Archive for the Lenovo ThinkPad X201i and R201i family tied to Wistron board number 08270-2, about 2.5 MB in RAR format. The name does not say whether it holds a schematic, boardview or BIOS, so open it to check the contents. Wistron numbers its laptop boards with a five-digit project code and a dash revision, so -2 marks a later spin than -1. Material like this helps a technician trace rails and signals or locate parts. Confirm the number printed on your board before using any data.
