Use the schematic to identify the PWM IC responsible for generating the 3.3V3.3 cap V
If the 3.3V always-on rail is missing but 19V is present at the input pin of the IC, the regulator chip itself is likely defective or protecting against an external short. ✅ High-resolution scans – all layers legible (no

Usually labeled as +DC_IN or +PWR_SRC , this rail carries the raw 19V from your power adapter. Look at the schematic page containing the input MOSFETs and the charging IC. If this rail reads 0V, check the entry diodes, reverse-polarity protection MOSFETs, and current-sensing resistors. 2. The 3.3V and 5V Always-On Rails
