I believe that the charging hardware on Thinkpads is OS independent.

Lenovo provides a GUI for Windows to adjust the charge thresholds and
reset the battery level monitors (by running the battery to zero and
recharging).  This same functionality is provided in Linux/Ubuntu by
tlp.  However, I can see from your tlp-stat output that you have not
installed acpi_call.  This is not a problem, but acpi_call allows you to
adjust the Lenovo charging thresholds.

Since you have not manipulated the charging thresholds under Ubuntu
(since you have not installed the acpi_call module that would allow
this), if the dang thing is charging under Windows, it will charge under

So my guess is that you are misunderstanding or have misconfigured the
battery indictor (somehow . . .)
