Schematic PDF for Inventec board 6050A2491301-MB-A03, packed in a 1.32 MB rar. The name carries no laptop model, though this number appears elsewhere in the index alongside a Toshiba Satellite L850. Inventec numbers start with 6050A followed by the project code, with the MB and A03 suffix marking the mainboard revision. Use the diagrams to trace power rails, the charging circuit and signal paths. Check that the PCB shows the same number and A03 revision before relying on part references.
