Schematic PDF in a RAR archive for a board labelled 162924 Buzz KBL UMA-2, meaning a Kaby Lake design with integrated graphics only. No laptop brand or model is named, and the number resembles Wistron project codes but should be checked against the PCB silkscreen. A schematic like this helps trace power sequencing, locate test points and follow signals between chips. Open it with any PDF reader and confirm the UMA variant and revision before relying on component values or net names.
