However, the "USB Sleep and Charge function" may not work with certain 
external devices even if they are compliant with the USB specification. In 
those cases, turn the power of the computer ON to charge the device.
The default setting is [Disabled]. Changing the setting to [Enabled] enables 
the use of this function. 
There are two modes, Mode-1 and Mode-2 in [Enabled]. For normal use, 
set the setting to Mode-1. 
When "USB Sleep and Charge function" is set to [Enabled], USB bus 
power (DC5V) will be supplied to compatible ports even when the 
power of the computer is turned OFF. USB bus power (DC5V) 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 (DC5V).
As for the specifications of the external devices, please contact the 
device manufacturer or check the specifications of the external devices 
thoroughly before use.
Using the USB sleep and charge function to charge external devices 
will take longer than charging the devices with their own chargers.
If external devices are connected to compatible ports 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 (DC5V) 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 devices connected to 
the compatible ports, USB bus power (DC5V) 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 ports. In that case, if 
there is an USB port that does not have the USB Sleep and Charge 
function-compatible icon ( ), attach the mouse or keyboard to it. If all 
USB ports have the USB Sleep and Charge function-compatible icon 
( ), change the "USB Sleep and Charge function" setting to 
[Disabled]. However, the "USB Sleep and Charge function" is 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.
If the function does not work with Mode-1 setting, change it to Mode-2. 
Some external devices may not be able to use this function in either mode. 
When this happens, change the setting to [Disabled].
