What should I do if I cannot connect a USB device?
❑ If applicable, check the USB device is turned on and using its own power supply. For example, if you are using a digital
camera, check if the battery is charged. If you are using a printer, check if the power cable is connected properly to an
AC outlet.
❑ Try using another USB port. The driver software could be installed to the specific port you used the first time you
connected the device.
❑ See the manual that came with your USB device for more information. You may need to install software before you connect
the device.
❑ Try connecting a simple, low-powered device such as a mouse to test if the port is working at all.
❑ USB hubs may prevent a device from working because of a power distribution failure. We recommend you connect the
device directly to your computer without a hub.
Why can't I charge the USB device connected to the USB port that can supply power?
If your computer is off, in Hibernate mode, and in Sleep mode, connect the computer to an AC power source.
