NMGLugers, Well this is trivial compared to the e-mail issues. My G570 still has display errors, but now running Debian Stretch (9.6) I see a way forward. I had to re-install Stretch from my own media, but it went quickly at home. Updated and looked for CPU tools and found iucode-tool, intel-microcode and firmware-misc-nonfree. Too bad about the last item, but some of the CPU microcode is non-free. I seem to be a little better, and time will tell. I had one screen disturbance today, but also one "Battery is Full" notice without a screen mishap. (the screen goes all snowy white and pastel for those not at our meeting.) I will continue testing and see if the microcode can fix BIOS errors/omissions as advertised. Thanks for all the help, Ted P.
