Hi,
normally, I run Linux (OpenSUSE Tumbleweed), and only two or three times
a year I boot to Windows 7. Last time I did so, there was a popup asking
me if I would limit charging the battery to 50% to extend it's lifetime.
I clicked [OK] assuming that it only affects Windows.
But when I booted to Linux again, I found that it charged the battery
only up to 65%. So it seems that the Windows function wrote it somewhere
to the firmware. Since I did not find an equivalent function withing the
Linux desktop, I tried to run it in battery mode until it switched off
to sleep mode. After that, the limit hasn't gone, but now it charges
only up to 25%.
Next, I booted into Windows 7 again in the intention to undo the
charging limit, but did not find something that is looking like that.
Maybe this depends on my lack of routine using Windows? Anyway, I'm
still hung at this state.
What can I do to get my Thinkpad charging to 100% again?

Its page is here:
https://linrunner.de/en/tlp/docs/tlp-linux-advanced-power-management.html
With this and a kernel with acpi call support you should in theory be able
to run tlp fullcharge and this will set the 100% charge threshold back.
I have a P50 I'll test with later today and report back. The old thinkpads
used to have tp_smapi for charge thresholds prior to Tx20 series.

After that, the battery is charged to 43%. This is better than 25%, but
less than the 100% I saw before.
Any ideas?

maybe there is an option in Windows. Since I know this OS only
incomplete, there might be someone who can tell me how to get it done
with Windows?

seems that I have a different Vantage tool since there are no drop down
menus. But I found the settings: 96% start, 100% stop, condition OK for
both batteries, but external battery state 0%? So I tried recalibration,
but over night it did nothing. It didn't charge the external battery,
it's still at 0%.
Maybe it destroyed my battery?
