Service archive for the Lenovo ThinkPad X200t convertible tablet, 1.73 MB in RAR format. The name gives no board number, ODM or revision, so inspect the contents to find out whether a schematic, boardview or other data is included. Such files help when tracing power rails, checking the charger and backlight sections, or locating components around a fault. Before using any values or layouts, compare the board identification inside the documents with the markings on the X200t motherboard, as tablet and standard X200 boards differ.
