On a computer that’s running Windows Vista SP2, you may be prompted to reactivate Windows each time you dock or undock your computer or add or remove other forms of removable hardware.

After undocking or removing a second monitor on a Windows Vista based computer, custom toolbars set to “Autohide” will be transparent and blank.

Consider the following scenario:

• You run Windows Vista or Windows Server 2008 on a portable computer that is equipped with a docking station.
• The portable computer is docked, and a USB mouse is plugged into the docking station.
• You put the computer to sleep, and then you undock the computer.

In this scenario, the computer is not undocked correctly.

When you undock the computer while it is asleep, the computer should resume and then automatically re-enter sleep mode. The computer resumes as expected, but does not automatically re-enter sleep mode. Eventually, the LCD screen turns blank. Sometimes, you receive the following Stop error message:

Stop 0×0000007E (c0000005, parameter2, parameter3, parameter4)
SYSTEM_THREAD_EXCEPTION_NOT_HANDLED

Notes:

• The parameters in the Stop error message may vary.
• This problem does not occur when both a USB mouse and a USB keyboard are plugged into the docking station.

When attempting to use Windows Easy Transfer to transfer user files to or from a laptop computer in a docking station using a USB cable, neither computer will progress past the “Install the Easy Transfer Cable and connect your computers” screen.

When you connect a portable Windows Vista-based computer to a docking station, you may receive a Stop error message that resembles the following:

*** STOP: 0×000000fe (0×00000006, parameter2, 0×48676643, 0×00000000)
BUGCODE_USB_DRIVER

This problem occurs if at least one of the following conditions is true:

• The computer uses a built-in charge-coupled device (CCD) or a built-in card-reader.
• A digital camera is connected to the computer through a universal serial bus (USB) cable.
