Lenovo B470 schematic for the board designed by Wistron, with the number LA47 10250-1 and a 1104 code that may be a date or revision. Wistron boards carry numbers in this pattern, usually printed on the PCB, which allows a quick match. The 1.84 MB PDF opens in any viewer and helps with tracing power rails, checking the charger and regulators, following the power sequence and locating parts on a short. Confirm the number and revision on your mainboard before relying on component values or test points.
