I had purchase a few of these to help out a client on a tight budget that needed to be compliant in his industry. We've never had an issue with previous devices so, I left this one with the other spares and today we really needed it but it never POST and I see no Indication of it getting power.Unfortunately, I'm beyond my 90 days yet within 1 year. Any decent tech could tell it hasn't been power on since it arrived.
