Hello BackMarket, As a loyal customer of your brand, I'm coming back to you regarding a problem with this order. I am surprised, even more than disappointed, to have received a PC without the speaker working, in other words a PC with no sound! In fact, I have reset the PC with an update from myself to Windows11. This operation SEEMS to have corrected the problem.... But how is it that the refurbished PC received has not been tested according to the specifications that you sell to customers .... I would like to thank you for your feedback, in the hope that this feedback will also serve as a commercial gesture and an explanation. With my thanks for the care you will take in reading my email. Best regards!
