I want to say upfront that my model is over a year old and worked well until a week ago.  I also did not buy it from Amazon. A Microsoft update caused my computer to go into a loop and I could not get out of it.  I called Lenovo support and after a while they told me that a Microsoft update had crashed my computer because a driver update hadn’t been installed.  I have my computer on automatic update!So Lenovo told me since my computer was no longer under warranty I would have to pay about $70 to fix my computer that they admitted had been wiped clean. So I have to pay for a mistake Lenovo and Microsoft caused.  This is so sad!
