RAR archive of 827 KB containing a schematic in PDF format for the Adamo 13, the thin notebook sold under the Dell Adamo name; no board number or revision is given in the file name. A laptop schematic shows power rails, regulator circuits, the charging path and interconnect pinouts, useful for tracing a no-power or no-display fault. Extract it and read it in any PDF viewer, searching by net name. Compare the board revision on the PCB with the schematic title page before trusting component values.
