Firmware set for the MSI GE620DX notebook, board MS-16G51 revision 2.0, including both the BIOS and the EC (embedded controller) firmware. The EC handles power sequencing, battery charging and the keyboard, so a corrupted EC image can stop the board turning on even when the BIOS is fine. MS-16xx is MSI's own board numbering. Flash each image to its own chip with a suitable programmer, confirm the revision on the PCB and back up both chips first.
