Ouch, and such a young one too! There's a message here - when Ma Nature
visits with lightning, unless you're an electrical engineer with a
perfect station configuration, the only relatively secure way to do
things is to disconnect everything. Even a relatively short length of
cable (RS-232, network, whatever) can pick up enough induced voltage
from a nearby strike to do damage.

Sounds like wind howling or something. The autotuner sounds like marbles rattling around instead of relays clicking. The KPA100 tests are all whacked out: PAIO TST turns on the fans. FN1 turns them both on at full speed. FN2 turns them both off. FN3 turns them back on again. FN4 drops the fans back off again.
