I cannot use the USB 
Sleep and Charge 
function.

USB Sleep and Charge function may be 
disabled.

Select the “Enable USB Sleep and Charge” 
check box in the TOSHIBA Sleep and Charge 
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.
