Troubleshooting

I cannot use the "USB 

Sleep and Charge 

function".

The setting of "USB Sleep and Charge function" 

may be [Disabled]. Change the setting to 

[Enabled] in the TOSHIBA USB Sleep and 

Charge utility.

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. If this happens, disconnect the 

external device if one is 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.

■

Change the Power supply mode settings in 

the TOSHIBA USB Sleep and Charge Utility.

■

Turn OFF the computer while external 

devices are connected.

If this function can not be still used, uncheck the 

"USB Sleep and Charge" check box in the 

TOSHIBA USB Sleep and Charge Utility and stop 

using the function.

The battery depletes 

quickly even when I 

have 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 

uncheck the "USB Sleep and Charge" check box 

to disable this function in the TOSHIBA USB 

Sleep and Charge Utility.
