On day one a USB port wouldn't work it was broken real good inspection by the seller they said I could fix the problem by buying a hub they refunded me $12 for a hub. Less than a year later more USBs dead killed my wife's expensive headset for her job oh 90 day warranty yeah bought an extended Guess what time for claims. Never buying from this company again. Amazon quality refurbished bull. Who's quality?  Before the computer is sent back and taken out of service it says oh compatibility issues with your current monitor Make sure it's compatible yeah USBs are dying systematically Time for replacement. A note to the seller no this will not be retracted. I didn't take a picture of the USBs because I've dealt with this darn computer enough.
