Compressed RAR package of 565 KB for the MV2 build dated 2008.06.11, tied to board number 6050A2161001 at revision A02. The 6050A prefix follows the numbering pattern used by Inventec, the ODM that produced many notebook mainboards for major brands, so the laptop brand itself is not stated here. Content is probably a schematic set used for tracing rails, checking power sequencing and finding test points. Make sure the number and A02 revision silkscreened on the PCB agree before trusting component values.
