If your search leads to a connector like the , you have the following options:
Find the charging IC (often a BQ-series) and the input MOSFETs. Look for the voltage divider circuits that allow the laptop to recognize the adapter type. 2. 3.3V and 5V Always-On Power Rail lah103p schematic new
The Compal LA-H103P motherboard (often sharing design lineages with the LA-H102P) is highly dense. It relies on a multi-stage power conversion process to downstep the 20V DC-in adapter voltage into steady, low-voltage rails for the CPU, RAM, and auxiliary controllers.
