EC ROM dump for an HP Pavilion dv4 built on motherboard LA-4106P, a Compal-style board number, so Compal is the ODM. The 256 KB image holds embedded controller firmware, which governs power-on, battery charging, fan control and keyboard handling, rather than the main system BIOS. Flash it when a board shows power or charging faults traced to a corrupted EC chip. Confirm the LA number on the PCB, check the EC flash capacity matches 256 KB, and save the original contents first.
