Lenovo B560 firmware package for board 48.4JW06.011 with the LA56 project code, containing both main BIOS and EC images in a ZIP archive. The 48.4xxxx.xxx format is typical of Wistron boards. With the EC file included you can also fix power-on or charging issues caused by corrupt embedded controller code. Program the images with an SPI programmer, confirm the board number on the PCB, and back up the original chips before writing.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
