Check your BIOS for an option that blocks keyboard "until the OS is up".
This bit may have been flagged in the BIOS memory by the power glitch. If
you can't find it, you can simply try to restore your BIOS to
factory/fail-safe conditions, or disconnect it from mains, pull out the
CMOS battery for a minute or so, and then return it..
