IBM ThinkPad X30 and X32 documentation compressed into a 4.40 MB RAR file, whose size suggests a fuller schematic set or a service manual. These small ultraportables share closely related boards, so one package covering both is common. Use it to trace power rails, locate connectors and components, and work through no-power or charging faults. The FRU or board number on the planar itself should be compared with the documents before part values are trusted, since board revisions changed during production.
