The device does not have the processor indicated in BackMarket's technical description and on the Furbify Invoice - Core i7-1355U (13th generation) indicated vs Core i7-1270P installed.
I returned the PC, clearly explaining the problem (incorrect processor for the item), and Furbify sent me back exactly the same PC with the same processor installed...
By digging into the HP support website, I understood that this laptop model could only accommodate 12th generation Core i7 processors. So I gave up, but the technical specifications provided by BackMarket and its supplier are erroneous.
Furthermore, the 2nd PC sent by Furbify is not in "Perfect condition" as there are marks and scratches everywhere.
