USB Sleep and Charge Utility
You can use the "USB Sleep and Charge function" to charge certain
USB compatible external devices such as mobile phones or portable
digital music players. 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, power on
the computer to charge the device.
❖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.
❖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.
