Schematic in PDF format, 2.70 MB, whose name appears to begin with MBX149 followed by a random-looking string, which suggests a Sony MBX-149 notebook board, though no brand or revision is stated explicitly. Because the name carries little else, open the document and confirm the board number on its title pages before use. Such schematics are used to follow power rails, check the embedded controller and charging circuit, locate parts around a short and compare measured voltages with design values.
