Israel, Thank you! Finding the modules was the key to answering my questions. I found the same two modules (acer-wmi.ko and hid-lenovo.ko) and lsmod | egrep 'wmi | lenovo' gives: wmi 24576 2 wmi_bmof,ideapad_laptop In answer to your questions: I used unetbootin to create a live Lubuntu 16.04.3 on flash drive. I assumed that unetbootin checked the md5sum. I executed Lubuntu "Software Updater". I decided to try re-installing. I am now on release 4.13.0-26-generic, which is the same release that failed previously. This time I see no problems. My conclusion is that I previously had a corrupted kernel. The clock gives London time on Windows and Los Angeles time on Lubuntu. I'll check cmos battery.
