I currently have my lenovo yoga 710 (~2 yo, last fresh OS install a long while ago) with W10 set to go to sleep after 5 minutes on battery and 10 minutes on charge, but it seems of a mind of its' own in this regard, sometimes coming back to a locked laptop, sometimes not, for no particular rhyme or reason. I have no aftermarket nor lenovo battery management software, only f.lux, which shouldn't be doing anything other than modulating screen brightness twice a day. I have no software running as far as I can tell that might otherwise be overriding any of these settings. I have in the past messed around with services and forgotten what I've done but I can't see here how that might affect things and I doubt I would have turned off or adjusted any power settings. Any halp please?
