Problem

Procedure

USB device does not

work

Remove the USB device from the computer and

then reconnect it to a free port it in order to

ensure it is firmly attached.
Ensure that any required USB device drivers are

properly installed - to achieve this you should

refer to both the device documentation and the

operating system documentation.
If you are using an operating system that does

not support USB, you are still able to use a USB

mouse and/or USB keyboard by setting the USB

KB/Mouse Legacy Emulation option within the

TOSHIBA HW Setup utility to Enabled.
If you are still unable to resolve the problem,

contact your reseller, dealer or service provider.

Problem

Procedure

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 USB 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.
