Had a similar issue once and it turned out to be a powered USB hub backfeeding and putting the motherboard into an odd power state, only figured it out when I noticed a status LED remaining on after I physically unplugged the main power for the computer. May be worth unplugging any hubs you may have to rule that out
I mean, that seems pretty normal? I’m about 70% sure they must have shown some of those 250 or whatever gallon tanks that get filled monthly or so at some point, and having that as a recurring bill rather than ordering it every month seems entirely reasonable
