Utilities
Sleep and Charge
When “USB Sleep and Charge function” is set to Enabled, USB 
bus power (DC 5V) will be supplied to the compatible port even 
when the power of the computer is turned OFF.
USB bus power (DC 5V) is similarly supplied to the external 
devices which are connected to the compatible ports. However, 
some external devices cannot be charged solely by supplying 
USB bus power (DC 5V).
As for the specifications of the external devices, please contact 
the device manufacturer or check the specifications of the 
external devices thoroughly before use.
If USB Sleep and Charge is enabled, the computer’s battery will 
discharge during hibernation or when the computer is turned off. 
It is recommended that you connect the AC adaptor to the 
computer when enabling the USB Sleep and Charge function.
Using the “USB Sleep and Charge function” to charge external 
devices will take longer than charging the devices with their own 
chargers.
If an external device is connected to the compatible port when 
the AC adaptor is not connected to the computer, the battery of 
the computer will be depleted even when the power of the 
computer is turned OFF. As such, we recommend that you 
connect the AC adaptor to the computer when using the “USB 
Sleep and Charge function.”
External devices connected to the USB bus power (DC 5V) 
function that interfaces with the power ON/OFF of the computer 
may always be in an operational state.
When there is a current overflow of the external device connected 
to the compatible port, USB bus power (DC 5V) supply may be 
stopped for safety reasons.
When “USB Sleep and Charge function” is set to Enabled, the 
“USB Wakeup function” does not work for compatible port.
In that case, if there is a USB port that does not have the USB 
Sleep and Charge function-compatible icon (
), attach the 
mouse or keyboard to it.
The “USB Wakeup function” will now work, but the “USB Sleep 
and Charge function” will be disabled.
Metal paper clips or hair pins/clips will generate heat if they come 
into contact with USB ports. Do not allow USB ports to come into 
contact with metal products, for example when carrying the computer 
in your bag.
