Samsung NP-R428 schematic in PDF, covering mainboard BA41-01215A, with the token GCE also in the name, likely the board project name. The document is about 818 KB. Samsung numbers its own boards with a BA41 code printed on the PCB, so compare it before trusting values and part references. Use the drawing to follow power rails, check the charging and power-on sequence, trace signals and locate components around a short. Any PDF viewer opens it, and searching net names speeds up work.
