Bought one of these and updated it with Windows patches, Office, and other apps. After about 2 days it just quit booting into Windows. I called Amazon support and they quickly punted me to Lenovo support which could not help me because it was at least a year out of their warranty. I then ordered a replacement thinking I got a bad one initially but the second one failed to boot within a day as well. I did my own research and it wanted me to upgrade the BIOS. However, the bios was locked and needed an Admin password which of course I don't have. Sent the second one back for a refund and we just upgraded our old computer which has been working perfectly and should have been our initial route. Now I've been having to fight Amazon for the refund. Even though they say they received it and a refund would be 3 - 5 business days but it's been almost 2 weeks. Just be on notice that the tech support is terrible and even though they say you can get a refund the process is not going to be easy.
