I have purchased 3 refurbished Dell computers over the last 6 years.3 came out of the box and worked perfectly. in fact 2 are still in use.For the one that died I ordered another one. I fully expected to be as happy with the newly ordered one as all the prior ones.I hooked it up and registered to some company I have never heard of and it needs a sign on from the company or my office information.. It will not accept my office information. I returned it and ordered an upgraded one. paid more but thought it might be better.Same problem this one is registered to another company INVESCO. I called the listed help line and the person was nice enough but explained the the machine is registered to another company and to have it switched to me. I need to go out o google fill out and for and in 11 to 14 working days s dell will switch the registration to my name. This is crazy Amazon is selling refurbished machines, which by the way is great for the environment but this problem is unacceptable. Not one of the other machines had this problem. I will be returning this product.
