Great information from this post, my question is we input 19v but in the circuit we have 5v and 3v,, what the 19v for?

[@electronicsrepairbasics_erb]

The 19V input is the main power source for the laptop. This voltage is typically regulated down by different power management circuits to supply the necessary lower voltages like 5V and 3.3V. These lower voltages power components such as the logic circuits, USB ports, and other peripherals. The 19V is primarily used to power larger components like the charging circuit and can also be stepped down for specific system needs. Let me know if you need further clarification
