I'm at a point in my life with technology where it either works or I return it.  When this minicomp failed to Even turn on, I didn't think twice before shipping it back for my refund.What gave me pause was the card in the box claiming that each computer have been quality checked to ensure function, but that if it didn't turn on these trouble shooting steps should help resolve it.  Including buying a new power adapter, taking the unit apart to replace/reset a battery, and other common solutions...How about: nope.Either it works or it goes back.What really concerned me was realizing during the return process that the i5 CPU of this computer is a Gen 4 and over 5years old.  A concern but not a deal breaker if there is value.  But not at $420. I thought I was getting more modern parts.... Not that it matters, since the unit failed to Even Start.Read carefully and do your homework before considering this product otherwise you might get burned.
