Chapter 1. Getting to know your computer  
Connecting USB devices  
Your computer comes with two 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 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.  
Using memory cards (not supplied)  
Your computer supports the following types of memory card:  
• Secure Digital (SD) card  
• MultiMediaCard (MMC)  
Notes:  
Insert only one card in the slot at a time.  
This card reader does not support SDIO devices (e.g., SDIO Bluetooth, etc.).
