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
Suspend 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.
The default setting is [Disabled]. Changing the setting to [Enabled] enables
the use of this function.
There are four modes, Mode1, Mode2, Mode3 and Mode4 in [Enabled]. For
normal use, set-the setting to Mode4.
■ 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 tha
tinterfaces 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.
If the function does not work with Mode4 setting, change it to Mode1,
Mode2 or Mode3. Some external devices may not be able to use this
function in either mode. When this happens, change the setting to
[Disabled].
