Ouch! But I don’t think you’re out of the woods yet!
Metal steel shavings just don’t appear out of nowhere! You need to find the source ASAP! Metal shavings can also cause a short across your logic board which could cost you big time!
I had to fix a few systems from tool maker (someone who creates metal tools) his desk is away from the machining equipment but the metal dust found its way mixing with dust inside made pathways from the power supply to the logic board! Damaging it.
Take the time to fully clean your system at least! And figure out the source of the steel metal filings.
