DDR3L or DDR4 SODIMM slots (Check page 11-13 of the schematic for exact voltage configurations).
Follow the power sequence to identify where a "dead" board is losing its voltage. Identify Components:
If you are dealing with a faulty ASL50 LA-C921P board, follow this structured diagnostic workflow to isolate the defective component. Step 1: Visual Inspection
If a specific area, such as the short around PL15 , is identified, use the schematic to see which chips (e.g., a SY8032ABC buck converter) are connected to that coil and test those components.
