According to tradition, Archangel Michael helps out with technical issues when they arise, in addition to the many other offices he holds and fulfills. So when you find yourself requiring technical assistance of any kind – especially those most frustrating – and cannot find it, ask Michael to help you out and he will be happy to oblige.
From personal experience, it is safe to say that Michael is indeed a technical fixer. Moreover, when you have something technical (e.g., a machine, computer, etc.) which is vital in your line of work or other important purposes, entrust it sincerely to Michael and he will protect it from all kinds of damage which would otherwise impair its use.
