Quanta BDBD motherboard schematic for a 17.3-inch laptop on the Intel Shark Bay platform, revision 2A, as a 1.46 MB PDF. Shark Bay is the Intel Haswell-era platform, so the power pages cover the CPU, memory and 8-series PCH supplies. The document suits tracing power rails and signals, locating test points and components and checking the startup sequence on a dead board. BDBD is a separate project from BDBE, so verify the code and revision on the PCB before use.
