I purchased 4 of these laptops because I had heard refurbished was a good option for a computer.  Unfortunately I regret it.  ALL AC chargers (not OEM parts) I had to replace within 1 month.  One of the laptops battery went out.  When I tried to replace it, noticed someone had replaced it earlier which may indicate that there were changes done to the laptop that may have affected the quality.  I will no longer buy refurbished laptops unless I can confirm the quality ahead of time.
