    I'm not sure a flat battery would give you a checksum error - its a bios error right?

    What is the MOBO and what date does the BIOS default to?

    The battery powers the CMOS (where the BIOS settings and info about the hardware is stored). If it fails, the CMOS will lose it's info, and the integrity check won't succeed (wrong checksum).
