They should have a reset to factory condition procedure. I don't have this here. But you might get such in the Dell forums. Start here: https://www.dell.com/community/Laptops/ct-p/Laptops
Alrighty so my inspiron 11 3000 isn't the most lovable of laptops... I liked its 2-in-one feature the best. Key word: Liked. After having it for maybe six months, the touchscreen became unresponsive. Only now have I dedicated myself to fixing the problem. I've done all the updates (including drivers), and I've ran the troubleshooter many times.. One big problem is that my HIV-compliant touch screen is missing from the device manager list. How can I restart it if it isn't even there?? Now, I really don't know much about computers. But, I can carry out instructions well. Sooo, if anybody has an idea, please share!
Thanks,
