The first one purchased would fail to turn on until I unpluged it for about an hour.  Sent it back and ordered a second one.  In the first week I turned it on and it turned itself off about 5 minutes later.  After that point, it would not longer turn on.  Checked the internet and found multiple instances of this behavior.  Dealer was very good at providing refunds and my latest one is an I7 10th generation and so far I have had no problems with it.
