Did you buy it from Dell directly? If not you should go back to the establishment where it was purchased and lodge your complaints there, and see if they will offer a resolution.
No, I didn’t buy it direct from Dell. But after a year, it’s a little late to be crying to the seller.
I expected better service from Dell, at any rate, as it IS their product. The last time the techs had it, they set it to “Administrator” and I’m not knowledgeable enough about computers to take that off. I called Dell, and painfully listened to the guy’s rapid mangled English, and was able to by-pass the Admin requirements, but it is still there, waiting for an Admin to open it.
Another reason to have sent the darn thing back and tell them to keep it in a dark, moist place.
