USB Sleep and Charge
When enter BIOS Setup Menu, please choice Advanced item then you can change or modify the USB Sleep and Charge
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 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 USBcompatible 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.
■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.
