@noClue: I have no intention to get into polemics. I do insist on getting the record right: I may have been somewhat impatient and need to consider that people here are volunteers and have other things to do too. But I have NOT asked for a reply every couple of hours, OK? So, please do not exaggerate, to put it mildly.
The computer is indeed a hybrid – tablet/laptop. It ran perfectly well on Win 8.1/64-bit for 3 years, then the cursor froze and battery volume went to zero and could not be budged from there. No amount on internet research revealed a solution. I was ready to ditch it, when I decided to do a clean install of antiX, a nice & light OS, and wipe Windows completely. The cursor and battery issues did not recur, so were Win-related. The machine is running fine, no issues except the one I opened this thread for.
I must say that under Win the machine would reignite spontaneously when switched off, i.e. shut down. Could not get that fixed. Under antiX this issue has persisted, which indicates it is a hardware problem. Having said that, it is not serious in that 1x/week I shut it down completely for a short while to give the HD a rest, then fire it up again and @ the end of each day put it in suspension or when I am not using it for more than 30 mins.
The annoying thing is the keyboard disablement during suspension, although it does not happen after each suspension, and it did not happen under Win. As for hibernation, how do you do that? The Logout menu options are Lock screen, Log out, Restart session, Suspend, Reboot, Shutdown.
