Schematic for a Z94 R board, revision 1.1, supplied as a PDF of about 902 KB. No manufacturer or laptop model appears in the file name, so identification relies on matching the board marking. Typical uses include tracing power sequencing, finding where a missing voltage stops, locating fuses and MOSFETs on the input stage, and checking signal paths between chips. It opens in any PDF viewer. Because a revision 1.2 sheet also exists for this family, check that your PCB is actually marked 1.1 before following component values.
