Wireless Switch (on selected models)
Enables or disables the built-in wireless LAN and
Bluetooth (selected models). When enabled, the wireless
status indicator will light. Windows software settings are
necessary before use.
ExpressCard Slot
One 26pin Express card slot is available to support one
ExpressCard/34mm expansion card. This new interface
is faster by using a serial bus supporting USB 2.0 and PCI
Express instead of the slower parallel bus used in the PC
card slot. (Not compatible with previous PCMCIA cards.)
E-SATA
E-SATA Port & USB Combo Port
External SATA or eSATA allows external connection of Serial-
ATA devices originally designed for use inside the computer.
It is up to six times faster than existing USB 2.0, & 1394 for
external storage solutions and is also hot pluggable using
shielded cables and connectors up to two meters. See USB
Port for description.
USB Port (2.0)
The USB (Universal Serial Bus) port is compatible with
USB 2.0 or USB 1.1 devices such as keyboards, pointing
devices, cameras, hard disk drives, printers, and scanners
connected in a series up to 12Mbits/sec (USB 1.1) and
480Mbits/sec (USB 2.0). USB allows many devices to
run simultaneously on a single computer, with some
peripherals acting as additional plug-in sites or hubs. USB
supports hot-swapping of devices so that most peripherals
can be connected or disconnected without restarting the
computer.
