Archive for the Dell Inspiron 1150 (written Inpiron) with board reference LA-1684, the numbering style of the ODM Compal. At 929 KB it matches the size of the other LA-1684 package and is likely the same schematic content. It is useful for checking power rails, following the boot sequence and locating parts around shorts. Unpack it, then check the revision printed on your mainboard against the schematic, because Compal boards can differ slightly between revisions.
