Troubleshooting the Docking Station
197
An error message appears while disconnecting the docking
station, even after following the correct procedure for
disconnecting the docking station.
Close the software in use, disconnect other devices being used, then try to
disconnect the docking station from the computer.
I cannot remove the disc.
You cannot remove the disc when the computer is in power saving mode. Return
to normal mode, then press the Eject button.
The disc tray does not eject even after I press the Eject button.
Open the tray by inserting a thin, straight object (such as a paper clip) in the
manual eject hole.
