Thanks Everyone for your continued assistance. I still have questions, I regret to say. I selected to have no password to login to Mint. It is asking for password every time it sleeps. I tried to set it never to sleep, and I can't find where to change that very annoying trait. Can someone give me guidance on how to correct this issue. I'll try to research possible commands to use in terminal. I had to rescue the machine from a hung boot loader by taking the CMOS battery out, which worked, yet returned after updating newly installed Mint 19.3. The continued need to enter the password has continued throughout.
