ACPI-Enabled Laptop Prompts Twice for a Hardware Profile

ID: Q239697

The information in this article applies to:

Microsoft Windows 98
Microsoft Windows 98 Second Edition

SYMPTOMS

When you start a laptop computer that uses Advanced Configuration and Power Interface (ACPI) power management, you may be prompted for a hardware profile twice. If you create more than one hardware profile, and then restart your computer, you may receive a message similar to:

Windows cannot determine what configuration your computer is in.
Select one of the following:

Undocked
Undocked2
None of the above

You may then receive the following error message on a blue screen titled "Dock Change":

Windows is unable to determine your hardware profile. Is "Undocked" the current profile

Press Y for Yes or N for No

CAUSE

This problem occurs because the computer's BIOS supports both ACPI and Plug and Play. The real-mode boot sequence detects the Plug and Play BIOS and prompts for the profile, and then the protected-mode boot sequence detects ACPI support and displays a blue screen requesting the profile again.
