Unit Arrive in a large bow with bubble wrap- Bubble wrap not taped and computer was flopping in the box - Checked for Physical damage and none found - Installed  unit and immediately came up with a No bootable device detected. Rebooted unit and windows loaded - Went into the bios and reset boot parameters. same error - Boot error every other Power Up. Performed a bios update and currently seem to be OK. I question the Definition of refurbished in this add - More like Loaded OS and Shipped - Definitely not tested properly. Inside needed cleaning, had to update bios. I any more problems arise, will be returning for a better unit that is actually done properly.
