Ultrabay Fx Device Swapping With Thinkpad Models 390, 390E, & 390X - Lenovo ThinkPad 380E Setup Manual

UltraBay FX device swapping with ThinkPad models 390, 390E, & 390X:
The UltraBay FX slot holds the diskette and CD-ROM combination drive unit. You
can swap a diskette and CD-ROM (or diskette and DVD -ROM) combination drive)
combination drive with a secondary IDE hard disk drive, or a secondary battery pack.
Because of the hardware design for all ThinkPad 390 Series computers, only warm-
swapping can be performed under Windows 2000. In order to swap out a device
from the UltraBay FX slot, you must stop the device by clicking the "Unplug or Eject
Hardware" icon located on the desktop TaskBar. By doing this, the operating system
can properly stop the device and unload the necessary drivers before placing the
machine into Standby mode. After the system enters Standby, the user can then
physically remove the device and insert another, if desired. This also applies when
warm swapping and IDE hard disk drive.
A secondary battery pack located in the UltraBay FX slot can be warm swapped at
any time. For a secondary battery, Windows 2000 does not offer a similar
mechanism to eject the battery through the operating system as there is for a CD-
ROM and diskette combination drive device. In order to "swap" a secondary battery,
simply place the computer into Standby, then remove or insert the secondary battery
from the UltraBay FX slot.
With the ThinkPad 390 Series models, Windows 2000 assumes a diskette drive is
present regardless of whether one is physical attached or not. The drive letter A is
fixed and assigned to this diskette drive device. If the floppy diskette device is not
physically attached on the computer while Windows 2000 is running, the drive letter
A will still appear in Explorer. This is a design limitation on this system.
