User 's Manual
Procedure
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. 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.
n Change the Power supply mode settings in the
TOSHIBA USB Sleep and Charge Utility.
n Turn OFF the computer while external devices
are connected.
n Connect external devices after turning OFF of
the computer.
If this function can not be still used, change the
setting to [Disabled] in the BIOS Setup and stop
using this function.
When "USB Sleep and Charge function" is set
to [Enable], USB bus power (DC5V) will be
supplied to the external device connected to the
compatible port. If external device is connected
to the compatible port when the AC adaptor is
not connected to the computer, the battery of the
computer will be depleted even when the power
of the computer is turned OFF.
Connect the AC adaptor to the computer or
change the "USB Sleep and Charge function"
setting the [Disable] or if there is a USB port
that does not have the USB Sleep and Charge
function-compatible icon ( ), use that port.
