and output, and they include security features to protect against tampering. Industry-standard smart
cards are used with the smart card reader (select models only).
A PIN is needed to gain access to the contents of the microchip. For more information about smart
card security features, access HP Support Assistant. To access HP Support Assistant from the Start
screen, select the HP Support Assistant app.
Inserting a smart card
1.Hold the card label-side up, and gently slide the card into the smart card reader until the card is
seated.
2.Follow the on-screen instructions for logging on to the computer using the smart card PIN.

							Using a USB device
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.
Some USB devices may require additional support software, which is usually included with the
device. For more information about device-specific software, see the manufacturer's instructions.
These instructions may be provided with the software, on disc, or on the manufacturer’s website.
The computer has at least 1 USB port that supports USB 1.0, 1.1, 2.0, or 3.0 devices. Your computer
may also have a USB charging port that provides power to an external device. An optional docking
device or USB hub provides additional USB ports that can be used with the computer.
Connecting a USB device
CAUTION:To reduce the risk of damage to a USB connector, use minimal force to connect the
device.
▲Connect the USB cable for the device to the USB port.
NOTE:The following illustration may look slightly different than your computer.
You will hear a sound when the device has been detected.
NOTE:The first time you connect a USB device, a message in the notification area lets you know
that the device is recognized by the computer.
Removing a USB device
CAUTION:To reduce the risk of damage to a USB connector, do not pull on the cable to remove
the USB device.

To connect an external device to the computer:
CAUTION:To reduce the risk of damage to the equipment when connecting a powered device, be
sure that the device is turned off and the AC power cord is unplugged.
1.Connect the device to the computer.
2.If you are connecting a powered device, plug the device power cord into a grounded AC outlet.
3.Turn on the device.
To disconnect an unpowered external device, turn off the device, and then disconnect it from the
computer. To disconnect a powered external device, turn off the device, disconnect it from the
computer, and then unplug the AC power cord.
Using optional external drives
Removable external drives expand your options for storing and accessing information. A USB drive
can be added by connecting the drive to a USB port to the computer.
NOTE:HP external USB optical drives should be connected to the powered USB port to the
computer.
USB drives include the following types:
●1.44-megabyte diskette drive
●Hard drive module
●External optical drive (CD, DVD, and Blu-ray)
●MultiBay device
Using the docking connector
The docking connector connects the computer to an optional docking device, so that additional ports
and connectors can be used with the computer.
To connect the computer to a docking device:
1.Pull out the connect button (1) on the docking device to retract the locking mechanism.

							8Drives
Handling drives
CAUTION:Drives are fragile computer components that must be handled with care. Refer to the
following cautions before handling drives. Additional cautions are included with the procedures to
which they apply.
Observe these precautions:
●Before you move a computer that is connected to an external hard drive, initiate Sleep and allow
the screen to clear, or properly disconnect the external hard drive.
●Before handling a drive, discharge static electricity by touching a grounded surface.
●Do not touch the connector pins on a removable drive or on the computer.
●Handle a drive carefully; do not drop a drive or place items on it.
●Before removing or inserting a drive, shut down the computer. If you are unsure whether the
computer is off, in the Sleep state, turn the computer on, and then shut it down through the
operating system.
●Do not use excessive force when inserting a drive into a drive bay.
●Do not type on the keyboard or move the computer while an optical drive is writing to a disc. The
write process is sensitive to vibration.
●Avoid exposing a drive to temperature or humidity extremes.
●Avoid exposing a drive to liquids. Do not spray the drive with cleaning products.
●Remove media from a drive before removing the drive from the drive bay, or traveling with,
shipping, or storing a drive.
●If a drive must be mailed, place the drive in a bubble-pack mailer or other suitable protective
packaging and label the package “FRAGILE.”
●Avoid exposing a drive to magnetic fields. Security devices with magnetic fields include airport
walk-through devices and security wands. Airport conveyer belts and similar security devices
that check carry-on baggage use X-rays instead of magnetism and do not damage drives. 
Using hard drives
CAUTION:To prevent information loss or an unresponsive system:
Save your work and shut down the computer before adding or replacing a memory module or hard
drive.
If you are not sure whether the computer is off, turn the computer on by pressing the power button.
Then shut down the computer through the operating system.
