The 4 computers I bought have the same problem: shuts down without warning very often, once or twice a week, sometimes twice a day, it putting itself in a state of sleep in full use although I set up NEVER in "PC goes to sleep after", we do not know the cause. The battery in one of the purchased laptops ran out and it had to be replaced. It seems that the product is not well supervised before it is sold. I would not buy it again or advise anyone to do so.
