Set your multimeter to resistance mode and probe every large inductor (coil) across the motherboard relative to the ground.

Print the power sequence page and keep it next to your workbench. In the world of LA-9413P repairs, voltage always tells the truth—you just need to know where to look.

Controlled by a dual step-down PWM controller (commonly the TPS51225R or equivalent), these rails must be active as soon as the charger is plugged in. la-9413p rev 1.0 schematic

rails. If these are missing, the 3.3V/5V PWM IC (usually a TPS51...) is not working.

The high-voltage 19V rail travels across the entire board to supply various buck converters. The small multi-layer ceramic capacitors (MLCCs) filtering this line frequently short internally.

While direct public downloads for the exact "LA-9413P" file can be difficult to find due to its proprietary nature, technicians often use documentation for nearly identical boards or purchase the specific diagram from dedicated schematic repositories.

Generated by a dedicated multi-phase buck controller near the CPU socket. This rail only activates at the very end of the power sequence, right before the system initializes the display.
