I purchased a open box dell laptop running window 10. It has random flickering cursor issue and does not upgrade to windows 11. There were some errors in log while trying to upgrade. When I purchased, I was told that it was fully tested and perform not difference than the brand new. The only thing that the techs can do is recommend exchange the laptop. They cannot do any debugging, try to fix even if I told them to take 1-2 weeks. Now the exchange guy is going to recommend you any other laptop without knowing what are the features you must have. That guy's recommended laptop was lower end in most of the resources. For that, he is going to charge you the difference in price. That is all your option if you don't agree, leave the laptop, take your money back and go. The open box is slightly economical but that does not mean you take it and if there are issues just return it. I see the serious quality/reliability issue with best buy. They are wasting your time/money. I don't know what their "thoroughly tested" standard means, the errors are right there in the eventlog which doesn't require a tech savvy to figure out. They took this as an opportunity to up sale their another laptop of their choice.
