Archive for the LCFC board NM-A381, revision 1.0, under the Lenovo project code BTUU1. LCFC builds Lenovo laptops and prints NM-prefixed numbers beside the project code on the motherboard. The name does not reveal whether the 3.26 MB archive holds a schematic, a boardview or a BIOS dump, so extract it first. Match the board number and revision before using it to trace signals, measure rails against reference values or reprogram the flash chip, since component changes between revisions are common.
