This unit doesn't appear to be refurbished, just used. Everything was carelessly thrown into a box, without any concern that the computer would obviously be rattling around as the box was in transit. The keyboard and mouse have a greasy layer of filth. There was no wifi or Bluetooth installed. I considered sending it back, but there is an MVNE SSD (upgrade as it's faster than SATA SSD), and I lucked out with 16gb ram instead of 8. Power supply was also 150 watt. This is the second "refurbished" 800 g4 system I bought. I returned the first as the wifi didn't work, and with lesser power supply and SATA SSD. It seems that the components that are sent are luck-of-the-draw. I've ordered a 9560 wifi/Bluetooth card as luckily the internal antennae were there.  For another $18 it should be working fine. "Refurbisher" was thegadgetdeals.
