Hot and Warm swapping support for ACPI-supported ThinkPad models One of the advantages that an ACPI-based portable computer offers while running Windows 2000 is full Plug-and-Play support for devices located in the UltraBay II or UltraslimBay slot of your ThinkPad computer. Such devices include the following: o IDE hard drive o LS-120 Super Disk drive o ZIP 100 drive o IDE CD-ROM and DVD -ROM drive o Secondary battery pack o Diskette drive Each device can be dynamically inserted and removed from the swappable bay slot without having to completely turn off the computer. The type of Plug-and-Play support and functionality for the swappable bay is very similar to PC Card, CardBus, and USB devices being inserted into their respectable slots. Depending on your type of ACPI-supported ThinkPad computer, Windows 2000 supports two types of swapping: Hot and Warm. Warm swapping: Under Windows 2000, you can perform warm swap after the computer is placed into Standby mode. Just before the system enters Standby mode, Windows 2000 will properly "stop" the device in the swappable bay slot. After the computer enters Standby, the user can safely remove the device from the computer . In order for warm swapping to function properly under Windows 2000, this operation must be initiated using the "Unplug or eject hardware" icon in the desktop Taskbar. Hot swapping: Under Windows 2000, you can perform a hot swap while the computer is "running". You can remove or insert an device from the swappable bay without turning off or placing the computer into Standby. The user can safely swap in and out different devices from the swappable bay slot by clicking the "Unplug or Eject Hardware" icon in the desktop Taskbar or pressing the eject request button. Note: The above swapping capability is only supported on ACPI ThinkPad models. On APM models, only cold swappingis supported. Although Windows 2000 and your ThinkPad computer BIOS support these features, some applications, such as anti-virus software, do not always support IDE storage-device swapping. If such an application has access to these devices, the application software will permit or prohibit removing a device when the user requests device ejection. Please consult with your application vendor for information your application and storage-device swapping.
