Lenovo laptop schematic for motherboard NM-A181, revision 1.1, supplied as a PDF of about 1 MB. The NM- prefix is the numbering used by LCFC, the Lenovo and Compal joint venture that designs many IdeaPad and ThinkPad boards, although the file name still credits Compal. Use it to trace power sequencing, locate test points and work out which rail is shorted on a dead board. Check that the NM-A181 marking and the revision on the PCB match before relying on component values or page references.
