Hi, These 2 lines are not OK: > last full capacity: 25300 mWh ... > remaining capacity: 11900 mWh cause they should show the same value. Turn off the Thinkpad, disconnect the PSU, take the battery out. Press the power-on button several times. Reconnect the PSU and battery and check the values again. And try this if the first fails: http://www.thinkwiki.org/wiki/Maintenance#Reviving_batteries cu
