Operating Basics
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.

Enabling USB Sleep and Charge
This utility can be used to enable and disable the USB Sleep and Charge
function.
■
The USB Sleep and Charge function only works for compatible ports.
This function is disabled in the default setting.
■
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 USB Sleep and Charge function 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.
■
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.
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.
