Computer arrived securely packaged and in good condition. Set up was a breeze, and so far, everything seems to be working correctly. Unfortunately, as others have noted, the internal 3 cell battery pack was missing. I contacted the seller, so hopefully the problem will be rectified with a battery being sent to me. Amazon support was worthless, only offered a return of the entire laptop. I felt purchasing a refurbished item was a roll of the dice, and feel fortunate to have received a functional computer in great condition. I certainly don't want to return the whole thing when it would be very simple for the seller to simply send me what's needed. I'll update when the issue has been resolved.
