RAR archive for the Lenovo ThinkPad SL400, 824 KB in size. The name gives no board number, revision or content list, so the archive is most likely a schematic or boardview set but must be opened to confirm. Technicians use such material to trace power rails, find the charger and PWM controller circuits and locate test points when diagnosing a no-power or short condition. Before relying on it, compare the board number silkscreened on the PCB with the documents inside, since one model can ship with different mainboards.
