This is one of the most annoying things about computers. If I want to shut it down, shut it down!
When the IBM 303X/308X/309X processors were the state of the art, the power switch was labeled Power Off Request . This initiated a microcode and control processor sequence to start saving critical system information to disk (unfortunately not the OS information itself).
The only way to really shut the system down right now (with no guarantees that it would come back up in anything approaching a reasonable time frame) was the Emergency Power Off switches on each cabinet.
Unfortunately for the customer, this method required a visit from the CE in order to recover (you can't use this method and then say "I don't know what happened" - it's obvious and billable).
