A low-resistance current-sensing resistor measures total system power draw. If a short circuit exists downstream, the charging IC immediately shuts off these entry MOSFETs to prevent catastrophic PCB burn. 2. Power Generation Rails (Always-On vs. Switched)

Laptops do not turn on all at once; they turn on in a highly specific, millisecond-by-millisecond sequence. The LQV77 schematic includes a power sequence chart detailing which voltage rails must become active before others. Common rails include: The main voltage from the charger or battery.
