USB Sleep and Charge function

For more information and settings, please refer to the Using the TOSHIBA USB Sleep and Charge Utility section in Chapter 4, Operating Basics.

ProblemProcedure

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].

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.
