The first few pages of the document outline how the SoC (System on a Chip) interfaces with peripherals. Because the Celeron or Pentium CPU on this board combines the processor, graphics, and memory controller into one package, the diagram shows simplified traces going directly from the SoC to the storage, display, and input interfaces. 2.

The EC (often an ENE or ITE chip) governs the power-on sequence, keyboard matrix, battery charging, and fan speed. The schematic reveals the pinouts connecting the EC to the SPI Flash ROM chip where the BIOS firmware resides. Miscommunication between these two components is a frequent culprit behind a "dead" laptop. Common Repairs Solved by the LA-G121P Schematic No Power / Totally Dead Board
