Enabling USB Sleep and Charge

This utility can be used to enable and disable the USB Sleep and Charge

function.
Check the "USB Sleep and Charge" check box. In the default state this

function is disabled.

■

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 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.

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.
