Pressing the UNDOCK button while the computer is in a power saving mode returns the computer to Normal mode first, and then initiates the disconnection process.
If you press the UNDOCK button while the computer is Hibernate, you may be prompted for password entry or fingerprint authentication when the computer returns to Normal mode. In such a case, enter the password or swipe your finger across the fingerprint sensor. See Using Fingerprint Authentication (page 83) for more information on fingerprint authentication.
