Understanding the core architecture of the ASL50 LA-C921P is the first step before diving into voltage injection or component testing. LA-C921P (Often labeled as ASL50/ASL51) Revision: 1.0
The laptop consumes 0.00A on a DC bench power supply.
Note: CPU and GPU coils will naturally show very low resistance (1 to 20 ohms). Standby coils (+3V/+5V) should read in the kilo-ohms or mega-ohms range. A reading close to 0 ohms on a standby coil indicates a direct short.

To help narrow down your troubleshooting on this specific motherboard, let me know:
The entry point of the 19V rail uses two N-channel MOSFETs to protect the board from power surges. If the laptop is completely dead and drawing 0.00A on a bench power supply, check if the 19V is passing through these two transistors. If the gate voltage is missing, the charging IC (often a BQ-series chip) is likely protecting the board from a short circuit further down the line. Shorted Ceramic Capacitors (MLCCs)
