 Connecting USB devices

Your computer comes with three USB ports compatible with USB devices.

The first time you plug a USB device into a particular USB port on your
computer, Windows automatically installs a driver for that device. After the
driver has been installed, you can disconnect and reconnect the device
without performing any additional steps.

Note: Typically, Windows detects a new device after connecting it, and then installs the

driver automatically. However, some devices may require you to install the driver
before connecting. Check the documentation provided by the device’s manufacturer
before connecting the device.

Before disconnecting a USB storage device, make sure your computer has
finished transferring data by that device. Click the Safely Remove Hardware
and Eject Media icon in the notification area of Windows to remove the
device before disconnecting.

Note: If your USB device uses a power cord, connect the device to a power source before

connecting it. Otherwise, the device may not be recognized.
