I installed the refurbished computer.  The process is quite easy.  But after the install was complete, my computer home screen had a message appear in a box that read "A cognizant audio device could not be found.  The application will now exit.  You can close out the message box only for it to appear again and again.  I purchased the Asurion warranty coverage so I called their tech support.  They tried to help me to fix it but to no avail. In the process of troubleshooting, we noticed that the computer was significantly behind in Windows updates.  Tech support thought that the problem might be due to that.  So I began the update process.  The update took some time so I left the computer.  When I returned, there was a message to restart the computer in order to continue.  I did that only to find the same message telling me to restart again.  That was it for me.  I had enough.  I shut the computer down and began the return process.  The good news is that Amazon sells refurbished computers with a 90-day return policy, without hassles.  This is the second refurbished computer I have purchased.  The first one lasted 2 1/2 years.  That is when I began to experience storage failures.  Thankfully, I purchased the Asurion warranty with it and was completely refunded.  After this experience with refurbished computers, even though the pricing is very attractive, I would think long and hard.  If you decide to give it a try I would highly recommend the Asurion warranty for peace of mind.  Not terribly expensive and it was quite handy with my first computer.  The company is very easy to deal with and they are happy to please.  Although I will buy a new computer for the third one, I will still purchase from Amazon along with their Asurion protection plan.
