 ) supports the following feature:
USB Sleep and Charge
System ON CDP Charge
USB Sleep and Charge You can use the Sleep and Charge function to charge certain USB-
compatible external devices such as mobile phones or portable digital
music players. Your computer can supply USB bus power (DC5V) to the compatible port even when the computer is turned OFF. "Power OFF" includes Sleep Mode, Hibernation Mode, or shutdown state.
To set USB Sleep and Charge feature, click  System Settings -> Sleep

When Sleep and Charge function is enabled, USB bus power (DC5V)
is supplied to compatible ports even when the power of the computer is turned OFF. USB bus power (DC5V) is similarly supplied to theexternal devices which are connected to the compatible ports.However, some external devices cannot be charged solely by
supplying USB bus power (DC5V). As for the specifications of the external devices, contact the device manufacturer or check the
specifications of the external devices thoroughly before use.
Using the sleep and charge function to charge external devices takes longer than charging the devices with their own chargers.
If Sleep and Charge function is enabled, the computer’s battery
discharges during hibernation or when the computer is turned off. It is recommended that you connect the AC adaptor to the computer while
using Sleep and Charge function.
External devices connected to the USB bus power (DC5V) function
that interfaces with the power ON/OFF of the computer might always be in an operational state.
User's Manual 5-11  
						

							When there is a current overflow of the external devices connected to
the compatible ports, USB bus power (DC5V) supply might be stopped
for safety reasons.
When Sleep and Charge function is enabled, the USB Wakeup
function might not work for compatible ports. In that case, if there is a USB port that does not have the Sleep and Charge function, attach the mouse or keyboard to it. If all USB ports have the Sleep and
Charge function, change to disable Sleep and Charge function. The
USB Wakeup function now works, but the Sleep and Charge function is disabled.
Metal paper clips or hair pins/clips can generate heat if they come intocontact with USB ports. Do not allow USB ports to come into contact withmetal products, for example when carrying the computer in your bag.
Your PC has multiple charging modes so that many different USB devicescan be supported for Sleep and Charge function.
Auto Mode  (Default) is suitable for a wide range of digital audio players.
While using  Auto Mode, your computer can supply USB bus power at
maximum 2.0A to the compatible ports while the computer is turned off. When USB device cannot be charged by  Auto Mode, change to  Alternate 
Mode .
This function might not be able to be used with some connected external devices even if the appropriate mode is selected. In this situation, disable
and stop using this function.
Some external devices cannot use  Auto Mode. As for the specifications of
the external devices, contact the device’s manufacture or check the
specifications of the external device thoroughly before use.
