Schematic in PDF form, packed in RAR, for a mainboard identified only as NDBW1401. The name gives no brand, ODM or revision, so verify that the code matches the silkscreen on your PCB before using it. A board schematic like this lets a technician follow power rails, check the power-on sequence and find the parts around a fault. It also gives pull-up and signal details needed when diagnosing a no-power or no-display board. The archive is about 2.5 MB.
