That's right: those things have a charge controller which should take
care of that (at both ends: overcharge, because *boom*, and that's
expensive for the manufacturer, ask Samsung [1]) and deep discharge.
Unless the charge controller is somehow defective -- and they are all
a bit, because it's a tradeoff: if you just allow 70% max charge
wrt what is usual, your battery pack will live quite a bit longer,
but you can't boast "8 hours" or something. I wouldn't expect that
from Lenovo, but what do I know?
