowledge from the previous chapter.

Lesson 2 • Display and GPU Fault Diagnosis

Isolates blank screen, flickering, and artifact faults to panel, cable, or GPU source. External monitor testing is the key pivot point in display diagnosis.

Lesson 3 • Structured Diagnostic Methodology

Introduces symptom-to-cause logic trees and the divide-and-conquer isolation strategy. A repeatable method prevents guesswork and reduces unnecessary part replacements.

Lesson 4 • Connectivity and Peripheral Fault Diagnosis

Diagnoses Wi-Fi, Bluetooth, USB, and audio failures using device manager data and hardware tests. Peripheral faults often stem from driver, firmware, or physical connector issues.

Lesson 1 • Data Backup and Recovery Techniques

Uses live boot environments and recovery tools to extract data from failing drives. Data recovery skills protect customer files before destructive repair steps.

Lesson 2 • BIOS and UEFI Fundamentals

Explains BIOS/UEFI roles, settings navigation, and boot order configuration. Firmware knowledge is prerequisite for flash recovery and boot fault resolution.

Lesson 3 • Driver and Firmware Update Management

Manages driver conflicts, rollbacks, and firmware updates for stable system operation. Proper update management prevents recurring post-repair failures.

Lesson 4 • Operating System Reinstallation

Guides bootable media creation, partition setup, and clean OS installation. Reinstallation resolves corruption, malware, and driver conflicts beyond repair.

Lesson 1 • Power Management IC Diagnosis and Repair

Diagnoses failed PMICs and voltage regulators causing missing or unstable power rails. PMIC faults are among the most common causes of no-boot motherboard failures.

Lesson 2 • Liquid Damage Assessment and Repair

Covers corrosion mapping, component triage, and board cleaning after liquid intrusion. Liquid damage repair requires combining all prior diagnostic and soldering skills.

Lesson 3 • Short-Circuit Isolation Techniques

Uses thermal imaging, current injection, and resistance mapping to locate board shorts. Short isolation prevents repeated component failures after initial repair.

Lesson 4 • Embedded Controller Fault Diagnosis

Identifies EC firmware corruption and hardware faults causing keyboard, power, and fan failures. EC issues are frequently misdiagnosed as motherboard or OS problems.
