I recently purchased a T460 with an Ultradock 90w and when the notebook is docked it only shows battery 1 (internal) as charging. Battery 2 is not being used but it is not charging either and it is very very slowly discharging (about 3% over the last few days). If I plug the Thinkpad into its normal power supply outside of the dock both batteries charge (one at a time). Is this normal behavior or is there something wrong with my dock?
