We purchased a Lenovo ThinkCentre M900 from Amazon on June 24,2020. Up until a few days ago, it was working fine. But then it got extremely burning hot and hasn't turned on since.  I reached out to the seller to see if there was anything they could do.  They won't help us with replacement parts. All they told me was "I do apologize for the issue you faced but unfortunately, your computer is out of 90 days warranty and we can only provide you technical assistance but not able to replace anything."  Technical assistance was telling me to replace the cord and see if it would power on.  I would not recommend this purchase.
