Got the defective laptop on the day I received, The left and right buttons below the touch pad are not working, battery life zero, always have to be plugged in, F1 fan malfunction and laptop gets heated up with in one hour, the touch does not work properly, seems like they just repaired it to work for 3 months, I  should give a zero star but no option has to give one.never ever buy any product with them , I do not know how Amazon is encouraging such people to sell their defective electronics on their site.Defective laptop delivered on day 1, I need a refund for my laptop which is not working , I called them multiple times and they say 90 days is completed , but i called them even before 90 days  and messaged them , they just repair defective laptops and send to people , you cannot expect a laptop to work only for 15 days or from day one it had issues , i called them as soon as i received my laptop also such irresponsible people, they simply cannot escape saying that 90 days is over  and nothing cannot be done
