EC RGN

BIOS .bin 128 KB Shared

Embedded controller region dump, 128 KB, associated with Compal board LA-K321P. The name says only EC_RGN, with no brand, model or version. The EC firmware handles power-on, charging, keyboard and fan control. A corrupted EC region can cause no-power or no-charge symptoms even when the main BIOS is fine. Depending on the design, this region is stored in the shared SPI flash or in the EC chip itself. Confirm the PCB number matches, and back up the existing contents before writing it with a programmer.
