Mine was refurbed by AST Systems. I had some intermittent power management errors which ended up being caused by a bad battery. Email customer support was responsive and helped troubleshoot and then sent replacement battery. I was in no rush as it worked fine with the battery removed. Once replaced I've had no further problems. For $235 I could not be happier - at this price I was not expecting top notch performance and serious gameplay. It runs MS Office 2016 with no issues and easily supports net surfing which is what I'm looking for.
