Chapter 1. Getting to know your computer
„Connecting USB devices
You can connect a USB device to your computer by inserting its USB plug 
(Type A) into the USB port on your computer.
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 is installed, you can disconnect and reconnect the device without 
performing any additional steps.
Before disconnecting a USB storage device, make sure your computer has 
finished transferring data by that device. Make sure you properly eject the 
device from the Windows operating system, to avoid data corruption.
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.
Notes:
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.
When in sleep mode, you can only use keyboard instead of mouse to wake up the 
computer.
