Now I work for a point of sale company. I have handle to many Dells than I care to admit. So fortunately I know what to troubleshoot when I run into problems. We put our own image on the hard drives. So taking the lid off is an important part of the process. I had one 7010 that the lid would not come off. Upon closer look they had put the wrong lid on this 7010. To be fair a lot of Dell lids look the same. So when I go over a "new" refurbished Dell I am in and out of the case a couple of times.Which means that this Dell only was opened once. I am fortunate enough to have spare Dell covers that will work with the 7010. Not every customer will be as fortunate. I have ordered a lot of refurbed Dells in my career. This is a first with the wrong cover.
