I have a Dell Latitude E7490, and I want to turn on some kind of battery conservation mode. In particular, if the battery is, say, at 100% and I unplug it for a few mins, and the charge drops to 95%, I don't want it to charge back up to 100% when I plug it back in.
It appears that dell has a "longevity mode" for this, from a utility called "Dell QuickSet". However, this doesn't appear to be available for my model -- and on the Dell website, the screenshot is from XP, which isn't encouraging!
Such an application is very useful -- I had a Lenovo laptop prior to this, and it would only charge up to 60%, and not charge if above 50%, when "conservation mode" was on. I used this almost the whole time, as most of the time I Have my laptop on AC power. However, sometimes I go on quite long journeys, and it's helpful not to have to use the power cable, so I still want a long lasting battery
Any thoughts, anyone? :) – Sam T – 2019-03-06T10:13:13.030
