The Compal LA-C781P (ABL51) motherboard is commonly found in laptop models like the HP 15-af011ur. This board is designed for AMD-based systems, specifically utilizing the AMD Stoney Ridge or similar APU architectures. Core Components & Specifications

Critical Nets to Know:

• +PWR_SRC – Main power after protection MOSFETs (PQ101, PQ102).
• +3.3V_ALW – Always-on 3.3V for EC, RTC, and power button.
• +5V_ALW – Always-on 5V for USB ports (standby).
• RUNPWROK – Signal from EC to enable main VRs.
• SYS_PWROK – Final good signal before CPU reset.

Boardview Files: Many sources provide a .BDV or .TVW file alongside the schematic, which allows you to visually locate components on the physical board. La-c781p Schematic
