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
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.
■
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.
■
When “USB Sleep and Charge function” is set to [Enabled], the “USB
Wakeup function” does not work for compatible ports.
In that case, if there is a USB port that does not have the USB Sleep
and Charge function-compatible icon ( ), attach the mouse or
keyboard to it.
If all USB ports have the USB Sleep and Charge function-compatible
icon ( ), change the “USB Sleep and Charge function” setting to
[Disabled].
The “USB Wakeup function” will now work, but the “USB Sleep and
Charge function” will be disabled.
