    Lenovo L580 with 01LW293 Motherboard, No power

    I've got a Lenovo Thinkpad L580 with a 01LW293 motherboard that doesn't power on, or respond to a charger.

    It's got 2 bios chips, U4502 located near the ac input (25L8006E)
    and U0901 located near the dimm slot (25L12873F).

    Can anyone tell me which bios is doing what?
    I'm guessing U4502 is corrupt causing everything else to fail.
    I've found the main bios image at 16M, but nothing for the 1mb one.

    Thanks.
