Problem
Procedure
I cannot use the
Power Off and
Charge function.
Power Off and Charge function might be disabled.
Enable the
Power Off and Charge
function under
USB Charge
within the dynabook Settings.
When there is a current overflow of the external
device connected to the compatible port, USB
power (DC5V) supply might 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 still not be 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 might not be able to use
the Power Off and Charge function. In this case,
please try one or more of the following methods:
Turn OFF the computer while external devices
are connected.
Connect external devices after turning OFF of
the computer.
If this function can still not be 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 Power Off and Charge function is enabled, the
computer's battery discharges during hibernation
or when the computer is turned off.
Connect the AC adaptor to the computer or disable
the Power Off and Charge function.
External devices
connected to the
compatible ports do
not work when
connected to a
compatible port.
Some external devices might not work when
connected to a compatible port if the Power Off
and Charge function is enabled.
Reconnect the external device after turning the
computer ON.
If the external device still does not work, connect
the device to a USB port that does not have the
Power Off and Charge function or change to
disable the Power Off and Charge function.
