SYMPTOMS

When you attempt to hot dock or undock an IBM ThinkPad 770 series laptop, you may receive an error message that says the hardware profile cannot be changed. In most cases, the computer's primary IDE controller is listed in the error message as the device that is preventing the computer from being docked or undocked.


CAUSE

This behavior can occur if you configure both docked and undocked profiles in Microsoft Windows 95, and then you upgrade to Windows 98 or Windows 98 Second Edition.


RESOLUTION

WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

For information about how to edit the registry, view the "Changing Keys and Values" Help topic in Registry Editor (Regedit.exe) or the "Add and Delete Information in the Registry" and "Edit Registry Data" Help topics in Regedt32.exe. Note that you should back up the registry before you edit it. If you are running Windows NT, you should also update your Emergency Repair Disk (ERD).
To resolve this issue, delete the 71118086 binary value in the following registry key:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VxD\PCI
