    Hi,

    Enter the BIOS (pressing F2 on startup) and try to check in Bios if keyboard support, usb support legacy (something like this) is enabled. It should help.
    Otherwise, playing with Bios up/downgrade (especially, downgrade) instead of keyboard problem, can lead to the full system crash with blank screen.

    Can you please tell us which BIOS version you have installed on your Satellite A100?

    To be honest Iíve never heard about something like this.
    Not enough power on USB?
    Which OS (operating system) do you use?
    Do you use original Toshiba recovery image or your own OS installation?
    Is chipset driver installed?
