  I bought Dell Inspiron 15 3511 online on September 5, 2021. Delivered on November 6, 2021. It worked fine but I noticed a gap between screen and bezel  And on January 6, 2022 it broke and I could not even open/close the laptop  So I contacted customer support and a technician came with wrong parts for the first time on jan23 So he reordered suitable parts and said he'll come the next time too  Another technician came and he opened everything replaced the damaged bezel and front cover  Now it was showing a slight inclination in both hinges so we asked what the problem was with him he reopened everything and saw that there was a problem with new bezel so he replaced the replaced part with a spare bezel and closed it to normal and then it was not working(not even charging indicator) he tried another 30 min and said it has some battery issues we asked what the problem again was because he was some what passive so he reopened everything and it was not working he said due to cable removing and friction may be it has some motherboard issues so he rechecked everything again and tried and there was no sign of powering or any electricity then he was tensed and responded vaguely and said he'll get the issue done by the next day morning  We asked if we can provide accommodation and food for the night (the time was 9pm)  He rushed out without even eating and we returned home  Next day I.e today (13 feb 2021) he called in the morning with free tone and told us that the issue may be because of battery drain so I can just power on right now and it works normally And I tried it the situation did not change And he said me telling that we could provide for accommodation and food was an insult he resigned and he told  some stories I sent his video and photos to Dell support they say they'll take 2 days to respond and now I am waiting for a replacement or refund  I don't know if they sent a unqualified engineer or the laptop was so problematic I don't have hope that it can get repaired because even the engineer said that while opening and closing(the case) motherboard some problems which are hidden may resurface I don't understand him it was 3rd month after buying and opening the laptop  Either dell sent unqualified engineers or dell is responsible for frequent problems in laptop I hope dell responds fast to my grievance.  I am expecting a replacement because I don't know whether new problems arise.
