Archive for the IBM ThinkPad T23, a 1.60 MB ZIP whose name gives no board number, revision or description of its contents. Expect schematic or service material, but unpack and review the files before relying on them. For this older platform, such documents are valuable for tracing power distribution, finding test points and diagnosing no-power, short or charging faults. Check any planar part number or revision shown in the files against the markings on your motherboard, because IBM made changes across production runs.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @schematicslaptop. Enginerys does not host this file.
