I am using dell laptop inspiron. its been one and half year old . From the day first the quality of the laptop is very poor, it hangs all the time , very slow , even in its first year it’s motherboard has been changed. And when ever I call service center they just say do this things , do updates do this do that .But no solution is given by them . I also mailed to dell company but no reply from their side . It 50000 black rectangular box with no usage.
