When you are using a docked computer, the computer may not be able to shut down, restart, log off, stand by, or hibernate. When you try to use any of these commands, the computer may appear to stop responding (hang).

Some types of docking stations may suspend the undocking process until the docking station is physically detached. If you leave the computer intact after you request undocking by clicking the
Eject PC or
Undock Computer command, or by pressing the undock switch, the computer may not be able to shut down, restart, log off, stand by, or hibernate because the pending undock process blocks all other operating system processes.

If you experience the symptom that is described in this article, physically detach the computer from the docking station after you request undocking by clicking the
Eject PC or
Undock Computer command, or by pressing the undock switch on the computer.

Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.

For Windows 2000, Microsoft recommends that Original Equipment Manufacturers (OEMs) implement their devices such that
the docking station suspends the undocking process until the docking station is physically detached if an IEEE 1394 controller exists in the computer and an IEEE 1394 device is installed in the docking station. This prevents Windows from potentially damaging data, which could occur if the device restarts if an OEM has designed a docking station system that cannot be isolated from the computer electrically.
