Learn to troubleshoot laptops that won’t turn on by measuring voltages with a multimeter, tracing control signals, and identifying faulty MOSFETs, diodes, and coils on the motherboard.
Learn a practical, step-by-step approach to troubleshoot, diagnose, track, and repair two different laptops, including hands-on disassembly and assembly across models, with fundamentals of motherboard circuits and components.
Diagnose laptop power issues by testing the power adapter and battery, verifying connections, and following step by step troubleshooting from opening the case to motherboard diagnosis.
Master laptop disassembly to troubleshoot and diagnose hardware issues, removing ram, battery, hard drive, optical drive, keyboard, screen, and ultimately the motherboard while disconnecting all connectors.
Assess power jack cable serviceability by inspecting four-wire power track, testing continuity across red positive and black negative leads, and confirming the cable and adapter output before diagnosing the motherboard.
Explore motherboard circuits and power management basics, including mosfets, capacitors, inductors, and dual voltage rails, then perform visual inspection and proper heatsink removal to diagnose a failed laptop motherboard.
Disassemble and inspect the motherboard, identifying the processor, RAM slots, heatsink, and chipset, then locate MOSFETs, capacitors, inductors, CMOS battery, and BIOS, and test continuity and voltages.
Explore hands-on troubleshooting of a laptop motherboard power circuit by tracing 20-volt rails, validating MOSFET control signals, and replacing a faulty MOSFET to restore power distribution.
Learn to desolder a failed MOSFET with hot air, remove it with tweezers, apply a small amount of solder paste, and install a new MOSFET aligned with the marks.
