BIOS firmware for the Lenovo ThinkPad L560 on motherboard LA-C421P, revision 1.0. The LA-xxxxP format is the numbering used by Compal, the ODM that produced this board for Lenovo. The 8.65 MB RAR may include more than one image, so check the contents and chip assignment. Use it to reflash the SPI chip with a programmer when the board shows no POST, after saving the original dump. Verify the board number and revision on the PCB, and ensure the file size fits the chip.
