PC Card in Dock Not Enumerated When Hot Docking (192067)

SYMPTOMS

If a portable computer is ejected from and inserted into its docking station in either a "warm-docking" or "hot-docking" operation, 16-bit PC Card devices in the docking station may not be enumerated correctly.

CAUSE

This problem has been reported to occur with the following portable computers and docking stations:

Hewlett-Packard OmniBook 7100 and OmniBook Full Docking Station
IBM ThinkPad 560D and ThinkPad Port Replicator w/Advanced EtherJet feature
IBM ThinkPad 380Z and ThinkPad Port Replicator w/Advanced EtherJet feature

The docking stations with which this problem occurs share the characteristic of having a separate internal PCI bus that is connected to the laptop computer's internal PCI bus through a PCI-to-PCI bridge.

RESOLUTION

It is possible to work around this problem by ejecting and reinserting the PC Card after docking the computer, following these steps:

Double-click the PC Card (PCMCIA) Status icon on the taskbar to display the PC Card (PCMCIA) properties.
In the list of sockets, locate the socket that is neither labeled as "(Empty)" nor as containing a PC Card device. Click that socket in the list, and then click Stop.
Remove the PC Card from the docking station. You should hear the PC Card removal sound, if such sounds are enabled on your computer.
Wait a few seconds, and then reinsert the PC Card. You should hear the PC Card insertion sound, if such sounds are enabled on your computer. The inserted PC Card should appear on the list in PC Card (PCMCIA) properties, and the device should be functional.
