Since this board relies on USB-C for power, the CC lines and the USB-C Controller chip are high-stress areas. If the laptop won't charge, check the protection diodes near the USB-C port.
The LA-E801P Rev 2.0 schematic is likely used in various industries, including: la-e801p rev 2.0 schematic
: Often fails at the first input MOSFET. If 19V enters but doesn't pass the first stage, check the gate voltage and surrounding resistors. Since this board relies on USB-C for power,
