Arrived with totally dead battery (One month after being “refurbished”)?  Plugged In, powered up, but failed to boot (indicating no boot device, failed drive?). Ran self diagnostic, passed, but still didn’t boot. Powered down and charged for 24 hours, same problem. Requested tech support callback, 12 hours later no call. RETURNING FOR REFUND.  I have frequently purchased refurbished equipment.  Being an electronics tech, I have performed many Warrenty return repairs, and feel that having a “real technician” test a product far surpasses assembly line “testing” but I guess the key word is “real technician” not some idiot that plugs a computer in, runs self diagnostic, and labels it good to go, even if it won’t boot up.
