Circuit diagram package for Dell Inspiron N5110, also listed for M5110, stored in a 1.34 MB RAR file. The name gives no board number, revision or GPU variant, so check what the PDF inside covers. Dell boards of this era carry an ODM project code on the PCB, which should be compared with the schematic title block. The diagrams help with power-rail tracing, locating MOSFETs and test points and checking short circuits. Extract using 7-Zip or WinRAR.
