Inserting battery pack
If the port replicator is attached to your notebook, do not attempt to insert or remove 
the battery pack. Lifting and turning the notebook with a port replicator attached could 
cause a temporary loss of power.
To charge the battery completely, continue charging for an additional hour. See
