Dell Latitude E5470: windows pointer on the black screen

Hello to all,

       I have a problem. I'm not sure it's a hardware problem but I found it on 40 new and just opened Dell E5470 (the model with finger sensor). The problem is on Windows 7 PRO. The Dell support team is not helping me even if I have bought the "professional support". I also called Microsoft support team and they replied me to call the Dell Support because the software problem...The Dell support told me to call Microsoft support because the harware problem...

The problem is the black screen with windows pointer; please take note that it is no blank screen: BLACK SCREEN and the cursors is the windows graphic pointer, no character cursor. I made many tests: factory restore, restore from the Dell ISO image downloaded from dell website. I didn't found a solution because even if I recovery or even if I restore, the problem reappears. When it appears, I can only do the configuration recovery; instead the safe start and all other ways after F8 don't work. I can only do, I repeat, the configuration recovery or factory image recovery. When the PC starts, I see the windows logo and after a while I see the black screen with the windows pointer and nothing else (and the login screen doesn't appear).

I work in a big company and all PCs & notebooks that we bought are Windows 7 PRO pre-installed (We cannot install windows 10 and other O.S.). When I install the notebook (please take note that I usually install hundreds of notebooks in the same way...); I confirm the language and the region (italian and Italy); I made an user "User" and after the login I disable the automatic updates and the power saver. I put the machine-name in our domain with the unique machine-name, I set the local administrator rights for the domain user the will use the PC and stop. After 2-3 hours if I reboot the notebook I'll see the windows screen "configuring windows features, xx% complete, do not turn off the computer" and after the reboot the black screen appears. The problem appears only after the windows feature screen notice... The last system recovery point set shows "language pack removal" and it is the same in all notebooks...I tried to unistall Dell's software, setup the BIOS, and many other actions that is too long to explain. Believe me: we tried many and many solutions without any results (I also tried to install the notebook without the domain but the problem appears).

Thanks to everybody. I hope to have explained in the right way and in the right forum.
