ACPI-supported ThinkPad models:
An ACPI ThinkPad computer can fully exploit the advantages of Windows 2000 power
management and Plug-and-Play support. ACPI power management features include various
power saving-modes, such as CPU throttling with thermal zone control, dynamic Plug-and-
Play configuration of docking station and port replicator use, T hinkPad UltraBay IDE device
hot and warm swapping, and dynamic device detection, and configuration for Plug-and-Play
display and monitor devices. ACPI functionality and support under Windows 2000 is highly
integrated with the system BIOS version used on your ThinkPad model. In order to take full
advantage of Windows 2000 power management and Plug-and-Play support, you must first
updated the system BIOS on your ThinkPad before upgrading or installing Windows 2000.
Important Note:
The System BIOS on your ThinkPad system must be updated before Windows 2000 is installed
or upgraded on your system. This is required for ACPI to function with Windows 2000 on your
ThinkPad computer.
