2 sections • 17 lectures • 1h 29m total length

Introduction4:08
Understand MOSFET circuitry, drain and ground connections, and 3.3V/5V rails with capacitors and filters. Learn the professional step-by-step process to diagnose, isolate, and repair inoperative laptop motherboards.

visual inspection2:34
Diagnose a laptop motherboard through a thorough visual inspection. Check RAM installation, the processor, graphics card, and other components for abnormalities, then inspect both sides and all connectors, including RJ-45 and SATA.
Motherboard Main Power Diagnosis2:01
practice diagnosing the motherboard main power by connecting the adapter, using a multimeter to measure the supply, selecting a 20-volt setting, and grounding the probes to verify a 19-volt output.
Central Processing Unit Circuit Diagnosis4:34
Learn how to diagnose a laptop motherboard cpu circuit by tracing voltage rails, identifying faults with resistors and capacitors, and analyzing power management circuits across channels.
Drawing and analysis of CPU circuit diagram part 14:21
Analyze a cpu circuit diagram by identifying mosfets, capacitors, gates, and ground connections, and explain power arrangements and signal driving for a laptop motherboard.
Drawing and analysis of CPU circuit diagram part 24:45
Examine the cpu circuit diagram through polarized capacitors and mosfets, detailing gate drive high, drain, and ground connections across two channels and how power distributes from the supply.
Motherboard Power Rail Analysis3:48
Diagnose laptop motherboard power rails by tracing the 19 volt supply from the adapter through switches and mosfets into circuits powered by the power management unit.
3V & 5V Power Rail Schematic Analysis2:35
Analyze the 3v and 5v power rail schematic, tracing how capacitors, including ceramic ones, filter, how gates connect to ground, and how the laptop motherboard power system drives signals.
3V & 5V Power Circuit Analysis6:51
Diagnose a laptop motherboard's 3.3v and 5v power circuit by tracing the IOC-controlled MOSFET, using continuity checks, and referencing the Maxim 8744/8745 power controller and pin configurations.
3V and 5V Power Management IC Circuit Diagram Analysis Part 14:16
Analyze the power management IC circuit diagram, focusing on enable and shutdown signals, 5-volt and 3.3-volt generation, MOSFET drives, and the 19-volt input relationship.
3V and 5V Power Management IC Circuit Diagram Analysis Part 24:34
Analyze the 3V and 5V power management IC circuit diagram, tracing MOSFET gates and drive signals, feedback, and power-good outputs to understand laptop motherboard power regulation.
How to check 3V and 5V Power Management IC Pinout7:22
Diagnose the Maxim 8744 power management IC pinout to verify 3v and 5v rails, enable signals, and Vin on pin 21, using a multimeter.
3.3V Power Rail diagnosis and analysis5:09
Diagnose the 3.3v power rail on a laptop motherboard by inspecting MOSFET paths, checking voltages like 19v input, and tracing battery, IO, and power management connections.
Super IO CHIP Power Rail analysis5:04
Trace the 19V power rail through fuses and mosfets to feed the motherboard's 3.3V and 5V rails, powering the cpu, ram, bios chip, and keyboard circuits via the super io.
How to check Super IO IC4:51
Diagnose a laptop motherboard by inspecting the super io ic, test surrounding capacitors with a multimeter and buzzer, and decide whether to replace or reflash the bios.
CPU Power Management IC Analysis7:46
Learn to read and analyze cpu power management circuits on a laptop motherboard, using max 87 70 references to map input voltage to cpu core outputs via mosfets.
Conclusion14:31
Follow how the 19-volt input passes through MOSFETs, sense resistors, and filters to create CPU and RAM voltage rails. Recognize that all boards share the same power management channel architecture.
