Firmware set with both BIOS and EC for the Lenovo B50-30, project code ZIWB0 B1-E0, on Compal board LA-B102P, packed in a 2.53 MB zip. The LA-xxxxP pattern is Compal numbering, which Lenovo used widely for consumer laptops. Many such boards keep EC code alongside the BIOS, so the correct image is needed for power-on and charging to work. Match the LA code and revision on the PCB, read and back up the existing chip, and verify the image size against the flash before writing.
