Battery Working, but not Charging

OK, lets fix power usage first... (not worrying about indicator for now.)

sudo apt-get install powertop

sudo powertop

This ranks stuff running in order of power consumption.  but not
obvious, for example, first line on my laptop is bogus, assigning all
hardware consumption to an ethernet interface.  so since it is hard to
interpret, please just  copy/paste the first five lines to get an idea
of the top few processes running.

Generally:

Do you have two graphics cards (i.e. Nvidia Optimus?) ?
Having it use intel by default, and using primusrun to only use nvidia
when needed will save a lot of power as well.


How are your ACPI settings, if you a booting with ACPI=off... well
that's going to consume a lot.   Can you adjust screen brightness  ?
Need to know the specific brand and model of laptop to research solutions
as there are many variations in power management, ACPI settings and such.
