Hello hello Norma, I have a Dell, one-year-old now, and knowing a little bit about these issues, and reading your case, sounds strange it is a problem due to Dell´s hardware communication with Windows at all. I have been using Dell last 12 years.
This issue you have now with Windows 10 as it was with the 11th version makes me assume that there is a major problem with Windows, not the hardware of the computer. Anyways, I am just a consumer.
A change of machine is a good thing; however, this solution sounds as a commercial solution by the book coming from your agent in Dell, more than an accurate technical solution.
I am in Costa Rica, so, I must wait until these guys solve the problem.
Have a nice weekend Norma, and the same to all readers.
PD: Keep me posted Norma, please, how does it go with a new computer.
