    This probably won't help much, but I've seen similar on desktop
    motherboards, when an onboard (surface mount) silicon fuse had blown.
    This fuse was there to protect from short circuits in the PS/2 keyboard
    and mouse cables, but also delivered the 5V power to all the USB ports.
    Luckily I managed to locate it (near the keyboard PS/2 socket) and
    simply soldered a bit of wire across it. If it's that, you'll need to know
    what such a fuse looks like and test it with a multimeter (should be
    close to zero ohms) and be 100% sure, before risking this kind of fix.

    Shouldn't matter - OP says no keyboard in POST, so problem
    is OS-independant.
