Help please using a new Lenovo laptop with W10.
Because of the virus and ensuing lockdown, I have not been able to get a knowledgeable friend to show me around the device. And I find, over time, that I am forgetting more and more of the little I used to know. For example: what is the name of the operating mode in which the screen turns black-and-white; and DOS-like command lines are displayed? Seems to me the word Command Prompt was involved.
What is that mode called? How do I switch from normal mode W10 to it? How can I learn the designation (E: or D: or whatever) of a USB port into which I can insert a thumb drive? Where can I find an empty USB port?
I welcome your help. Thanks. ….. batpark
