External Devices
USB hubs can be connected to a USB connector on the notebook
or on an optional Port Replicator, 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 connector on the notebook or
to a 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 loaded.
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 USB Legacy Support
You must enable USB legacy support to:
Use a USB keyboard, mouse, or hub connected to a USB
connector on the notebook during startup or in a non-
Windows application or utility.
Boot from an optional external MultiBay.
To enable USB legacy support:
1. Turn on or restart the notebook.
2. Press
F10 while the F10 = ROM Based Setup message is
displayed in the lower left corner of the screen.
To change the language, press
F2.
For navigation instructions, press F1.
