Circuit Board & Solid-State Diagnostics

1. Short Circuit Isolation via Voltage Injection LAB BENCH POWER

Used to identify shorted multilayer ceramic capacitors (MLCCs) and compromised MOSFET switches pulling system rails to ground.

Protocol: Isolate primary power rail (e.g., PPBUS_G3H, 19V Primary). Set DC bench power supply explicitly below rail limit (1V–2V), limit current output to 1.5A. Inject voltage directly via multimeter probe tips while checking thermal expansion nodes via isopropyl evaporation or thermal imaging camera.
2. IC Communication Bus Evaluation (I2C / SPI) OSCILLOSCOPE

Determines why functional subsystems fail logic gates or system handshakes during boot stages.

Protocol: Attach digital storage oscilloscope ground strap to chassis ground shell. Probe Clock (SCL) and Data (SDA) lines. Check pull-up resistor structures against reference values to ensure data signals clear the threshold limits cleanly.

Computer Hardware & System Troubleshooting

// VRM Power Stage Evaluation

Testing multi-phase CPU Voltage Regulator Modules (VRMs) for driver degradation, high-side buck converter breakdown, and output choke ripple processing using electronic dummy loads.

// Non-Volatile Data Tracing

Recovering bricked computer firmwares by directly clamping external EEPROM SPI flash tools over bios structures, pulling hexadecimal binary images, clearing dirty ME-regions, and flashing fresh configurations.
