Schematic for the Acer G3-571, a Predator Helios 300 series laptop, built on Compal motherboard LA-E921P and supplied as a 4.66 MB RAR archive. The circuit diagram, usually a PDF, covers power supply stages, charging, the CPU and GPU sections and the signal connections between them. It is the main reference when tracing a missing rail, identifying a shorted capacitor or understanding the startup sequence. Board numbers with the LA- prefix come from Compal; check that the revision on your PCB matches the schematic.
