USB Sleep and Charge function

Your computer can supply USB bus power (DC5V) to the USB port even

when the power of the computer is turned OFF. "Power OFF" includes

Sleep Mode, Hibernation Mode or shutdown state.
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.

This function is disabled in the default setting. To enable it, you must

change [Disabled] to [Enabled] in the HW setup.

When "USB Sleep and Charge function" is set to [Enabled] in HW

Setup, 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.
