A stab in the dark:

I take it that you ran the upower --dump command while the battery was
discharging. 10,916 V looks a bit odd to me. What does a dump show when
the battery is fully charged? I wonder if that voltage is too low to
support the laptop.

My two ancient Lenovos (2011 and 2012) are both showing much better
values than that.

The difference between the energy-full and energy-full-design values,
and the capacity both lead me to wonder if it isn't time to buy a new
battery (or maybe a new or refurbished laptop).
