Disclaimer: Repairing electronics can be dangerous. Always disconnect power and batteries before working on a motherboard.
If the motherboard pulls excessive current or shuts down instantly, flip your multimeter to diode or resistance mode. Measure the resistance to ground on all major large inductors (coils) labeled on the schematic (+VCC_CORE, +VGA_VCORE, +1.5V). A reading below 1-2 Ohms on a CPU rail might be normal.
is vital. The board breaks down the initial input voltage into several low-voltage tiers using a series of pulse-width modulation (PWM) controllers and dual N-channel MOSFETs. 671w24h0d02a gp schematic
