Disappointing first attempt at purchasing something from Back Market. The laptop worked for 4 days before revealing significant hardware memory issues that rendered it completely unusable. It is impossible to boot into a normal Windows environment, and Dell diagnostics shows critical memory errors are present. The diagnostic logs reveal that these issues have been going on since early this year, and have persisted, meaning this is not an isolated or new issue and one which the vendor has failed to resolve properly. Given the quantity of diagnostic errors and logs, it’s hard to think the laptop wasn’t sold in bad faith to avoid more extensive hardware replacement.
