This function can only be used for ports that support the USB
Sleep and Charge function (hereinafter called “compatible
ports”).
Compatible ports are USB ports that have the ( ) symbol
icon.
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, turn the power of the
computer ON to charge the device.
❖The “USB Sleep and Charge function” only works for compatible
ports.
❖When “USB Sleep and Charge function” is Enabled, USB bus
power (DC 5V) will be supplied to compatible ports 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 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 (DC 5V)
function that interfaces with the power ON/OFF of the computer
may always be in an operational state.
