Now, it shutted down around 10 %, didn't turn on blinking light, plugged AC in, booted to macOS showed 0 % unplugged the AC jumps to 20 %.
1. Fully charge the ProBook
2. Go to System Information and take a look at the Full Charge capacity. Note the value
3. Unplug the AC, refresh via Command + R, take a look again at Full Charge capacity and it changes. (First thing)
Not reproducible here. My full charge capacity is 4013 and remains the same after AC unplug.
4. Let it die until it turns off (note the battery % at which it turns off)
5. Now, you can't turn it on because of the dead battery.
6. Plug the AC in, turn on the ProBook, and now the battery shows 0 %
That would all be expected.
7. Unplug the AC and now the battery % should be more, like 15-20 % and also, the Full Charge capacity should be different in System information.
Did you install to APFS or HFS+J?
Note: Currently letting my 4540s run down the battery. Will try to note any stuck battery state. So far working fine (is currently at 99%, down from 100% a few minutes after unplugging).
