The machine lasted 6 hours. Just long enough for me to set it up for a customer. After getting everything transferred from the old computer and installing all of my clients programs, I decided to restart it. The machine wouldn't even post bios. I tried shutting it off, unplugging it...etc. Nothing worked. Before sending it back I had to remove my clients info so I removed hard drive and hooked to my dock and deleted all of how files. I noticed at this time the hard drive was 5 years old!? These machines are NOT refurbished, ni manufacturer would send a machine out with a drive that old inside! It's a ticking time bomb. I wasted 6 hours of my time for absolutely nothing!!
