An optional external MultiBay or MultiBay II connects to the
notebook USB port or into an optional docking device (select
models only), and enables you to use MultiBay and MultiBay II
devices. The notebook does not provide power to the external

USB Devices
Universal Serial Bus (USB) is a hardware interface that can
be used to connect an optional external device, such as a USB
keyboard, mouse, drive, printer, scanner, or hub, to the notebook.
Your notebook model has 3 standard USB ports that support
USB 2.0 and USB 1.1 devices. An optional docking device
(select models only) supports additional USB ports that can be
used with the notebook.
✎Your notebook may look slightly different from the illustration
in this section.
USB hubs can be connected to a USB port on the notebook or on
an optional docking device (select models only), or to other USB
devices. Hubs support varying numbers of USB devices and are
used to increase the number of USB devices in the system.
Powered hubs must be connected to external power. Unpowered
hubs must be connected either to a USB port on the notebook or
to a USB port on a powered hub.

Using a USB Device
A USB device functions in the same way as a comparable
non-USB device, with one exception. By default, USB devices
do not function unless an operating system that supports USB
is installed in the notebook.
Some USB devices may require additional support software,
which is usually included with the device. For more information
and software installation instructions, refer to the documentation
included with the device.
Enabling or Disabling USB Legacy Support
USB legacy support (enabled by default) allows you to
■Use a USB keyboard, mouse, or hub connected to a USB port
on the notebook during startup or in a non-Microsoft®
Windows® application or utility.
■Boot from an optional external MultiBay.
To enable or disable USB legacy support:
1. Open Computer Setup by turning on or restarting the
computer, and then pressing f10 while the “F10 = ROM
Based Setup” message is displayed in the lower-left corner of
the screen.
2. Use the arrow keys to select Advanced > Device options.
3. Use the arrow keys to enable or disable USB legacy support.
4. To save your preferences and exit Computer Setup, use the
arrow keys to select File > Save changes and exit. Then
follow the instructions on the screen.
Your preferences are in effect when the computer restarts.
