USB Sleep and Charge Utility
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.
Enabling USB Sleep and Charge
This utility can be used to enable or disable the “USB Sleep and 
Charge function” group.
Check the check box for the group to enable the “USB Sleep and 
Charge function” for the USB port assigned to that group. In the 
default state, the group is disabled.
Power supply mode settings
There are several "USB Sleep and Charge function" modes.
The default setting is Mode-1. Select one of the other modes in the 
drop-down menu of the USB Sleep and Charge window if the 
charge function cannot be used in Mode 1.
In this situation, select a different mode. “USB Sleep and Charge 
function” may not be functional with some connected external 
devices even if the appropriate group is selected. In this situation, 
uncheck the check box for the group and discontinue using this 
function.
