The “USB Sleep and Charge function” only works for compatible
ports.
When “USB Sleep and Charge function” is Enabled, USB bus
power (DC 5V) will be supplied to compatible ports even when
the power of the computer is turned OFF.
USB bus power (DC 5V) 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 (DC 5V). 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 (DC 5V)
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 (DC 5V)
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.
USB Sleep and Charge function Settings—The default
setting is Disabled. Changing the setting to Enabled enables
the use of this function. To change the setting, launch
TOSHIBA Hardware Setup and click on the USB tab. There
are two modes, Mode-1 and Mode-2 in Enabled. For normal
use, set the setting to Mode-1.
