The past few (work) days, I have noticed that at the end of the day, Windows was reporting that my laptop was plugged in, my battery was not fully charged, and that the system was not charging the battery. On one day, Windows reported that the battery was at 60%, and on another day, Windows reported that the battery was at 61%. My case appears to have been identical to laptop battery level never reaches 100%. I performed a recalibration, as described in the accepted answer. After doing so, I allowed the battery to charge. Windows is now reporting that the battery is at 100% and fully charged.
Does this mean that at full charge, my battery is now only 60% of its original capacity?
