Toshiba PORTEGE R700 - Manual (Page 165)

Problem Procedure
I cannot use the
"Sleep and Charge
function". USB Sleep and Charge function may be disabled.
Select the "Enable Sleep and Charge" check box
in the TOSHIBA USB Sleep utility to enable this
function.
When there is a current overflow of the external
device connected to the compatible port, USB bus
power (DC5V) supply may be stopped for safety
reasons. When this happens, disconnect an
external device if some external devices are
connected. After that, turn the power of the
computer ON/OFF to restore the function. If this
function can not be still used even if only one
external device is connected, stop using the
external device because its current is over the
acceptable value of this computer.
Some external devices may not be able to use the
"USB Sleep and Charge function". In this case,
please try one or more of the following methods.
Select another mode.
Turn OFF the computer while external devices
are connected.
Connect external devices after turning OFF of
the computer.
If this function can not be still used, change the
setting to disable the function and stop using this
function.
The battery depletes
quickly even when I
turned OFF the
power of the
computer. If USB Sleep and Charge function is enabled, the
computer's battery will discharge during
hibernation or when the computer is turned off.
Connect the AC adaptor to the computer or disable
the USB Sleep and Charge function.
