Across large inductors near CPU (PL9 / PL10). Must be between 0.9V and 1.2V. If missing, inspect the ISL6265 voltage regulator and its power good (PGOOD) signal.

Jump to the Always-On PWM controller page. Check if the controller chip receives its VIN pin voltage (19V) and its enable signals ( EN or ENTRIP pins). If the chip gets hot, look for a low-resistance short circuit down the line on the +3VALW coil or the +5VALW coil.

2. Power Drops Immediately After Turning On (Three-Second Loop) Across large inductors near CPU (PL9 / PL10)

Successful troubleshooting of a dead 10203-1 motherboard requires a strict chronological understanding of the power-up sequence. Laptops do not turn on all voltages at once; they deploy them in distinct stages. Jump to the Always-On PWM controller page

Confirm that the power button signal successfully drops to 0V when pressed and rises back up, signaling the Super I/O to release the PM_SLP_S3# and PM_SLP_S5# states.

Check the AC adapter, RAM compatibility, ribbon cable connections, and CPU seating.

It's essential to understand the difference between a and a Boardview file. They are two parts of a whole.
