Archive for LX3 and LX5 boards on the Intel Huron River platform, with a DV6 tag suggesting use in the HP Pavilion dv6 line, though the brand is not given separately. Huron River is the Sandy Bridge generation mobile platform. A matching file of identical size exists, so the contents are probably the same schematic. Technicians use it to trace power sequencing, check regulators and find test points. Confirm the board number on the PCB before relying on any values.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @generalschematics. Enginerys does not host this file.
