My son used it at school for 91 days.  It failed on day 91 one day after warranty ended. Black screen when trying to turn it on, never started again.  Sent id to local shop and returned with a diagnostic of mainboard failure.  Repairing it costs more than a new one when you are abroad.Very disappointed with the product.  It is not the first time I buy renewed laptops, this one made me think that renewed devices ara a gamble.Never buying renewed devices again.  Go full price, go full warranty.
